Access Instrument Commission from Ninjascript NT8

[NinjaTrader_Jesse]

Hello timcjpfx,

Unfortunately I wouldn't be able to say why that may be null, that is not a documented property on the Account object so it may not be intended to be used in NinjaScript but only in specific internal uses.

timcjpfx, What happens is that the account associated with the strategy does not have a commission defined. Edit the account you are using to run the strategy, and assign a commission to it, and you will see that your code works that way. To avoid this problem, put a conditional in your code where you ask if the variable is not null so that the value assignment can proceed; otherwise, you can pass the value zero to the variable.

This answer is a bit late, but I'm just getting into the world of NinjaScript. I hope you were able to solve it in due time.

Hello timcjpfx,

Do you have a commission template applied to the sim101 account? You can right click -> edit account from the accounts tab in the control center to check that. If this is in a backtest make sure you have checked the use commission box as well.
