为什么不能实现移动止损

[q4226674]

问一下这个 EA为什么不能实现移动止损
选择启用警报 然后在赢利3点之后就直接跳出修改止损的对话框 而不是自己修改移动止损
该如何改正？
extern double TakeProfit = 100;
extern double TrailingStop = 3;

int start()
{
int cnt, ticket, total;
total=OrdersTotal();
//if(total<1)
// {
// return(0);
// }
for(cnt=0;cnt<total;cnt++)
{
OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES);
if(OrderType()<=OP_SELL && OrderSymbol()==Symbol())
{
if(OrderType()==OP_BUY)
{
if(TrailingStop>0)
{
if(Bid-OrderOpenPrice()>Point*TrailingStop)
{
if(OrderStopLoss()<Bid-Point*TrailingStop)
{
OrderModify(OrderTicket(),OrderOpenPrice(),Bid-Point*TrailingStop,OrderTakeProfit(),0,Green);
//return(0);
}
}
}
}
else
{
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);
}
}
}
}
}
}
//return(0);
}
