Quote from j2ee:
I read some reviews/comments of the book and people say there aren't any real backtests in the book to show astrology/Gann way works, well it is still a very interesting topic but I doubt any human in the world can really have a backtested profitable trading system with astrology/Gann way.
You have read more about this than I've done, so I will not say against you. My assumption was more related in the direction of the "random" trading.
If an index return 6% each year, then a 100% random trading system would be expected to give the same return when you run a large number of backtests. I guess that would be the explanation to why someone could say that astrology will return profit. Unless one believes that stars and planets have a real effect on the market....
But I think you are able to create better trading systems than "random". A friend of mine has a really good webiste where you might find some inspiration, he is a very successful trader.
