In other words, the use practicw the first tool to reduce the risk that is associated with the Each dataline is tokenized based on a function. When payment in Canadian dollars was received from the customer, she would use the proceeds to pay down the Canadian dollar debt. On the next post, I will post the whole algorithm and go line by line. The way the interbank system handles these events is. That's the reason why most of the "trading" databases have all their data in the same memory space and have custom languages doing the analysis like Kdb. Find out the role of the Reserve Bank of India, or RBI, and the amount of authority given to the government.

Update: I updated the practce so it works with Oanda's new API. Get it here Time to talk about brokers, how to place a trade programmatically and most importantly how not to get scammed. This is the third part of the series: How to build your own algotrading platform. A broker is nothing more than a company that lets you trade buy or sell assets on a market through their platform. What is very important for algotrading is: In our case, we don't really care about spread as we won't be doing High Frequency Trading any time soon.

Even though brokers are regulated, there have been incidents in the past couple of years, were brokers folded due to certain conditions. Be very wary if What could happen is that you start making some money and you aren't be able to pull them out. But let's switch fxtrade oanda practice effect a happier note which is opening an account and placing our first programmatic trade. I am using Oanda as a broker I am not affiliated with them and they offer a pretty decent API, libraries on github and a free demo account.

Go and open a free fxTrade Practice account and then sign in. After you sign in to pfactice demo edfect, go to Manage API Access. There you can find your API key which we are going to use in our system to place trades. MAKE SURE YOU DON'T SHARE THIS KEY. The code for this is and all other posts is on github and you can install it and run it pretty easily. Update: Oanda released a new kickass execution engine called v20 and they have released a new improved API.

This post has been updated in order to use the new API but if for any reason you want to check the old code, it is right here. Connecting to Oanda needs a conf file - which you can generate using a script that Oanda provides here or you can just create it yourself. Why would you want that? First of all when it comes to credentials and my moneyI prefer to know everything that is going on.

And I edfect like having to install PyYAML just to read a conf file. Feel free to use either method. Don't worry about what EURUSD is or how many units we are buying or what a market order is. For now, we have placed our first trade from our laptop and we are dxtrade to pratice our own API to place trades. You can read Oanda's documentation here to see what else you can do fxtrade oanda practice effect their API and find the Python library here.

Tons of examples are available from Oanda's github page here. Coming up next, connecting to a real LIVE algotrading system, running from my RaspberryPI at home. You'll be able to see the almost fxtrade oanda practice effect program running and we'll talk more about Forex and strategies. If you have more feedback, ping me at jonromero or signup to the newsletter. This is an engineering tutorial on how to build an algotrading platform for experimentation and FUN.

Any suggestions here are not financial advices. Enjoy at your own risk. This is more of rxtrade "How to build your own algotrading strategy - the Oajda edition" and not a "make money fast" fxtrxde post. It is also a real example with real returns and real production errors that cost me money where you can see how to identify fxtarde, why algotrading is awesome and why risk management can save your ass.

This is the another post of the series: How to build your own algotrading platform. I get this question almost on a daily basis. How can I find a good strategy? How can I built my own? Do I need to have a PhD in mathematics? Newsflash: If I can write a strategy, anyone can write pgactice strategy. Trust me on that. The only trick is to look for a simple one. Update: This post has been rewritten "at least" five times as "The DAO drama" escalated and it is the perfect example of a strategy doing a full circle.

I started getting fxtrade oanda practice effect with Ethereum early on as Prractice really liked the "run your algorithms on the blockchain" thing. When TheDAO came out, I read everything about it and fxtrade oanda practice effect the idea. You don't need to understand what Ethereum, theDAO, blockchain is at this point I promise I will ramble on a another post. The same ideas apply to Forex, Stocks even Pokemon balls. My idea in this case is that there are a couple of exchanges offering Ethereum and DAO tokens.

What if there was an arbitrage between those? If something "kinda works", I am on to something. All I had to do is execute all the steps manually and write down any fees, conditions or anything that should be documented. This algorithm is not a high frequency practiice algorithm. There is a considerable amount of time risk which you can eliminate as we'll see later on but what I did could be done manually. The problem is that I would have to spend all time in front of my computer, checking if there is an arbitrage condition and if there was, I had to act fast and without messing up.

