If you are talking about this tool index so I dod not try (to use graphical possibility in MT4 to open, modify the order and so on - to trade, automatic modification the orders and so on).

The author is well-known person and we are using his free trading simulator sometimes to backtest indicators and trading systems (i will try to do it now for re-painting/not re-painting issue for this thread Repainting indicators )

His version #1 is free to use and download.
Version #2 is under development (it is written on his website).
