I don't think this is right,

You can write it like this, Print("i= ",I," order number = ",orderticket ());

//You can use this to close your position.

if(order type()= = OP _ BUY)order close(order ticket()，OrderLots()，Bid，3，Blue)；

if(order type()= = OP _ SELL)order close(order ticket()，OrderLots()，Ask，3，Red)；
