New comment
 
In strategy testing, after the order has reached SL, then an opposite order is created, can this be prevented?

That is not an issue with the Strategy Tester. That is an issue with the EA, the MQL program you are testing — you will need to fix the EA's logic and code.

Thank you 

How to fix?

trade.Buy(volume,Symbol(),0,SL,0)

A single line of code will not fix the issue. You need to analyse your entire code logic and correct it.

Think about your code logic!

  • What will happen when your position hits the stop-loss or the take-profit?
  • It will close, and what do you think "PositionsTotal()" will then return?
  • It will return zero, and what do you think your code will do?
  • It will place another trade!

Programming is about thinking in logical sequencial steps!

I know that

My problem is after position close

The order is closed by a Sell order and thus I receive 2 orders and 2 deals for each order I opened and I want to prevent this.

Yes, that is normal. That is how orders, positions and deals work in MT5.

Orders, Positions and Deals in MetaTrader 5

MetaQuotes, 2011.02.01 16:13

Creating a robust trading robot cannot be done without an understanding of the mechanisms of the MetaTrader 5 trading system. The client terminal receives the information about the positions, orders, and deals from the trading server. To handle this data properly using the MQL5, it's necessary to have a good understanding of the interaction between the MQL5-program and the client terminal.

I understand that, but when I open an order live in MT5 and not through MQL, then there is no such thing

Yes, there is. In your trade "History" tab, enable the "Orders & Deals" view (instead of "Positions" view) and you will see.

When you place a "buy" order and a "buy" position is opened, there is a "buy/in" deal for it. And when it hits one of the stops, then there is another "sell" order and a "sell/out" deal for that too.

The opening deal is called the "in" deal, and the closing deal is called the "out" deal.

Now I understand your question more clearly.

You were not referring to the EA placing a opposite position, you were referring to the reverse order/deal that accompanies the closing of a position.

That is how it works. To close a position, there is always a "out" order/deal to close it, just as there is a "in" order/deal to open it.
