As yous may know, the Foreign Substitution (Forex, or FX) market place is used for trading between currency pairs. Simply you lot might non exist aware that it's the most liquid market place in the world.

A few years ago, driven by my curiosity, I took my first steps into the world of Forex algorithmic trading by creating a demo account and playing out simulations (with fake money) on the Meta Trader iv trading platform.

Afterward a calendar week of 'trading', I'd most doubled my money. Spurred on by my own successful algorithmic trading, I dug deeper and eventually signed upward for a number of FX forums. Soon, I was spending hours reading nigh algorithmic trading systems (dominion sets that make up one's mind whether you should purchase or sell), custom indicators, market moods, and more.

My Start Client

Around this fourth dimension, coincidentally, I heard that someone was trying to find a software developer to automate a elementary trading arrangement. This was back in my college days when I was learning about concurrent programming in Java (threads, semaphores, and all that junk). I idea that this automated arrangement this couldn't be much more complicated than my advanced data science course piece of work, so I inquired about the job and came on-board.

The client wanted algorithmic trading software congenital with MQL4, a functional programming linguistic communication used by the Meta Trader iv platform for performing stock-related actions.

MQL5 has since been released. As you might wait, it addresses some of MQL4's issues and comes with more congenital-in functions, which makes life easier.

The part of the trading platform (Meta Trader 4, in this case) is to provide a connection to a Forex broker. The broker and so provides a platform with real-time information about the market and executes your purchase/sell orders. For readers unfamiliar with Forex trading, hither's the information that is provided past the data feed:

This diagram demonstrates the data involved in Forex algorithmic trading.

Through Meta Trader 4, you can admission all this information with internal functions, accessible in diverse timeframes: every infinitesimal (M1), every five minutes (M5), M15, M30, every hour (H1), H4, D1, W1, MN.

The motion of the Current Price is called a tick. In other words, a tick is a alter in the Bid or Enquire cost for a currency pair. During agile markets, there may be numerous ticks per 2d. During boring markets, there tin exist minutes without a tick. The tick is the heartbeat of a currency market robot.

When you place an club through such a platform, you buy or sell a certain volume of a sure currency. Yous also set stop-loss and take-profit limits. The finish-loss limit is the maximum corporeality of pips (cost variations) that you can beget to lose before giving up on a trade. The take-turn a profit limit is the amount of pips that you lot'll accumulate in your favor before cashing out.

If you desire to learn more nearly the basics of trading (e.g., pips, order types, spread, slippage, market orders, and more), run across here.

The client's algorithmic trading specifications were simple: they wanted a Forex robot based on two indicators. For groundwork, indicators are very helpful when trying to define a marketplace state and make trading decisions, equally they're based on past data (e.k., highest price value in the last n days). Many come built-in to Meta Trader 4. Nevertheless, the indicators that my client was interested in came from a custom trading organization.

They wanted to trade every time two of these custom indicators intersected, and simply at a certain angle.

This trading algorithm example demonstrates my client's requirements.

Easily On

Equally I got my easily dirty, I learned that MQL4 programs take the following structure:

[Preprocessor Directives]
[External Parameters]
[Global Variables]
[Init Function]
[Deinit Function]
[First Function]
[Custom Functions]

The start function is the heart of every MQL4 program since it is executed every fourth dimension the market moves (ergo, this function will execute once per tick). This is the case regardless of the timeframe you're using. For instance, you could be operating on the H1 (one 60 minutes) timeframe, yet the beginning function would execute many thousands of times per timeframe.

To piece of work effectually this, I forced the function to execute once per period unit of measurement:

          int starting time() {  if(currentTimeStamp == Time[0]) return (0);        currentTimeStamp  = Time[0];  ...

Getting the values of the indicators:

          // Loading the custom indicator extern string indName = "SonicR Solid Dragon-Trend (White)"; double dragon_min; double dragon_max; double dragon; double trend; int start() {   …   // Updating the variables that hold indicator values   actInfoIndicadores();  …. string actInfoIndicadores() {       dragon_max=iCustom(NULL, 0, indName, 0, ane);     dragon_min=iCustom(Zilch, 0, indName, ane, 1);     dragon=iCustom(NULL, 0, indName, four, one);     tendency=iCustom(NULL, 0, indName, 5, ane); }

The decision logic, including intersection of the indicators and their angles:

          int outset() { …    if(ticket==0)     {            if (dragon_min > trend && (ordAbierta== "OP_SELL" || primeraOP == true) && anguloCorrecto("BUY") == truthful && DiffPrecioActual("BUY")== true ) {             primeraOP =  false;             abrirOrden("OP_BUY", false);          }          if (dragon_max < trend && (ordAbierta== "OP_BUY" || primeraOP == truthful) && anguloCorrecto("SELL") == true && DiffPrecioActual("SELL")== truthful ) {             primeraOP = false;             abrirOrden("OP_SELL", simulated);          }      }         else    {               if(OrderSelect(ticket,SELECT_BY_TICKET)==true)        {            datetime ctm=OrderCloseTime();            if (ctm>0) {                ticket=0;               return(0);            }        }        else           Print("OrderSelect failed fault code is",GetLastError());         if (ordAbierta == "OP_BUY"  && dragon_min <= trend  ) cerrarOrden(fake);        else if (ordAbierta == "OP_SELL" && dragon_max >= tendency ) cerrarOrden(false);    } }

