The FSB POro experts work smoothly after a restart or reload. The expert internally is implemented more or less as FSB Pro. It has several major parts:
- data manager that collects the necessary historical data for the indicators and the account statistics for the position calculation.
- strategy calculator - it calculates the builtin indicators
- trading engine - it uses the current data, teh positions status and the strategy to calculate if new orders are necessary.
- trading execution module - it sends the actual orders and monitors the execution.

All operations run at every tick. It means that the strategy becomes completely aware of what is the current account status and trade accordingly. The only exception (as far as I remember) is Martingale. It may happen to forget the count of the consecutive wins or losses.

I suppose that the Portfolio Maker doesn't break the proper strategies work.
