Read Time: 22 mins Languages:

The world's fiscal markets offer y'all a huge potential for profit and loss. There is always a potential for turn a profit in the market as you can place trades in either direction. Whether your opinion be bullish or surly, the ability for the trader to make money is always present—as is the ability to make a loss.

Far too oftentimes, emotions, psychological mind traps and mental discipline stand up in the way of profits and are the main reasons 95% (or more ) of all new traders lose all their investment capital in the first month.

Using an Expert Advisor algorithm trading robot in Meta Trader written in the MQL4 linguistic communication is i way of accessing the market place via code, thus taking the emotions out of the moving-picture show and working with but the numbers and your program logic.

Taking emotions out of the equation is 1 measure, but this does not mean robots cannot lose. In fact, fifty-fifty the large investment banks have had to pull the plug on their trading robots before the loss became fatal. In 2013, Goldman Sachs had serious faults in their trading algorithms that cost $100 million.

You need to be aware, before continuing with this guide and even contemplating using your real, hard-earned greenbacks, that yous tin lose all your eolith in your brokerage business relationship from your lawmaking (and maybe in worst cases more with some brokers if additional charges apply)

You are responsible ultimately for the trades, fifty-fifty if program code is placing them for you. While loss is a possibility, you can also multiply the account and brand it grow exponentially while you sleep.

If y'all like to run completely on car-airplane pilot, this could be accomplished without any interaction at all. You could literally make money passively whilst you continue with your day-to-24-hour interval life.

This strategy of totally easily-complimentary trading is not 1 I promote—nor is it one I ever utilise and take found profitable at all. Monitoring an agile robot and the current trades, in conjunction with keeping an center on the economic calendar and events, is very different from letting it off wild and hoping for the best. The wins may be ballsy, only the unattended losses far grander.

Installing MQL4

Please download MT4 from their website and install it on your machine.

• Windows users
• macOS users
• Linux users

Once MT4 is running, you lot will need an account with a broker that supports MT4. They will and then be able to give y'all your MT4 login credentials.

All brokers volition offer a demo account, and yous are encouraged to e'er apply the demo account for writing and testing your software.

Once you have configured MT4 on your desktop, nosotros can keep to creating our own Expert Advisor algorithm trading robot.

How to Write a Robot

There are many languages which would exist suitable for writing an algorithm trading robot from scratch, but the complications that you will come across are in fact with the API to direct market place access that your stock broker will provide—that is how you will actually enable yourself to identify the trade orders in the financial markets.

Processing marketplace data could be achieved in a plethora of languages, and probably to a faster extent than the MT4 MQL4 can run back tests (back tests are a way of testing your algorithm robot; more than on this later). For the reasons of ease of functionality and general support for financial software,  I highly recommend using MQL4 (MetaQuotes Language four), the native language of MetaTrader iv, to write your algorithm trading robot.

MQL4's Syntax

MQL4 is similar in its form to PHP, C, C++ or VBScript. Below is an case of a function that will exist called on every tick of market place data:

void OnTick()   {        if(Bars<100 || IsTradeAllowed()==false)           return;        if(CalculateCurrentOrders(Symbol())==0){           CheckForOpen();        } else {           CheckForClose();        }   }

Here we check if there has been enough market data loaded with Bars < 100. MQL4 sets predefined variables such as Confined (which contains the number of bars loaded into the nautical chart).

Additionally, we bank check with an or|| provisional for IsTradeAllowed(). This is a check part to check that the trading context is non currently busy.

Elements of MQL4 such as these predefined variables and chart operation functions like Symbol() make writing your strategy a walk in the park, and for me are why it is actually preferable to code algorithm trading robots in MQL4 over other languages.

I recommend y'all have a look through the MQL4 Reference whenever you accept fourth dimension to go more confident in using MQL4 to further satisfy your needs.

Editing MQL4 Code in the MetaEditor

I recommend using the built-in MetaEditor IDE that comes with the MT4 trading platform. To enter the editor, just right-click on an existing expert advisor in the left-hand navigator pane and select modify from the card.

The MetaEditor of MT4 will then open up, and you will be able to create a new file. This offers the user syntax highlighting and debugging output.

Important: You will have to compile your mq4 files into ex4 practiced advisors using the MetaEditor if you are editing in an external editor. Then getting familiar with the MetaEditor is a must.

Our Algorithm

For our strategy, we will begin using a basis of support and resistance from theSMA (Smoothed Goving Average) indicator. The SMA tin predict a bullish or surly entry/exit indicate. The smoothed moving average helps united states cutting out the noise from the market, giving us a clearer view of the direction of the price action.

In either an uptrend or downtrend, the SMA can behave every bit a support or resistance, depending on the orientation. When the toll is going upward, the SMA will behave as a flooring of support, and when the price is declining, vice versa equally a resistance/ceiling.

