Coding Expert Advisor beginner

[emmatb]

Hi,

I am new to coding in mql4. Can somebody tell me how do you take the variable that tell if the expert advisor will send only short orders, only long orders or both(the one from Common tab)?

Thanks

You check the ordertype...OrderType=OP_SELL or.._BUY

1. There isn't any; the EA's code determines what it "will send." The OrderSend will fail if it isn't allowed that direction however.
   

2. If you meant how to find out the settings, perhaps you should read the manual. MQL5 Reference → Market Info → SymbolInfoInteger → ENUM_SYMBOL_INFO_INTEGER

   Constant	Description	Usage
   SYMBOL_TRADE_MODE_LONGONLY	Allowed only long positions	SymbolInfoInteger
   SYMBOL_TRADE_MODE_SHORTONLY	Allowed only short positions	SymbolInfoInteger

Hi, I already tried this. It seems to show the modes you cand trade on a chart. And the OrderType() is working if you select an order before.
