Limit to take off 1 contract on chart trader

[NinjaCustomer]

is it safe to put a limit to take off 1 contract when it's hit ? I mean will chart trader adjust the initial trade (e.g. 3 contracts) both TP and SL values from 3 down to 2.

specifically I'm using Rithmic if that matters

Hello NinjaCustomer,

With your 'Active ATM Strategy' selected, set your order quantity to the desired value, then submit an order on the opposite side of the market.

When this order is executed, your position will be reduced and stops/targets will be adjusted to account for this change in position size.

I have also provided a link to video that is publicly available below that goes over Scaling In and Out of an Active ATM Strategy.
