Deleting specific orders

[Forex Trader]

Greeting all,
The below code is meant to delete, for a specific symbol, a pending buystop order if the bid is less than open[0] or a sellstop order if the ask is greater than open[0]
It does not work :(

Anybody have an idea what is wrong .... Thanks

total=OrdersTotal();
for(cnt=0;cnt<total;cnt++)
{
OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES);
if(OrderType()<=OP_SELLSTOP &&
OrderSymbol()==Symbol())
{
if(OrderType()==OP_BUYSTOP)
{

if( Bid <= Open[0] )
OrderDelete( OrderTicket() );
return(0);
}

if(OrderType()==OP_SELLSTOP)

if( Ask >= Open[0] )
{
OrderDelete( OrderTicket() );
return(0);
}
}
