Oops. My mistake!! Backtesting is adding NO commission when I have setting for "portfolio commission table".

I just ran two backtests. One with IB commissions set in my only Account Manager, .acx, file. The second with $7/trade. The two tests differed only by what you would expect from the differing commissions.

So, it looks like 'portfolio' commission table is now AM one. However, I don't know what happens if you set up more than one AM.

I have emailed support twice regarding this issue but have got no response yet. 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. Thanks!

    In the new version (4.90) of AB, portfolio manager is gone and
    replaced by account manager. 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.
