I'm newbie in mql4 . Suppose I buy a currency pair in price of 1000. TP is 1500 and SL is 800. What I want is: When prices goes up to 1300, I change SL to 1200 . In other words, when price reaches to 1300, it closes when price goes down to 1200 or goes up to 1500 . How can I code this? My code for now looks like this: int tiketbuy=OrderSend(Symbol(),OP_BUY, Lot,Ask, Slippage, Ask-Distance,Ask+(2.5*Distance),NULL,1111,0);
