In an endevour to save transaction costs, I am rewriting the entrance and exit mechanism of my NinjaTrader strategy. The strategy uses a profit target and a runner for each trade signal. Originally, I was using two orders: orderA with a target, and orderB with no target. But, if I place one prder, and use a limit order to exit 1/2 of the position, I can save on entrance transaction costs.

Over at the NinjaTrader forum, support says this is not possible: link.

Are they correct? Their answer feels incorrect, is not congruent with the rest of NT syntax, and contradicts NT documentation. Unless I am mistaken, I think that I have done this very thing. [Though, I haven't had time to fully test it.]

Am I mistaken, or is NT support mistaken?

Is it time to take the plunge and use NJAMC's LOM?

Kinda surprised at no replies yet.

Anyway. According to a new reply from Ray, this is a known bug. Scaling out using a managed approach works in backtest, but fails in real-time: reference here. Ray says this will be fixed in NT8.

Perhaps this was known on the NT8 threads here at Big Mike's. It was not to me.

FYI.

Well, what are you trading ?

Futures are charged by contract and not by order so you would not save anything.

Math. A gateway drug to reality.

Hello,

My understanding is that the NJAMC's LOM does not work with backtesting but does work with the Market Replay data. And maybe the GOMI Recorder data??
