Thanks alp.
I visited this link and I may say that Russian viac forum started very interesting thread about self-teaching EAs.
It was stated that some EA was sold many times for $50 - $150 and are selling now. It was posted the code of this EA as well.
It was stated that this EA is self-teaching: it remembers the price movement model and implements it during the trading.
It is necessary to do backtest this EA 2 or 3 times.
First time backtesting: M1 timeframe for 2 or 3 days.
Second and 3rd: backtesting on M1 timeframe during the 1-2 years.
After that this EA will create some files in terminal_dir\tester\files. Re-place those files to terminal_dir\experts\files because EA will use it during the real trading.
Somebody who is doing the forward test of this EA posted the login and password to his Metatrader so everybody may see the trades.
I can not say anything concerning this EA: I do not think that it is grail. But this subject about self-teaching EAs is very interesting.
I think that our programmers should look at the code posted on this link and explain to us about this self-teaching. No need for programmers to understand the Russian language to visit the link above. Everything is understandable.
I think that some pieces of the code responsable for this self-teaching may be used in our EAs.