Ground for Entry

When we plot two SMAs of unlike periods—i of a 40 period and one of a 100 period—we can and so see how they cantankerous over and create a basis for entry. As we mentioned before, when the SMA is beneath the price (less than the close cost), we consider information technology a footing for support, and when the SMA is above the price (greater than the close price), we consider this a line of resistance.

So, in code, nosotros do the following first to create a method for checking the cantankerous-over of inputs for later determining our footing for entry:

//+------------------------------------------------------------------+ //| Check for cross over of inputs                                      | //+------------------------------------------------------------------+ int CheckForCross(double input1, double input2) {   static int previous_direction = 0;   static int current_dirction = 0;    // Up Direction = one   if(input1 > input2){     current_direction = one;   }    // Downwards Management = 2   if(input1 < input2){     current_direction = 2;   }    // Detect a management alter   if(current_direction != previous_direction){     previous_direction = current_dirction;     return (previous_direction);   } else {     return (0);   } }        

Now we tin can calculate our SMA using the iMA technical indicator method provided past MQL4 and run that through our CheckForCross function to see if there has been a cantankerous like and so:

shortSma = iMA(Nada, 0, PeriodOne, 0, MODE_SMMA, PRICE_CLOSE, 0); longSma = iMA(Null, 0, PeriodTwo, 0, MODE_SMMA, PRICE_CLOSE, 0);  // Check if at that place has been a cross on this tick from the two SMAs int isCrossed = CheckForCross(shortSma, longSma);        

Here we are using the MODE_SMMA to render us the Southmoothed Moving Average from the iMA technical indicator method for our chosen smoothing method.

If you lot wish to use another smoothing method, at that place are several choices such as Unproblematic, Exponential, and Linear-weighted.

Every bit with all support and resistance, the standard trading methodology works hither:buy back up and sell resistance!

So, for our algorithm, we are going to do merely that. When there is a cross in either management, we are going to use the appropriate management of merchandise and enter the marketplace.

f(isCrossed == 1){         ticket = OrderSend(Symbol(),OP_BUY, LotsOptimized(),Ask,3,0,0,"Double SMA Crossover",MAGICNUM,0,Bluish);         if(ticket > 0){           if(OrderSelect(ticket, SELECT_BY_TICKET, MODE_TRADES))             Print("BUY Club Opened: ", OrderOpenPrice());           }           else             Print("Error Opening BUY Order: ", GetLastError());             return(0);         }     if(isCrossed == ii){       ticket = OrderSend(Symbol(),OP_SELL, LotsOptimized(),Ask,three,0,0,"Double SMA Crossover",MAGICNUM,0,Blue);       if(ticket > 0){         if(OrderSelect(ticket, SELECT_BY_TICKET, MODE_TRADES))           Print("SELL Order Opened: ", OrderOpenPrice());         }         else           Print("Error Opening SELL Society: ", GetLastError());           return(0);       }     }

Here nosotros cheque for the return of theCheckForCross function nosotros defined prior, after loading it with our two SMAs defined by theiMA technical indicator.

Nosotros use OrderSend, which is provided by MQL4, to open the trade. Equally a all-time practice, the result is stored in the ticket variable and later checked for a positive render value and so equally to handle whatever fault that may accept been reported from the broker's side.

Basis for Leave

Like the ground for entry (except in the inverse case), when the SMA creates a decease cantankerous, we tin use this signal for closure of our trade, if any trades are open. The logic for this would be written equally so:

// Get the current total orders   total = OrdersTotal();    // Manage open orders for exit criteria   for(cnt = 0; cnt < total; cnt++){     OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES);     if(OrderType() <= OP_SELL && OrderSymbol() == Symbol()){       // Look for long positions       if(OrderType()==OP_BUY){         // Bank check for Go out criteria on buy - alter of direction         if(isCrossed == 2){           OrderClose(OrderTicket(), OrderLots(), Bid, iii, Violet); // Shut the position           render(0);         }       }       else //Look for curt positions - inverse of prior conditions       {         // Check for Exit criteria on sell - modify of direction         if(isCrossed == 1){           OrderClose(OrderTicket(), OrderLots(), Ask, 3, Violet); // Close the position           render(0);         }       }     }   }

Here we enter a for loop to iterate over all the open orders, although currently we volition simply trade one merchandise at a time—this allows u.s.a. to expand in the future and have multiple open up trades if we feel we need it.

This also makes usage of the OrderSelect method easier, as nosotros tin employ the cnt variable from our for loop.

Once inside the iteration, nosotros simply await at the current OrderType (checking for a Buy OP_BUY or Sell OP_SELLorder) and and then apply the conditional logic from the render of our CheckForCross method.

