Slawa How to Close trade and Open new one at same Bar???
Example:
Short trade is open already or TotalTrades=1 (OPEN SELL).At the begining of new bar there is signal for long trade.EA first close short trade and after that open long trade but at same BAR(for example M15).
Please help???
Jeff
 
the simple example
if (BuySignal)
  {
  if (OrdersTotal()>0)
    {
    for(int i=OrdersTotal()-1,i>=0,i--)
       }
       if (OrderSelect(i,SelectByPos))
          {
          if (OrderType()==OP_SELL)
             {
             OrderClose(OrderTicket(),OrderLots()...)
             }
          }
       {
    }
    OrderSend(Symbol(),OP_BY,...) 
  }

Thank you.But there is no trade.Try it.
int start()
{
double BuySignal=0;
if (Close[2]>Close[1])
{
if (OrdersTotal()>0)
{
for(int i=OrdersTotal()-1;i>=0;i--)
{
if (OrderSelect(i,SELECT_BY_POS))
{
if (OrderType()==OP_SELL)
{
OrderClose(OrderTicket(),OrderLots(),Bid,3,White);
}
}
}
{
OrderSend(Symbol(),OP_BUY,1,Ask,3,0,0,"",0,0,Blue);
}
}
}
//----

//----
return(0);
}

Also can you insert code for short position(SellSignal).Thank you.
