Mark, I am sorry that you did not get response. Will ask Marcin why. As to your question: the functionality to use portfolio account commission table in the backtester was not removed per se, what is hidden is ability to access "old portfolio" commission table. You can access it however using previous version (4.89 for example). In the upcoming versions backtester will gain multi-tiered commission table as it is already present in the account manager.

Does anyone know whether this feature (using portfolio commission table for backtesting) has been removed from the new version 4.90 because it is not compatible with the new account manager? I just want to find a way to get it work because IB has raised their commission maximum from 0.2% to 0.5% of trade value, I need to re-test my systems.

When I use commission mode as "Using portfolio commission table" in backtesting, how does AB choose an account to use for commission calculation? It seems that this option has no effect (commission is always 0) Thanks, - Mark H.
