Moving a stop

[GKonheiser]

In a strategy I set an initial stop with the line of code below:

stopLongEntryPP = ExitLongStop(0, true, execution.Order.Filled, pp - stop * TickSize, "Stop of Long PP", "Long Entry PP");

If I want to change that on certain price conditions I take it I do this in OnBarUpdate? But when I try and use the execution.Order.Filled in OnBarUpdate I get an error. Am I only able to use execution.Order.Filled in OnExecution? If so what is the best way to reference the current position size?

Thanks

Hi,

The parameter you're accessing is read-only from the OnExecution method.

If you'd like to get the current position size you can call Position.Quantity in OnBarUpdate:

Print("Position.Quantity: " + Position.Quantity);]

You could also just pass the execution.Order.Filled price from the Execution

        protected override void OnBarUpdate()
        {
			// pulled from OnExecution
			Print("executionQty: " + executionQty);

         }
			
         protected override void OnExecution(IExecution execution)
        {
			executionQty = execution.Order.Filled;
	}

That's great thanks. Is there a way of checking which iorder is the current execution if it has been reset to null?

Sure, there are a lot of properties you can read from the objects

		protected override void OnExecution(IExecution execution)
		{
			if(execution.Name == "myOrder")
			{
				Print("myOrder was executed!");
				executionPrice = execution.Order.Filled;
			}
			
		}

Examples of checking for null can be found from the following link:
