Expert tab Error # 1

[Wackena]

I'm getting repeated error message in my FDXX Demo Terminal window expert tab.

"Expert Name".USDJPY,M15:OrderModify-Error # 1

mql error code 1 is "No error returned, but the result is unknown."

Could someone advise what could cause this type error?

Thanks,

That usually means that OrderModify() has nothing to do with the parameters it's called with.
I.e all the levels are the same the modified order has already.

Hint: check if the modification parameters are different from existing ones before the call.

Not sure, but could this be the problem? OrderModify() is like OrderSend() and must have the spread difference between current Ask/Bid and new Stoploss level.

If OrderProfit() is very low, could OrderOpenPrice() be too close to current Ask/Bid, then the spread may come into play when trying to set new Stoploss level. Result then is OrderModify() - Error # 1 in the Experts tab in Terminal pane.

Again, not sure, just a thought.

if(OrderProfit()>0) 
{
OrderModify(OrderTicket(),OrderOpenPrice(),OrderOpenPrice(),OrderTakeProfit(),0,GreenYellow);
}

This is definitely the problem as OrderModify() is called with the same parameters whenever OrderProfit is positive in your code.
