Cant send single orders - only multiples beyond single lot

[Mindset]

HI
Using some original code from ProfitSniper which I have customised.
I am trying to get this code to work. It works fine with 2 lots or more but gives errors on single lots.
Anyone spot my error?
Edit - mmm... so it appears to be the very first order which will not do single lots. If I do 2 lots, close and then do 1 lot it works

Welll thank you ChatGPT.
The parameter problem was quantity.
I tried moving this to before the Entryorders were even looked at but that made no difference.

I have got round the problem by changing the following lines - replacing Q0 with 1 as it can only be 1 in a single lot order.

else
{
profitTargetOrder = myAccount.CreateOrder(orderUpdateArgs.Order.Instru ment, OrderAction.Buy, OrderType.Limit, OrderEntry.Automated, TimeInForce.Day,1, currentPtPrice, 0, oco, "Profit Target", Core.Globals.MaxDate, null);
submitOrdersArray.Add(profitTargetOrder);
stopLossOrder = myAccount.CreateOrder(orderUpdateArgs.Order.Instru ment, OrderAction.Buy, OrderType.StopMarket, OrderEntry.Automated, TimeInForce.Day, 1, 0, currentSlPrice, oco, "Stop Loss", Core.Globals.MaxDate, null);
submitOrdersArray.Add(stopLossOrder);
}

Hello Mindset,

I'm glad you were able to work out a solution.

Moving forward in the future, if you would like assistance with an error message please provide the full error message.

The issue may have been with the logic assigning the Q0 or Q1 variables a value.
It would be advised to print the variable value with a label and the bar datetime, with TraceOrders enabled to diagnose the issue.