Adding Money Management

Right now our algorithm is simple with a basis for entry and exiting of trades, just still quite dangerously stupid when it comes to fund management. For us to keep the risk under some control, we will only place ane-fifth of the tradable equity on each merchandise, then now we need to factor that into our algorithm.

lot = NormalizeDouble((AccountFreeMargin()/5)/k.0,1); if(lot<0.1) lot=0.ane; return(lot);

This means if you lot accept $ten,000 in the business relationship, nosotros just trade with one-fifth at a time ($2,000), so the script will but identify a merchandise with a smaller size lot of 0.i or 0.ii, for instance—based on this one-5th calculation.

Nosotros apply AccountFreeMargin and NormalizeDouble to generate this lot size, and if it's calculated at below the minimal lot size of 0.ane, we will prepare it to 0.1.

As the account grows (or shrinks!), the exposure is but going to exist prepare at one-fifth of the account equity. This means that over-exposure of a fixed amount (east.grand. trading a specific fixed lot on any size business relationship) theoretically cannot happen, ergo the hazard of margin call from over-trading is removed or profoundly reduced.

Margin call is a very existent risk if the market moves confronting you drastically before returning due to a spike/fluctuation whilst you are not around to deposit more funds.

In layman's terms, the lot size of the trade will be calculated dynamically by our script to meet the equity size. So the potential for larger and larger profits is very real.

Note: A dainty feature could be to provide a parameter to cap the tradable puddle. For example, if you wished simply to ever trade with $1,000 of your business relationship, regardless of the available margin, yous could set the bachelor tradable to just $one,000 rather than your whole account size.

Personally I always use features like this when going live with new scripts in gild to reduce my exposure to risk, until I am really certain the script is functioning solidly plenty to be immune more funds.

Programmatically, this requires a parameter and a slight modify to the code example in a higher place to check for that variable rather than the AccountFreeMargin() value.

Break Even

Additionally, we will try to perform some break-fifty-fifty situations, meaning that if the marketplace has changed against the states to create a loss essentially from opening, nosotros look to exit with minimal loss and at least break even so as to retain our capital.

This can be achieved by monitoring the loss of our trade and relation to the open cost. If the direction changes and our trade is left out of the money, we can attempt to close out the trade as close to the entry cost equally possible:

          bool BreakEven(int MN){     int Ticket;      for(int i = OrdersTotal() - 1; i >= 0; i--) {       OrderSelect(i, SELECT_BY_POS, MODE_TRADES);        if(OrderSymbol() == Symbol() && OrderMagicNumber() == MN){         Ticket = OrderModify(OrderTicket(), OrderOpenPrice(), OrderOpenPrice(), OrderTakeProfit(), 0, Green);         if(Ticket < 0) Print("Error in Suspension Even : ", GetLastError());           break;         }       }      render(Ticket); }

The above uses OrderModify to attempt to prepare the finish loss to the lodge open price. This is a crude merely uncomplicated method to ensure that we step out when the cost comes dorsum to our entry cost. This is merely applied when the current unrealised profit is in a loss.

Calculation a Break-Even Margin

A margin for break-even could exist added by simply adding to the OrderOpenPrice method like and so:

Ticket = OrderModify(OrderTicket(), OrderOpenPrice(), OrderOpenPrice()+ten, OrderTakeProfit(), 0, Greenish);

For this instance, we let 10 points divergence in our entry to closure via stop limit.

Note: Management of trade should be checked for this method—as in whether it should be added to or subtracted from the entry cost according to whether it is a buy or sell position.

Another way to ensure our gains are not lost is to use a trailing stop, which will exist discussed in detail in some other guide.

The Whole Script

Here is the total listing for our adept advisor. Nosotros have several parameters available at our disposal such every bit the accept profit level, cease loss, and the SMA periods.

Please feel free to play with the parameters to run across what is working best for your trading situation and fine melody your algorithm.

Remember: by performance is in no way indicative of the future.

Testing It Out

Nosotros can exam the previous days, months, or even years of market data for a fiscal instrument with ease in the MT4 (Meta Trader 4) environs. Withal, traders are encouraged non to trust back testingalone, but to use information technology every bit a guide to steer their trading strategy and see how constructive an idea is.

Back testing enables traders to bank check if their thinking holds water, so to speak, before committing more endeavour and moving forrard—writing more than of their algorithm into code.

Where to Place the Good Files?

If you lot take been using an external text editor to write your counselor, you lot will need to load your skillful advisor into MT4 trading platform to compile information technology and fault check. Merely add the .mq4 file to your MetaTrader installation in the Expert directory, e.g./MetaTrader4/MQL4/Experts.

The Proficient Advisor will then be available inside your MT4 software from the Navigator menu on the left-hand side under the experts section.

