This EA was generated by the mt5 editor. So I don't know how to add buy/sell here. To be more precise, I placed a header at the top of the code, but then I don't know what to do with it.

Now where to insert:if(inp_direction!=DIRECTION_SELL)if(inp_direction!=DIRECTION_BUY

Ok, thanks!
 
Can you tell me how to find the minimum OrderOpenPrice from the OP_SELL grid?
 
makssub find the minimum OrderOpenPrice from the OP_SELL grid.

as well as the distance, but compare the opening price.

Write an example, because I'm already a bit confused. If it's not too much trouble. Thanks