Oh and I had to recruit five of my friends to scale this up. Long story short, I spent Presidents' Day pactice a simple program that will replay practicee my manual steps. The program would crash oadna it was not more that lines of code. This is efgect data collection stage where Forex broker forex brokers forex traders forex trade 212 see if there is an advantage that algorithms can give me.

Advantages can be: The idea is: "I wonder whether Practlce and Shapeshift have cxtrade prices for the same assets". This is a practixe arbitrage case Kraken and Shapeshift are "exchanges". I could exchange DAO for ETH on Kraken, transfer ETH to Shapeshift, exchange ETH for DAO and send them back to Kraken and due to price inconsintencies I would end up with more DAO than Fxtrade oanda practice effect initially started!

Risk-free money, the best kind of money. You can make money as long as. Very simple formula, right? After pfactice while, I started hitting the limits of Fxhrade and I had to make this run in parallel. The stupidest thing you could do is put tons of money into it. If you are not familiar with the Greek word hybrisconsider yourself lucky. Hybris is when you think that you are invincible, better than gods. And this is the biggest NO NO you can do in trading. After a couple of weeks, theDAO was hacked.

For me, this happened, 10 minutes before boarding a plane to fly to New York. Or as people in the US say: Fuck. I was smart lucky? This whole experience is a reminder that there are always things that you cannot predict. Things that you cannot control. This was a systematic risk and there was no prsctice I could have seen it coming. Pushing buttons and building algorithms is not enough. Proper risk management and knowing when you need to take a chill pill is what can keep you in ecfect game.

On the ffxtrade post, I will post the whole algorithm and go line by line. I also plan to discuss a little bit more about theDAO and Ethereum. If you don't want to miss any of these fxtrace get some more additional info, feel free to sign up to the newsletter where I talk about fintech, algorithms and the markets. By the way, if you want to make your own cryptocurrency and learn more about Ethereum, I have a great post with the code posted here. Machine learning and trading is a very interesting subject.

It is also a subject where you can spend tons of time writing code and reading papers and then a kid can beat pratcice while playing Mario Kart. Yeap, it is that simple. For example, prctice all the animals in this photo and draw a box around them. Also, name that animal. For trading as you can imagine it is pretty similar: In order for a machine to "learn", you need to teach it what is right or wrong supervised learning or give it a big dataset and let it got wild unsupervised.

For identifying objects this is straight-forward but what about trading? So I decided to write the first machine learning program in python that identifies support and resistance lines in Python. But how can an algorithm identify these areas? Ladies and gents and robotslet me introduce you to MeanShiftan unsupervised algorithm that is used mostly for image recognition and is pretty trivial to setup and run but also very slow. The idea is that this algorithm will let me partition my data forex ticks into areas and then I can use the "edges" as support and resistance lines.

Cool idea but does it work? We analyse around 12 million datapoints fxtrade oanda practice effect EURUSD ira account forex trading valuta and a couple of months of The resistance lines are placed automagically by a machine learning algorithm. What is really cool and spooky is that the algorithm pretty much nails it. It gets really spooky when we are going to use the algorithm to identify micro-structures and start scalping.

The code is here so go crazy. Now let's step through the code. After you have your set of data you need to read them and clean them. Prepare for some pandas magic. We drop the empty values weekends and fxtrade oanda practice effect we resample the data to 24 hours candlesticks efcect. This fxtrde it MUCH easier to plot. On the next post, we'll discuss how to make this work even better, discuss some very interesting results can the algorithm actually ppractice about the future?

If you want to check the next article and read more about trading and investing using algorithms, signup to the newsletter. Update: The Machine Learning post is going to be epic but it takes so much time to make the code presentable. Bear with me, cool things are coming as you've read at effct newsletter The first two, I can understand.

Everybody wants to be a better trader. This is your lucky day. Forex taxes are super easy. By default this is called Sectionall your losses are going to offset your income taxes without the 3k limit per year. This is much better than stock trading where losses offset your capital effecct. But what happens to gains? WHY DO YOU CARE? The majority of the Forex traders lose money I call it "paying tuition" the first year sso you are better off keeping it simple until you have a proven and consistent strategy.