Note: Brand sure you are testing on a demo account. A real business relationship volition trade with real money, and although the profits will be real, so volition the losses.

Back Testing

If you tested a strategy on the final year of cable (GBP/USD) and found the profit ratio to exist above one (pregnant yous fabricated money), and so you could be onto a proficient affair.

Whether this volition piece of work out in the real earth is a whole other question, and is why forrard testing is equally important, as is Z score testing. That's a much more than advanced topic for machine learning your algorithm, which will not be discussed here, only in afterward more advanced guides.

How to Start a Back Exam

Use the shortcut Command-R to open the Strategy Tester or select information technology from the View menu. The tester pane will open in the bottom of your window.

From here, yous tin select the algorithm to run in the beginning dropdown bill of fare, so choose the filename of the Expert advisor yous have created here. Next, you tin cull the symbol (fiscal instrument). I will be testing on the forex GBPUSD symbol of the British Pound to U.s.a. Dollar pair.

Nosotros tin also select the time period resolution to run on (xv-minute menses, ane-hour menstruum, 1-day period, and so on). I will be using the 30-minute setting.

Finally, we take an option for modelling on Every Tick, Control Points, or Open Prices simply. While writing your script, you can opt for the Open Prices only, equally information technology will rapidly execute your test—although the results won't exist worth banking existent money on nonetheless!

For this, when you are looking for a real test before going to frontward testing, it is recommended to run on Every Tick. This volition take a lot longer to procedure! (You can leave it running in an MT4 VPN online or of course overnight on your local car if you wish.)

Modifying the Parameters

We set a couple parameters (PeriodOne and PeriodTwo) for our good counselor and then that the time periods of the ii Moving Averages can exist modified.

These tin exist accessed via the Strategy tester by clicking the Adept Properties push button and viewing the input tab.

A numerical value can be given for each parameter here—the defaults are PeriodOne= 40 and PeriodTwo = 100.

Frontward Testing

Once y'all have tested over historical data, you tin can start to examination with the live market every bit you have already seen if your ideas weathered the tempest from the back test—and (hopefully) have constitute some conviction in what you believe to be a winning strategy!

In the live market, y'all may find your strategy falls apartment on its face due to elements you had not factored in your prior back tests. Recall the market place is ever correct. Your code is never smarter than the market place, and there is no such thing as beingness lucky in trading.

A forward test really is the acid examination to see if the strategy will be profitable for you to put real money on information technology.

The forward test is usually best performed on a dedicated VPN for MT4 EA (Expert Advisors) which is often provided gratis by near FX brokers. The script will run 24/5 whilst the market is open, and you will exist able to monitor the trades live by logging in to the business relationship from a concluding as it will run on your mobile device via the MT4 app—or desktop auto via the MT4 software.

High Volatility

What can exist a existent killer to our scripts is high volatility in the market place, which can occur from many exterior factors.

For example, whatever crash or flash crash, war, ballot, interest rate hike, bond yields or significant economic study such as the CPI, Gdp or changes to the tax system are going to cause big changes throughout the global economy and its many financial markets. So likewise, indirectly, your trade in i currency pair or security can be affected past some other land's events, which y'all may not have anticipated at first.

Most recently, Brexit and later Hillary Clinton's FBI investigation during the run-upwards to the US elections were examples of high volatility in the market place for anyone interested in taking a closer expect.

Allow'southward take the instance of Brexit. The British public seemed to believe in the majority that a Brexit vote would exist highly unlikely. I was not and then optimistic and pulled all my pounds out, saving a lot of my equity in the Uk due to the plummeting exchange rate.

Equally for others, I'm agape to say they were not so lucky. Hedging on a stay vote—as some of the major banks' advisors had stated—would of course accept resulted in the inverse, and a loss of approximately 15% to those vested in the pound, as they wait for information technology to recover.

Situations like this are platonic to turn off your trading robot and merely trade exterior of high market volatility. Coding for this kind of outcome is going to exist very hard automatically going on leading or lagging indicators and is better traded after the outcome or manually. The chances for false or contradictory signals are e'er higher during big events, and a manual cardinal approach rather than a technical one may be more than profitable.

At that place is zero wrong with pausing your robot because y'all are expecting a crisis. It may relieve you a loss, whilst on the other manus it may make you lot miss out on a huge win. In my experience, the chances of the win are far slimmer, due to the sheer uncertainty and likelihood of margin telephone call or hitting your stop loss before the trade tin progress due to farthermost momentary spikes.

Conclusions

We've laid downwardly some of the basics of writing a trading algorithm and introduced many new ideas. From walking through the code, I hope y'all can now see the inner workings of an algorithm in MQL4, and see how a technical indicator like the moving boilerplate is used for generating an entry and exit signal.
