Greetings all --
I am writing a book -- Introduction to AmiBroker -- that will help some people. I expect it to be available in early 2008. It will fill in the area between zero and Quantitative Trading Systems, the book that was published earlier this year.
But no matter how good the AmiBroker documentation is (and I think it is already excellent), or how good the AFL Wizard is (it is also excellent), or how many books are read, creating profitable trading systems still requires serious effort and understanding -- coming up with ideas, translating them into AmiBroker code, testing the code, debugging the code, verifying that the code performs as intended, selecting issues to trade, backtesting the trading system, deciding on a goodness metric (and adding it as a custom metric to the performance statistics if necessary), performing out-of-sample tests, and validating the trading system. Then trading it.
No matter how clever Tomasz is with the AFL Wizard, it is the responsibility of the trader him or herself to understand how the trading system works. The trading system Is computer code, and the open, high, low, close, volume series it processes Is data. I would be naive if I thought I could understand the trading system well enough to trust my money to it without understanding the computer code, its interaction with the data, and details of generation of the trading signals.
The low-hanging fruit of computer-based trading systems has already been picked. Simple systems no longer work. Everyone hoping to develop a profitable mechanical trading system Must understand the language in which it is written. It makes no difference whether the platform is AmiBroker, TradeStation, MetaStock, Wealth Lab, or whatever else. Not understanding is placing trust in a black box.
AmiBroker is outstanding! I have experience with most trading system platforms, am fluent in many of them, and have written one myself. AmiBroker is outstanding -- it is clearly the best platform available to us common folks today, and Tomasz is pushing it farther forward with every new release.
I participate in a regular exercise class. About once a week, one of the class members complains about how hard we are being asked to work. The instructor turns, asks "Who's whining? No whining!" We are all there by choice.
We are all working with AmiBroker by choice.
Let's get back to a more profitable use of the discussion group.
Thanks for listening,
Howard

There was a discussion about this on AB-TS (?) a
couple of months ago. Bottom line, most can probably shorten the learning
curve by first going through one of the DIY "how to do it" books on programming
in C, C++, etc. In a relatively few pages, the mysteries of loops,
if-then-else, etc. will become clear to most readers, allowing them to
concentrate on AFL code and coding trading/charting
schemes.
