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.
  Best regards,
Tomasz

    table
    
    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,
