Yep, We need a simple way of Adding more pairs or Removing pairs from a project without restarting or beginning a new project.This is to prevent having to run new projects & loosing the essential Loss/Profit pips displayed on the chart / Account History data.
Simply put, adding a pair or 2 as the project progresses & removing pairs as the project progresses thankfully with your new Risk % feature on every trade which will sustain the account balance.
It will help many to keep to process without having to jump from project to project which is more like jumping from strategy to strategy with no coherent process. Hope the "pair portfolio" won't freeze up Forex Tester, but I believe Forex Tester was created to outmatch MT4/5 which handles multiple pairs very well on Indicator Data History Cleanup
