I love the idea of a discussion about rules based vs discretionary trading. Thank you for suggesting it.
For the past 5 years I have been running a rules based automatic trading system. However before that I used to be a discretionary day trader on a trading floor. These trades were based upon whatever the news of the day was.
I personally believe that if you practice, and become good at it, discretionary trading should be more profitable than any rules only computer system just as a expert chess player with the help of a computer program should be able to beat that same computer program alone.
The problem is that it takes a special skill that must be learned, and then tailored to the traders personality, and a source of good real time information to act upon. Most people do not have the time, and patience required to build a good rules only system, let alone a discretionary one that also takes advantage of a rules system.
As for the fact this forum basically is about rules based systems only, that is the nature of a computer backtesting program such as Amibroker.

Hello,
Not wanting to hijack this thread but whenever I ask
about some itemized list of what is exactly "weak" in AB charting,
I don't receive any meaningful reply. I would really want to know
some objective list instead of statements I heard on ET that
"charts are ugly" which for me unfortunatelly means nothing,
considering the hunderds of ways charts can be customized
according to user taste in AB.
Best regards,
Tomasz Janeczko
