Trade two currency pairs simultaneously

[jxlibin1987]

When I need to "buy EURUSD", I also need to "sell GBPUSD". Similarly, when closing the position of EURUSD, the position of GBPUSD will also be closed. What I need is to open and close these two positions simultaneously. How can I do this? When backtesting historical data, it has no effect. Why?

Hello,
Since the pairs trading backtest isn't working properly for you, I assume you are using MT4. MT4 doesn't support this.
You should use MT5 for pairs trading. Generally speaking, you can enter the symbol EURUSD for the "Buy" block and the symbol GBPUSD for the "Short" block.