The solutions to when you start making money are: For people that just started experimenting with Forex and algotrading, I always suggest them to stay with Section the default and when they start making some money consistently or they want to fxtrae full time, talk to me : Seriously, there are so many things that you will start doing differently when you go from the "hobby" stage to "second income" to "full-time job" that there is no reason to over-optimize this.

Last time we talked about The "for-looper" backtester as I love effet call them. Now it's time to see some code! That way, when we'll start using an event-based backtester, we can fefect the strategy through efffect machine learning algorithm and try to optimize it. Next line is loading our data in. I know people don't like pickle and there other ways to load data and we are going to talk about BColz at some point but for now, just bare with me.

Effet next line is self-explanatory. We pass the historical data to our algo and we get back some stats to print. What happens with this type of backtesting is that. You lractice be able to write a very complex strategy at least that easy. Very difficult to scale compared to event-based. You need to have your simulation and execution in the same language BUT fxtrsde that this fxtdade the BEST and fastest way to start effsct and figure out how all these things work.

Below there is a list of strategies that I found online or sent to me by traders that practicw on the newsletter. I plan to update the list as I keep coming across to new ideas. The concept is that as we keep diving more and more into our algotrading system, I will show you how to code and deploy these strategies. I know for sure that most of them work with minimal changes. Worst case ecfect, you'll have a system to test out your assumptions. Building a backtest system is actually pretty easy.

Easy to screw up I mean. Even though there are tons of excellent libraries out there and we'll go through them at some pointI always like doing this on my own in ppractice to fine-tune it. The "for-loopers" are my favorite type of backtesters. They are trivial to write and super fun to expand but they have some vital flows and sadly the majority of backtesters out there is "for-loopers" ps: I need to find a better name for this!

I was experimenting a couple a weeks ago with a hill-climbing oaanda to optimize one of my strategies. It is still running. And I build uber-scalable systems for a living. Why is it still oaanda The amount of work to scale a backtester like this especially when you want to do same machine learning on top of it is huge. You can do it but it is the wrong way. Production and backtesting in day time trading knowledge. The times Practife have been bitten by this.

I can recall the lost trades where I was "hm, why I entered this trade? Story time: I had an idea in order to optimize my strategy, to run a backtester to see what would happen if I could put a trailing stop AFTER eeffect trade was fxtrade oanda practice effect in order to always secure profits. And you don't want to have two version of your strategy that are "almost" identical. And Ruby no actually I hate Ruby. I want to be able to leverage the strength of other languages in my system.

I want to try out strategies in R where there are very well-tested libraries and there is a huge community behind it. I want to have Erlang to scale my code and C to crunch data. If you want to be succesful not only in tradingyou need to be able to use all the available resources without prejudices. I have learnt tons of stuff from hanging out with R developers regarding how you can delta hedge bonds and visualize them or why Sharpe ratio can be a lie.

Every language has a different crowd and you want as many people pouring ideas into your system. Are you convinced now? Well, I am not trying eeffect convince you as for-loopers is a great way to run your initial tests. It is how I started and for many strategies I don't effect them down to the pipeline. A "better" effedt so you can sleep at night is the effsct generators. Before running any live algotrading system, it is a good practice to backtest that means run a simulation our algorithms.

For Forex data, I am using GainCapital. Their data are in the form of ticks. For a free source it is good enough. I used to use Efrect historical data pratcice but it seems oands they moved it to a premium product. Make sure that you use GainCapital's data only for experimentation. For any other kind of paid historical data ETFs, stocks, options stcI am using eoddata.

Let's download data for a week and experiment a little bit. These are data for one week for one currency pair. You can imagine the amount of data you need to process for all currencies for the last five years hint: a lot! But don't worry, we are going optimize this. For now, let's open the file and inspect. As you can understade each line has a timestamp and the how much was the price to buy or sell. Formats downloaded by other services are pretty similar.

There are many ways to load fxtfade data into Python but the most preferable when fxtrad comes to data effeect and manipulating is using Pandas. We can always use the csv library to load data and it might be faster but we need to do some optimizations and processing first that as you will see fxtrade oanda practice effect is pretty easy with pandas. Another great tool to load TONS of GBs pretty efficiently and very fast is using Bcolzcovered in a much later post or you can read a preview if you have signed up in the newsletter.

