Greetings --
I do not offer a solution, rather a question. What is in those files, and how will they be used? Will they be used as components of trading systems that will someday be traded?
If the data in the ASCII files is available from a vendor for which there is already an AmiBroker data plug-in, then using that vendor's data rather than the ASCII gives several advantages:
1. The research data and the trading data come from the same source. Consistency is very important in trading system design. Maybe more important than accuracy.
2. You let the vendor be in the data management business, while you spend your time developing trading systems.
3. You bypass the task of importing the ASCII files for the research project.
4. Think ahead to how the data will be gathered and imported into AmiBroker while trading. If you import the ASCII files for research, where will the data come from for trading? Will you be able to gather the data, edit it, import it, and still have a timely signal?
My use of ASCII files is for one-time projects. If the data turns out to be useful, I look for a data vendor who can provide it in the form I need it and on the time schedule I need it.
Thanks,
Howard

I don't have an answer for you, but I do have a couple of questions,
because I too have over a thousand ascii files that I would like to
import into AB.
Have you completely automated the task, using not only the suggested
jscript but also set up a list of all the equities to load, so that you
can just let AB take it from there?
Or is much the time your 'hands on' time, for example manually typing
in symbols or clicking mouse buttons for every symbol?
Thank you for bring up this issue. I sure hope others with applicable
experience chime in.

I try to import thounds of ascii files to Amibroker by JScript.
(http://www.amibroker.com/docs/ab302.html)
It works but very slow.
Is there any quicker way to batch import ascii files ?
Or can I write data directly to the Amibroker's data file ? (what's the
data format ?)
Thanks !!
