Hi
I have a problem with ulong in MT5. Can you help me.
If I use ulong i get errors. If I replace ulong with long there are no errors but I get warnings. I will post the respective code below if you can help me with it please.

int CountOpenPositions(){

int counter = 0;
int total = PositionsTotal();
for (int i=total-1; i>=0; i--){
long ticket = PositionGetTicket(i);
if(ticket<=0){Print("Failed to get position ticket"); return -1;}
if(PositionSelectByTicket(ticket)){Print("Failed to select position by ticket"); return -1;}
long magicnumber;
if(!PositionGetInteger(POSITION_MAGIC,magicnumber)){Print("Failed to get positionmagicnumber"); return -1;}
if(InpMagicNumber==magicnumber){counter++;}
}
return counter;
}

bool ClosePositions(){

int total = PositionsTotal();
for (int i=total-1; i>=0; i--){
if(total!=PositionsTotal()){total=PositionsTotal(); i=total; continue;}
long ticket = PositionGetTicket(i); // select position
if(ticket<=0){Print("Failed to get position ticket"); return false;}
if(!PositionSelectByTicket(ticket)){Print("Failed to select position by ticket"); return false;}
long magicnumber;
if(!PositionGetInteger(POSITION_MAGIC,magicnumber)){Print("Failed to get position magicnumber"); return false;}
if(magicnumber == InpMagicNumber){
trade.PositionClose(ticket);
if(trade.ResultRetcode()!=TRADE_RETCODE_DONE){
Print("Failed to close position. Result: "+(string)trade.ResultRetcode()+":"+trade.ResultRetcodeDescription());
return false;
}
}
}
Thanks
