TJ... I appreciate the fact that Amibroker is a 'work in progress',
and I know that as time passes it will only get better and better.
Since I trade everyday using BUY LIMIT/STOP/STOP LIMIT / ETC orders, I
have a strong need to backtest with these standard order entry methods
without having to go into AFL coding contortions to try to see if a
stradegy works.
I know now that you are aware of the need to implement these features.
Nuff said.
