Do you would know someone to say me if a stop loss negative it is equivalent to a positive profit?
extern int SL_Down_SELL=-3; //negative value
extern int TP_Down_SELL=40;
Thanx in advance
You've made a fundamental mistake - you are trying to enter a relative number of pips as the stoploss and takeprofit parameters in the trading function call.
The parameters must contain the calculated PRICE at which you wish to close the order.
