Monitoring an active robot and the current trades, in conjunction with keeping an eye on the economic calendar and events, is very different from letting it off wild and hoping for the best. The wins may be epic, but the unattended losses far grander.

Please download MT4 from their website and install it on your machine. Once MT4 is running, you will need an account with a broker that supports MT4. They will then be able to give you your MT4 login credentials.Īll brokers will offer a demo account, and you are encouraged to always use the demo account for writing and testing your software. Once you have configured MT4 on your desktop, we can continue to creating our own Expert Advisor algorithm trading robot. There are many languages which would be suitable for writing an algorithm trading robot from scratch, but the complications that you will encounter are in fact with the API to direct market access that your stock broker will provide-that is how you will actually enable yourself to place the trade orders in the financial markets. Processing market 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 on this later). For the reasons of ease of functionality and general support for financial software, I highly recommend using MQL4 (MetaQuotes Language 4), the native language of MetaTrader 4, to write your algorithm trading robot.

Print('Error Opening SELL Order: ', GetLastError()) Print('SELL Order Opened: ', OrderOpenPrice()) Ticket = OrderSend(Symbol(),OP_SELL, LotsOptimized(),Ask,3,0,0,'Double SMA Crossover',MAGICNUM,0,Blue) Print('Error Opening BUY Order: ', GetLastError()) Print('BUY Order Opened: ', OrderOpenPrice()) If(OrderSelect(ticket, SELECT_BY_TICKET, MODE_TRADES)) Below is an example of a function that will be called on every tick of market data: void OnTick() MQL4 is similar in its form to PHP, C, C++ or VBScript. Here we check for the return of the CheckForCross function we defined prior, after loading it with our two SMAs defined by the iMA technical indicator. We use OrderSend, which is provided by MQL4, to open the trade.
