Constant information monitoring, knowledge evaluation, patterns and value change monitoring are a part of a dealer’s routine that takes a very long time, focus, and far effort. This is difficult even for knowledgeable merchants.
To maximize income, merchants ought to react rapidly, be mentally agile, and management feelings. Even easy fatigue can result in buying and selling losses. So automation of market evaluation and knowledge assortment is an effective strategy to save time and nerves and keep away from human mistake components. Traders who use automated programs and algorithms are known as algo merchants.
What and why to automate?
Any course of might be automated, from knowledge assortment and evaluation to the most recent occasions notifications (for instance, by way of Telegram). Process automation permits merchants to keep away from human errors, spend extra time for themselves or household, calm down, and get better.
How to start out?
The MetaTrader platform supplies the MQL programming language to automate most buying and selling processes. Thanks to this specifically tailored language, even freshmen in programming can use the entire vary of MetaTrader instruments, from getting indicator indicators to totally automated buying and selling based mostly on their algorithm.
The MQL4 and MQL5 languages equivalent to MetaTrader 4 and MetaTrader 5 differ from one another. For newbies in programming, it is higher to start out with MQL4 as a result of you may even write a easy buying and selling robotic (EA – skilled advisor) utilizing this language. By the best way, we advocate visiting the web site web page [https://www.mql5.com/] to search out extra articles, scripts, and different supplies about algo buying and selling and ask like-minded individuals any questions on the discussion board.
MQL4 is straightforward
We’ll show the simplicity of working with MQL4 by describing a easy robotic (EA) in MQL4.
First, open an account with any of the brokers. We advise the FBS dealer and their website FBS.com as a consequence of its worldwide licenses, good repute, and favorable circumstances for algo merchants. When your account is opened, log in to it by way of MT4.
Open MT4 Trading Platform and comply with these steps: In the Navigator window, discover the Expert Advisor part, right-click, and choose Create in MetaEditor. Next, choose Expert Advisor (template) – Next – Specify a reputation (ExpertFirstEA, and many others.) – Next – Next – Done. The MetaEditor code editor window will open.
Below is a full itemizing of this system, which you’ll copy into MetaEditor and click on Compile. You will see that your EA named FirstEA (and many others.) has appeared within the Expert Advisors part.

Try to start out your EA in your account by transferring it to the chart. You additionally must activate the AutoTrading button (on the prime of MT4) and permit automated buying and selling within the Tools – Options – Expert Advisors – Allow automated buying and selling settings.
Now, if the worth of the RSI (Relative Strength Index) indicator is beneath 30, a Buy order with a quantity of 0.01 is opened, whereas an opened Sell order is closed. If the indicator worth is above 70, a Sell order with a quantity of 0.01 is opened, whereas an opened Buy order is closed. That’s it! We launched a buying and selling robotic based mostly on the values of the RSI indicator.
What does a code imply?
Let’s perceive the code’s construction. The code consists of 1 predominant operate and several other auxiliary features.
The predominant operate is OnTick() which executes its code (inside curly braces) each tick. A tick is an occasion when the instrument value course adjustments. OnTick() is the primary operate the place different features are known as to assist carry out particular actions, comparable to closing and counting opened Sell and Buy orders.
Auxiliary features are:
CloseSell() – closes all Sell orders
CloseBuy() – closes all Buy orders
QuantitySell()- counts all Sell orders
QuantityBuy()- counts all Buy orders
Imagine your TV is damaged, and also you name a specialist to repair it as a result of you do not know the TV mechanisms, however a specialist is aware of every little thing about fixing the machine. It means this specialist serves a selected operate for you – a TV restore. Similarly, the primary operate calls OnTick() auxiliary features to carry out sure actions.
if(iRSI(NULL,0,14,PRICE_CLOSE,0)>=70 && QuantitySell()==0)
The above code actually means the next: if the worth of the RSI indicator is larger than or equal to 70 and the variety of opened Sell orders is 0. To keep away from opening multiple Sell order, we name for the “QuantitySell” operate, which solely counts the variety of opened Sell orders.
Then we examine if there are open Buy orders, and if there are (larger than 0), then we shut them:
if (QuantityBuy()>0) CloseBuy()
Here, we name the CloseBuy() operate that helps us to shut Buy orders. This operate solely performs the closing Buy orders, nothing else.
Then, we open a Sell order:
OrderSend(Symbol(),1,0.01,Bid,0,0,0,””,0,0,0);
Similarly, we write a situation for opening a Buy order:
if(iRSI(NULL,0,14,PRICE_CLOSE,0)<=30 &&=”” QuantityBuy()=”=0)
The above situation equally checks the worth of the RSI indicator, and whether it is lower than 30, then Sell orders are closed and Buy orders are opened, i.e., actions described in curly brackets beneath.
It’s not that onerous, is it?
