Ability to generate strategies that open more than one trade at a time

Looks like SQ4 one opens one trade at a time (there are no overlapping open trades).

Please allow the ability to have open multiple positions. 

At it's simplest I would like to see a couple of suggested limits:

1. Max open positions
   
   SQ4 will open new positions up to a limit (E.g. 10 - configurable).  Beyond this new trades won't be opened until the open trade count falls.
   
   
2. Max open drawdown
   
   SQ4 will open new positions, up until the total open trade drawdown exceeeds a limit (E.g. 10%  of balance - configurable).  Beyond this new trades won't be opened until the open drawdown % falls.
