There is no theoretical limit in the number of accounts, but as you approach and exceed 20 total accounts, NinjaTrader could begin to struggle in certain situations.

Let’s consider using Duplicate Account Actions in ‘Orders’ mode. For example, if you are placing a 3 contract trade entry with 3 Targets configured in the ATM Strategy, this is a total of 6 exit orders, multiplied by 20 accounts, you have 120 orders being placed simultaneously. This can quickly get out of hand additional trade entries – it becomes 240 pending orders, and then 360 pending orders.

You will want to consider using Duplicate Account Actions in ‘Executions’ mode if managing situations where the total number of pending orders at one time will exceed 200 orders – this includes all entry orders, Stop Loss orders, and Target orders.

No one is more committed to maximizing the potential of NinjaTrader to build the best performing trade copier to place and change orders as quickly as possible.
