Order expiration

New comment
 

Hey guys i would aappreciate if you help.

Can someone tell me why my orders are not expirng?



if((Buy_Sell_Signal()=="Buy") && (OrdersTotal() == 0)) Ticket = OrderSend(NULL,ORDER_TYPE_BUY_LIMIT,Lot_Size,(iBands(NULL,0,BB_Period,BB_Deviation2,BB_Shift,BB_Applied_Price,2,0)),0,0,0,"Opened Bolliger Band EA",MN,0);

if((Buy_Sell_Signal()=="Sell") && (OrdersTotal() == 0)) Ticket = OrderSend(NULL,ORDER_TYPE_SELL_LIMIT,Lot_Size,(iBands(NULL,0,BB_Period,BB_Deviation2,BB_Shift,BB_Applied_Price,1,0)),0,0,0,"Opened Bolliger Band EA",MN,0);
  
 

  1. Be careful with NULL.

    On MT4, you can use NULL in place of _Symbol only in those calls that the documentation specially says you can. iHigh does, iCustom does, MarketInfo does not, OrderSend does not.

    Don't use NULL (except for pointers where you explicitly check for it.) Use _Symbol and _Period, that is minimalist as possible and more efficient.

  2. On MT4 there is no such thing as 

    ORDER_TYPE_BUY_LIMIT
    Only OP_BUYLIMIT

  3. Check your return codes, and report your errors (including market prices and your variables). Don't look at GLE/LE unless you have an error. Don't just silence the compiler (MT5/MT4+strict), it is trying to help you.

i want my order to expire at the close of the candle

 
So set an expiration (datetime) assuming your broker allows it.
