Tomasz,
I saw a performance improvement but not the type you were expecting.
I did an 50 step optimization of one variable over 100 symbols. On a
formula complexity scale of 1 to 10 (with 10 being extremely
complex), I'd say mine was maybe a 6.0 (couple hundred lines of
code). I'm running an

Dan,
Thanks.
That's normal. Your formula is complex enough to constitute more than
80% of total execution time and this kind of smaller speed up is to be expected.
Also there is difference between first run (when data are actually read from
files/external source)
and subsequent runs (from cached

Hello,
You can use simple EMA cross over for example
Buy = Cross( Close, MA( C, 50 ) );
Sell = Cross( MA( C, 50 ), Close );
IN MS speek it would be
Cross( Close, Mov( C, 50, S ) )
Cross( Mov( C, 50, S ), Close )
But frankly speaking the comparision you are trying to do makes no sense

I have a problem. My Amibroker is running with real time data streaming via

The answer is Yes - it is possible. You can do what you wanted to do
(i.e. writing files inside WatchLists subdirectory) and it will work OK,
provided that AmiBroker does not have this particular database open
at that time. So FIRST write files and THEN run AmiBroker/open database.

Hello,
No. AmiBroker is smart enough not to require all data to be loaded at the same

It goes through symbols sequentially in first pass, collects signals,
compresses them
so they take minimum required memory, then second phase occurs (actual

This way you can backtest _way_