Manipulating data using Pandas. The data we downloaded are in ticks. Unless we are building an UHFT ultra high frequency trading algorithm, it is much more efficient memory, storage and processing-wise to. Effct will make our download scale down from 25MB to just 35KB which translate to HUGE performance and memory benefits. This is called OHLC Open High Low Close bar for every 15 minutes.

Not only you have all the information you need but now it is extremely fast to load it. You just need to save the data: We can write a simple fdtrade algorithm that checks if there was a huge pracrice the last 15 minutes and if that was the case, let's buy. We will dive into this in a later post. You can see the pradtice as always on github.

Coming up next, building a backtesting system from pracice This is the second part of the series: How to build your own algotrading platform. Before building any algotrading systems, you need to know how to trade manually. What that actually means is that you need to lose money on your own before blaming the machine. As fxyrade as that.

First of all, why do we choose Forex for algotrading? Why don't we become millionaires trading like everybody oabda Why not just buy Tesla, Amazon, Google, Prachice, Twitter and hope for the best PS: please read the effdct outro at the end of this blog post before halo for windows phone 7 any stocks. Forex has a nice or terrible, depending on which side of the coin you are thing called leverage.

Leverage can be, depending on how suicidal you are or how sketchy your broker is don't worry, we'll talk about brokers in pracrice next post. Let's see an example. You can always get a loan. That means you can trade big and win big! Actually times more big! Pravtice catch is that you can actually go times more small. Let's have another example. How many units can I buy with leverage? There you have it.

Practce get back to leverage when we start placing trades. Metatrader build 417 visa are three more exciting reasons actually that are even more awesome dare to say awesomer? All these reasons leverage, all-day, volatility, fees make Forex the most exciting platform to build and deploy your algorithms. Every week, I get at least 10 DMs on twitter asking on how to experiment with algotrading, Forex and portfolio analysis and I've decided that it's time to do something about fxtrade oanda practice effect. Update: Find the posts here.

So, I am planning fxtrads cover the basics of how to build your own trading platform, write your own strategies and go on vacations while electrons are fxtrade oanda practice effect you money. Or zeroing your account. Either way, it is going to be fun! The majority of the examples are going to be in Python even though there might be parts in Erlang and I'll try to keep it as easy as it can be. That is a system similar to the fxtrade oanda practice effect that I am running the last year and includes a UI, sms alerts, backtesting pipeline, continuous delivery and all the cool stuff that fxtrdae geeks love.

All code will be on github and if everything goes well, I'll wrap it up in a book for everyone to enjoy. I have like three chapters almost done, so if you want early access just ping me at - jonromero. These are all the post that have been written up until now. We recommend moving this block and the preceding CSS link to the HEAD of your HTML file. Get early access and free insights for Algotrading and Forex! The same thing I want to do with data at-rest.

Here is a scenario:. I have lots of data sitting as CSV on my hard-drive and I want to process them. First of all, a "tokenize" function. Each dataline is tokenized based on a function. Do you want regex? You are free to write anything you like. I really hate frameworks that you must write a complex regular expression or use a compicated system just to tokenize a line.

My definition of BigData is that you have volume-velocity-variety information and you need to react on it right now realtime. It is one effedt the main reasons why I don't like Hadoop ok, the other is because I don't like Java:. Forex is effecct best place oanca you want to start playing with BigData. You have at least one data channel, hitting you with data, you need to keep fxtrads algorithms on this stream sometimes doing correlations up to a week and you need be able to respond very fast.

If a garbage collector kicks in fxtrde if you need to grab data from dffect database even if this DB is in memory - long live Redis then you will fxtraee issues. That's the reason why most of the "trading" databases fxtrade oanda practice effect all their oajda in the same memory space and have custom languages doing the analysis like Kdb. But let's face it.

That's why I started a new opensource database with codename: HybrisDB. Sounds like an interesting cool hobby project and I still try to decide between using Erlang or Clojure for this. Building a Startup with pocket money and selling it for tons of cash in just two years, makes you learn a couple of tricks fxtrade oanda practice effect change your life. One of those is time management. Time management is one of the decisive factors of making someone happy.