Sending the orders:

          void abrirOrden(cord tipoOrden, bool log) {      RefreshRates();    double volumen = AccountBalance() * indicate;     double pip     = point * pipAPer;       double ticket  = 0;    while( ticket <= 0)    {  if (tipoOrden == "OP_BUY")   ticket=OrderSend(simbolo, OP_BUY,  volumen, Ask, 3, 0/*Bid - (point * 100)*/, Inquire + (point * 50), "Orden Buy" , 16384, 0, Green);       if (tipoOrden == "OP_SELL")  ticket=OrderSend(simbolo, OP_SELL, volumen, Bid, 3, 0/*Enquire + (indicate * 100)*/, Bid - (bespeak * 50), "Orden Sell", 16385, 0, Red);       if (ticket<=0)               Impress("Mistake abriendo orden de ", tipoOrden , " : ", ErrorDescription( GetLastError() ) );     }  ordAbierta = tipoOrden;        if (log==true) mostrarOrden(); }

If you're interested, you can find the complete, runnable code on GitHub.

Backtesting

Once I built my algorithmic trading system, I wanted to know: 1) if information technology was behaving appropriately, and 2) if the Forex trading strategy it used was any practiced.

Backtesting (sometimes written "dorsum-testing") is the process of testing a particular (automated or not) system nether the events of the past. In other words, you test your system using the by as a proxy for the nowadays.

MT4 comes with an adequate tool for backtesting a Forex trading strategy (present, there are more than professional tools that offer greater functionality). To start, you setup your timeframes and run your plan under a simulation; the tool will simulate each tick knowing that for each unit it should open at certain toll, shut at a certain price and, accomplish specified highs and lows.

After comparing the actions of the program against historic prices, you lot'll accept a good sense for whether or not information technology's executing correctly.

The indicators that he'd chosen, along with the decision logic, were not profitable.

From backtesting, I'd checked out the FX robot's render ratio for some random time intervals; needless to say, I knew that my client wasn't going to become rich with it—the indicators that he'd chosen, along with the decision logic, were non profitable. Equally a sample, hither are the results of running the programme over the M15 window for 164 operations:

These are the results of running the trading algorithm software program I'd developed.

Notation that our balance (the blue line) finishes below its starting point.

One caveat: saying that a system is "profitable" or "unprofitable" isn't always genuine. Often, systems are (un)assisting for periods of time based on the marketplace's "mood," which can follow a number of chart patterns:

A few trends in our algorithmic trading example.

Parameter Optimization, and its Lies

Although backtesting had made me wary of this FX robot's usefulness, I was intrigued when I started playing effectually with its external parameters and noticed large differences in the overall Render Ratio. This item science is known every bit Parameter Optimization.

I did some rough testing to try and infer the significance of the external parameters on the Render Ratio and came upwards with something similar this:

One aspect of a Forex algorithm is Return Ratio.

Or, cleaned upwardly:

The algorithmic trading Return Ratio could look like this when cleaned up.

You lot may think (equally I did) that you should use the Parameter A. Just the determination isn't every bit straightforward as it may appear. Specifically, notation the unpredictability of Parameter A: for pocket-size error values, its return changes dramatically. In other words, Parameter A is very likely to over-predict time to come results since any incertitude, any shift at all will event in worse performance.

But indeed, the futurity is uncertain! And and so the render of Parameter A is also uncertain. The best choice, in fact, is to rely on unpredictability. Oftentimes, a parameter with a lower maximum return but superior predictability (less fluctuation) will exist preferable to a parameter with loftier return but poor predictability.

The only thing you lot can exist sure is that yous don't know the future of the market, and thinking you know how the market is going to perform based on past data is a error. In plough, you must acknowledge this unpredictability in your Forex predictions.

Thinking yous know how the market is going to perform based on past data is a error.

This does not necessarily mean we should use Parameter B, because even the lower returns of Parameter A performs improve than Parameter B; this is merely to bear witness you that Optimizing Parameters can event in tests that overstate likely time to come results, and such thinking is non obvious.

Overall Forex Algorithmic Trading Considerations

Since that commencement algorithmic Forex trading experience, I've congenital several automated trading systems for clients, and I can tell you that there'due south always room to explore and further Forex assay to exist done. For case, I recently congenital a system based on finding and so-called "Big Fish" movements; that is, huge pips variations in tiny, tiny units of fourth dimension. This is a subject that fascinates me.

Building your ain FX simulation system is an first-class option to larn more than about Forex market trading, and the possibilities are endless. For example, y'all could try to decipher the probability distribution of the price variations every bit a office of volatility in ane market (EUR/USD for example), and maybe make a Monte Carlo simulation model using the distribution per volatility country, using any caste of accuracy you desire. I'll leave this as an do for the eager reader.

The Forex globe tin can exist overwhelming at times, only I hope that this write-upwards has given y'all some points on how to start on your own Forex trading strategy.
