That's a very difficult question, I don't know. I did spend thousands and a lot of time, but then again I am not a genius. I wasted a few Gs in retrospect. And I am not sure I already have everything figured it out.Quote from Kicking:
I read somewhere , I think it was here, that Gann's work as compiled by other people after his death was incomplete and the key to his trading secrets may have disappeared with him. What I read on this thread seems to corroborate that. If this is the case, only part of the puzzle is available; how difficult is it to study what is left in terms of time and money and make it usable ? In his book, The Daytrader, Borsellino mentions he used Gann charts that he had bought for a huge amount of money, do you have to spend thousands too to learn about Gann?
Trading is expensive, if you're not prepared to spend thousands even if you won't use Gann then don't trade.
