If possible, could the person who is finalizing this code please post
it?
I would like to run something similar... and this might just be a great
start!
thanks,

Yes and thanks. I just figured this out via trial and error just before reading you reply. thanks again.

Same as you did for loading the formula itself.
AA.LoadSettings("c:\\Amibroker\\Settings\\SettingsBasic.ABS");
I would load the settings first, then make whatever additional calls to configure before running the exploration/backtest/whatever.

Mike - I saved the settings file, but do not know how to load in _javascript_. The file is c:\Amibroker\Settings\SettingsBasic.ABS
AA.Loadsettings something?

1. I have not tried running your code. But a few observations:
a) Before ever running the script, you might want to consider saving your settings out to file such that you may load them in from your JScript to ensure a consistent environment. This is also the only way that I've found to set your optimization target by the way.
b) No need to wrap Explore call in braces (i.e. don't need {}). Same with block for exporting.
c) Don't think that you need to save your database or restore all after the exploration.
2. AB.ActiveDocument.Name = "RUT-I";
3. Not sure what you're asking here. Do you want to generate 10 .csv files, or read in from 10 .csv files? Assuming that you want to generate files, you can do the preparations/explore/export in a loop.

I created the following _javascript_ to do an exploration on an afl and then export the exploration to a file. I have a few questions.
1. From a structure perspective, is there anything that I should include or exclude as I try to pick up _javascript_.
2. I can not figure out how to load a reference symbol like "RUT-I" with is the R2000 so that AmiBroker knows the valid market days.
3. How to change the following if I want to loop through 10 csv files rather than just the watchlist 9 used in the following? That is, do this 10 times automatically but on csv files named In1.csv to In10.csv, if you will.
By the way, I am going through a learning process to expand my knowledge on what to do in afl, what to do in _javascript_ and what to do in AutoIt. This is part of that process.
