how do OCO groups and ATM functionality work in IBKR compared to TDA? does IBKR alllow ninja to use some form of tick charts from their data? i know tda does not.
- When submitting orders within an OCO group, the orders must be submitted as a pair and after submission, those orders will no longer be modifiable. To make a change to an OCO grouped order it must be cancelled and resubmitted. ATM functionality which would modify submitted stops and targets on TD Ameritrade accounts are therefore not supported.
- TD Ameritrade supports changing the order type of an active order. This is not a common practice. NinjaTrader does not support this feature.