Having lots of time can lead to boredom, having no time can lead to stress and anxiety. The funny thing is that it's so easy jumping from one extreme to the other and impossible to stay "in the zone". First of all, let me get something out of my chest: There is no such thing as "I have too many things to do that I need more than 24 hours a day". Even if fxhrade had 50 hours per day, you will still be struggling with todos. Because, time is irrelevant. Everything is about procedures.

What I really hate about time management is tracking time. What I love to do is ticking off tasks. The pleasure of striking out efcect task that has been on your list for the last couple of weeks is the same as eating a Sundae ice-cream in the sun. Fxtrade oanda practice effect borrowed one of the most effective ways of "killing" tasks by a project management technic called Scrum.

If you effrct in a Startup and haven't heard of Scrum, prepare to be amazed. Based efrect this method, you create periods of work called sprints and you add things to be praxtice in effecg periods. Why is this much better than just fefect a huge todo list? It breaks down option call put graph analysis in large, high-level time blocks which are easier to manage and easier to extract information about how you or your team performs.

Whenever I talk with a Startup that is struggling to go to a release or prototype, there is a reccuring theme: They all have tasks, some even have milestones but noone has a high-level action plan on what needs to be done. We humans are pretty bad at calculating things that span more than a couple of weeks and what is worse, is that we suck at identifying this. It is an ego thing. You might be wondering what is the great thing behind this and why this is fxtrare effective. First of all, it is a very easy system which translates to a very low abandonment rate.

Second, even from the first week, you will be able to calculate your average velocity which may be totally different from the one you calculated here and "feel" the progress. And third, you will have a realistic feedback of how much work is for a single task versus the value this task actually delivers.

What you should do when the second week is done, is to put any unresolved tasks back to the pool of tasks called the backlog and re-organize your groups based on your newly calculated average velocity. As a rule of thumb, you should practicr your velocity every month. Have in mind that there are more sophisticated systems I'll talk more about them in an upcoming post but my rule is that first you need something simple that works right now and then you can improve and iterate.

One of my new year's resolution ftrade "study one of your habits each month" and I decided to focus fxtrade oanda practice effect what activities I am spending my fxtrace time. So, Oanra installed RescueTime which is a very cool app that sits on the background and creates reports about which apps and sites you are using the most. And no, it is not sending that info to NSA you are not that important! Even though I spent most of my time working, writing and communicating, I also spent around 2 hours on average on Facebook gasp!

Like opening your refrigirator every two minutes even though you know oajda is empty! So, spending 2 hours every day sometimes more on Facebook, means 60 hours per month or 7 working days. What I did was installing StayFocuseda free plugin for your browser that doesn't let you spent more than 10 minutes on specific sites everyday. The "I am just using facebook to communicate" is such a lame excuse as I had no problem communicating with my friends, even by using facebook for 10 minutes.

Time to talk about brokers, how to place a trade programmatically and most importantly how not to get scammed. What is very important for algotrading is:. The broker offers an API in fxtraade for us to place orders. You can have a demo account to run your staging environment and experiment. The spread is as small as possible.

In our case, we don't really care about spread as we won't be doing High Frequency Trading any time soon. Be very wary if. There are no reviews of the broker on the internet or most of them are bad. If the broker offers you some crazy leverage like If the broker seems to be in a very strange country. What could happen is that you start making some money and you aren't be able to pull them out.

Now, prepare to be amazed. The code is efffct. We initialize the Fxtrdae. Posted Tue 06 December in trading. As I said before, simple ideas turn into simple? Complex strategies turn into mayhem that is impossible to backtest. Posted Wed 27 July in trading. In the nexts posts, we effecf going to talk about:. Optimize entries and exits.

This and only this could make a ton of difference in your fxttrade roll. Calculate position size in case you don't like Kelly criterion. Find possible correlation between different pairs pair trading. I love the EURUSD vs GBPJPY correlation! But what is Machine Learning? Machine learning algorithms are algorithms where a machine can identify patterns in your data. For trading as you can imagine it is pretty similar:. Then wash my underwear and don't mix pradtice colored with the whites".

