Help with trailing stop function.

I have been running this EA on demo account but I notice that the trail feature doesn't work all the time causing it have more losses. I pasted the part of the code here cuz I have very little experience with programming: could someone please look at it this part of the code and see if there might be any possible problems. Any help or feedback will be appreciated. Thanks in advance

void TrailStop() {
bool bres;
double StopLoss;
if ( TrailingStop > 2 ) {
for (int i = 0; i < OrdersTotal(); i++) {
if ( OrderSelect (i, SELECT_BY_POS) == false ) continue;
if ( OrderSymbol() != Symbol() || OrderMagicNumber() != expertId ) continue;
if ( OrderType() == OP_BUY ) {
if ( Ask < OrderOpenPrice()+TrailingStop*Point ) continue;
StopLoss = Ask-TrailingStop*Point;
if ( StopLoss > OrderStopLoss() ) {
bres=OrderModify (OrderTicket(), OrderOpenPrice(), StopLoss, OrderTakeProfit(), 0, White);
if (!bres) Print("Error Modifying BUY order : ",ErrorDescription(GetLastError()));
}
}

if ( OrderType() == OP_SELL ) {
if ( Bid > OrderOpenPrice()-TrailingStop*Point ) continue;
StopLoss = Bid+TrailingStop*Point;
if ( StopLoss < OrderStopLoss() ) {
bres=OrderModify (OrderTicket(), OrderOpenPrice(), StopLoss, OrderTakeProfit(), 0, Gold);
if (!bres) Print("Error Modifying SELL order : ",ErrorDescription(GetLastError()));
}
}
}
}
return;
}
