int start()
{
int ticket,expiration;
double point;
//----
point=MarketInfo(Symbol(),MODE_POINT);
expiration=CurTime()+PERIOD_D1*60;
//----
while(true)
{
ticket=OrderSend(Symbol(),OP_SELLSTOP,1.0,Bid-100*point,0,0,0,"some comment",16384,expiration,Green);
if(ticket<=0) Print("Error = ",GetLastError());
