Yes, that is what I would like to be able to do..... it is the 
Discretionary Traders backtester.

If I used that term I used it rather loosely ... if Alan used it I 
know what he meant..... fair enough, reserve the term for Walk
Forward as we know it now ... yes, they are different processes..... 
let's use something else, for what Alan wants, to avoid confusion.

Yes, I am only talking about a live simulation with the 
trades 'recorded' for later analysis AND/OR live metrics/money 
management (part A would be a good start) .... I still like the idea 
of being able to store the trades in static arrays that can be 
accessed via AFL.... don't know if that would fit in there or not.
