I have a simple ATM strategy that plots a stop and a target.

If I try to add contracts I get an error saying I can't submit an exit order to a strategy until any of its entry orders has been filled?

Hi Mindset, what is your ATM Strategy selection mode setting?

all ticked

To scale into a position while updating the original Stop / Target orders with the new quantity, you will need to use the ATMStrategy Selection mode setting 'Select Active ATM Strategy on submission'. Please see this link for more info - http://www.ninjatrader-support.com/HelpGuideV6/StrategyMode.html

You can right click in your SuperDOM or ChartTrader panel and bring up the 'Properties' to change this under 'General'.

I have an option selctactiveatmstrategyonordersubmission. (already selected)
I have one other option with the word keep in front of it

[NinjaTrader_Bertrand]

Your already selected option will amend existing Stop and Target orders when you scale in.

The 'Keep selected ATM Strategy...' will create a new set of Stop and Target orders when you scale in.

Which type of orders do you place on which product? Thanks!

Thanks - the keep option seems to do the job. I hadn't realised the other tried to amend the existing order. trading 101.
