onExecution execution.Order is null

[zark.be]

Hello

still trying to migrate the same 6.5 strat to 7

I've noticed IExecution.Order is sometimes null in the onExecution() method .

Actually it happens only with a Close Position IExecution.

This wasn't the case in 6.5, this is probably new normal behavior in 7
(as now i receive a separate Close Position order, then the Filled order).

But it is not mentionned in new Documentation.
also, what would be the recommended check ?
right now i've added if(execution.Order !=null) which seems the best check possible since checking on the execution.Name string is just "meh"



If needed, script to reproduce issue :

 protected override void OnBarUpdate()
        {
			
			if(Position.MarketPosition == MarketPosition.Flat)
				EnterLong(1,"Enter");
			
				if(ToTime(Time[0]) > 161400)
				{
				EnterShortLimit(Close[1]+5);
				
				}
			
		
        }
		
		protected override void OnExecution(IExecution execution)
		{
			
			if(execution.Order !=null)
		log(execution.Order.OrderState.ToString());
			else
				log("order is null");
		
		}

Hi zark.be, thanks for the report, I'll look into shortly.

zark.be, this is expected for NT7, so a check for null is needed as you correctly done - we'll add to the docs shortly.

I thought so, and it's a nice addition, i'll have to make sure to update my strats to this new behavior as i wanted something like this in 6.5


Thank you.