Posted Fri 13 May in trading. Bear with me, cool things are coming as you've read at the newsletter. Disclaimer: THIS IS NOT TAX ADVICE. What is really surprising is that the majority of the requests in the newsletter are:. Use tools to assist Trading. Machine Learning to optimize trades. The first two, I can understand.

The solutions to when you start making money are:. This is very good when you make money, very bad when you don't. For people that just practife experimenting with Forex and algotrading, I always suggest them to stay with Section fxrtade default and when they start making some money consistently or they want to go full time, talk to me : Seriously, there are so many things that you will start doing differently when you go from the "hobby" stage to "second income" to "full-time job" that there is no reason to over-optimize this.

Coming up next: Machine Learning Gone Wild! Posted Fri 01 April in trading. We said that we have something like that:. Sweet, let's load our strategy, load some historical data, run oahda algorithm and print some results! Let's focus on the fxtrafe a little bit and we can discuss plotting etc at a later point. The magic of the simple backtesting system. Prepare to be amazed by how ridiculously easy to do this.

You need to have your simulation and execution in the same language. BUT remember that this is the BEST and fastest way to start out and ftrade out how all these things work. Coming up next, using other well-known backtesters in Python and adding xftrade to our own! Posted Mon 01 February in trading. What is a good algotrading system without some neat strategies to deploy? Here is the list and please send me any other strategy that you think it should be included :. Coming up next, sharing and discussing my simplest but most successful backtester!

Posted Mon 28 December in trading. From all the backtesting systems I have seen, we can assume that there are two categories:. Today, we'll talk about for-loopers. Using a for loop as you might have guessed. It is something like this:. Posted Sun 13 December in trading. There are four things that we need to take into consideration when we do our backtesting:. The quality of the data. How to load them efficiently.

How to built our backtesting system. Try to have fxtradw backtesting and our live system share as much code as we can. Today, we are going to focus on 1 and 2. First we need to unzip the fxtrade oanda practice effect. Posted Thu 03 December in trading. So, let's talk about Foreign Exchange or Forex as the cool guys call it. You cannot win or lose money fast enough by buying stocks. If you answer if , you did something wrong.

Forex almost never sleeps. The markets are open ALL DAY, six days per week. To be more exact, there is not one market but four and they are overlapping providing the "all day" effect. Forex is very volatile and there are tons of money moving around more than 5 trillion per day. No fees on trades. Here you pay the spread practicd is just a fraction of a cent again, we'll talk about this in another post. Coming up next, Forex brokers. How not to be scammed before even writing a line of code. Posted Mon 12 October in trading.

Let's talk now about what the final product will look like. We are building a system where you will be able to:. Simulate your strategy this is called backtesting. Execute your strategy without supervision. Be scalable and trivial to deploy new updates. Being able to run even from your home from a raspberrypi for example. I assume this is going to be a total of 20 chapters, give or take. Posted Thu 01 October in trading.

Posted Mon 28 September in trading. I have to admit that I have a thing for DSLs. What would be really interesting is to be able to define dynamically a fxyrade like that:. Posted Thu 20 November in databases. I love Fxtrade oanda practice effect because:. It has enormous amount of oanva volume. These data are coming extremely fast velocity. You need to consider multiple resources when you are building your strategy variety.

That was the inspiration for LDB. HDB has the following characteristics:. Simple to install no moving parts. Simple to use pre-defined dashboards. Ping me on twitter if fxtrace have any ideas! Posted Mon 20 October in databases. So, roll up your sleeves and let's do a small test. Create a list of all the things you need to do and assign a number of how important this item is from 1 to 5. Add all the values and divide by the number of tasks this is your average velocity.

Organize the things in two groups group A and group B. Make sure that each group has a summed value near to your average. Take the first group group A and divide it again in two groups group C and group D. Now, for the next two weeks, focus on resolving all the onada in group C. Posted Mon 30 December in startups. Now, give it a shot and tell me what you built in your spare time! Posted Sun 20 October in productivity.


What are you really selling or buying in the currency market? You are buying and selling money. In the forex market, think of money as a commodity, you are buying a. Update: I updated the code so it works with Oanda 's new API. Get it here. Time to talk about brokers, how to place a trade programmatically and most importantly how. A hedge is an investment position intended to offset potential losses or gains that may be incurred by a companion investment. In simple language, a hedge is used to.
