do you have a system you've tested and trying to trade? If not then maybe
you need to concentrate on that before you spend a lot of time on this part.
If you do then I can probably give you some guidance/pointers/whatever.

Subject: Re: [amibroker] creating a basket order file
hi,
I am still working on the making of a file that contains order lines for
Interactive Brokers "basket" trading. I have been playing with a test system
in AFL (see result below). But the problem still is that I want to know
exactly what to sell and how many. Also I have problems starting a "fresh"
file for each new backtest. But I am afraid that with only using AFL it is
not possible to make this file.
I guess the solution is to use scripting and create data objects and derive
the info from them. In the archives there is some stuff I found and maybe if
I plough real deep something will surface ..... but could somebody direct me
how to best learn to use this scripting. There is some in the manual but if
there is some other place to learn this please let me know (especially about
which objects and methods that can be used).
