[s loo]

Can you help me correct my coding , in which I'd like to trail both TP and SL, may be I am too optimistic but it seems do not working. please help to correct it : it is a function looks like this following:

////////////////////// trailing profit BOOL function /////////
void TrailingProfit()
{
if profit<=100 useLossToClose=false;
else useLossToClose=true;

if profit>profitToClose
lossToClose=profitToClose;
profitToClose=profitToClose+50;

}

and I put it in the EA like :

int start()
{
TrailingProfit();

....

}

Thank you.
