Scaling in with ATM-is this possible?

[JImJinNJ]

can scaling in be done with ATM capability in NT7?
if not, how can this be done? must it be coded into a system?
also, if someone can direct me to the appropriate part of NT documentation for more info.
Thank you very much for any assistance.

The below assumes you're using the SuperDOM, but the concept is the same for Chart Trader.

When you have an active strategy selected in the strategy control list, orders submitted scale into or out of the strategy. Once filled or partially filled, existing stop loss and profit target orders are modified to reflect the new position strategy size. You can preset a default scale in or out quantity via the "Scale quantity" property accessible via the SuperDOM properties window. As an example, your initial strategy may call for opening a position of four contracts but you want subsequent scale orders to be only one contract. If the SuperDOM "Scale quantity" property is set to a value of one, when an active strategy is selected in the strategy control list, the SuperDOM "Order qty" field will be set to a value of one automatically.

Please see the "How to scale in or out of an active ATM strategy" section of the link below for more information and a video:
