Help! - How to make trailing stop not take losses when negative profit?

I am back testing using MB trading demo. Th standard trailing stop code will not take into consideration of the commission and order swap.
Anyone had tried successful to have the trailing stop not take losses with negative profit?

typical trailing stop code:

void ShortTrailingStop()
{
int scnt;
int stotal = OrdersTotal();

for(scnt=stotal-1; scnt >= 0; scnt--)
{
OrderSelect(scnt, SELECT_BY_POS, MODE_TRADES);
if(OrderType()<=OP_SELL && OrderSymbol()==Symbol())
{
if(OrderType()==OP_SELL) // short position is opened
{
if(TrailingStop>0)
{
if((OrderOpenPrice()-Ask)>(Point*TrailingStop))
{
if((OrderStopLoss()>(Ask+(Point*TrailingStop))) || (OrderStopLoss()==0))
{
OrderModify(OrderTicket(),OrderOpenPrice(),Ask+(Point*TrailingStop),OrderTakeProfit(),0,Red);
return(0);
}
}
}
}
}
}
}

Easy. Just have the trailing code add up the profit=profit+OrderProfit() and refuse to cashout unless the profit>0. - You'll have to close the orders by program code instead of using a in-order stoploss though.

Thanks for your reply,

Then it does not trail, it will just take profit when there is profit
require OrderModify() function for trailing,
but the "double stoploss" Parameter is the cause of the problem. It will not work with commissioned broker.

Is there a way to work around this?

Well Im not too sure if it would change the end result of the code at the moment, but I think I have seen this little bit mentioned in some other thread recently.

if(OrderType()<=OP_SELL
will always be true, something to do with OrderType() is not a number.
I think you get away with it cause of your next if() ie
if(OrderType()==OP_SELL)
See in this 1 you are checking if it is equal to OP_SELL, which is the correct usage. Checking if less than OP_SELL isnt the right usage (gramar?)

I think there is a swap value stored for the order, but not sure about commission.

Thanks for you reply.

That is not the problem, I've just change it to ==

FYI
that was to check if it is OP_SELL or OP_BUY which will return 1 and 0.
<= 1 or 0.

Not the reason for the Tailing Stop Loss to sell at loss.

The routine gets a little involved. You have to compute the highest pip profit achieved since the order was opened. Subtract your trail factor. If trail would be activated then also check if order is in profit. If so allow order to be closed. You'll have to use iBarShift on M1 and iHighest or iLowest to calculate the highest or lowest price achieved since order creation. Start with the OrderOpenTime() and move forward to current time and find the Highest/Lowest price (depending on if its a BUY or SELL). Also keep tally of OrderProfit() - If its in the profit close the order with OrderClose().
