I don't know why a double bottom is stronger than a triple bottom; it just is.
Unfortunately the best evidence I can put my hands on is in Steve Saville's newsletter which is only for paid subscribers.
If I was to guess as to why, given the stock market is primarily based on psychological factors, that coming back twice to support and then leaving it seems strong, but if it comes back yet again, it doesn't feel as strong. "Why did it come back to support yet again after putting in a double bottom already?" But that is only a guess.
And of course any form of technical analysis is only good until it stops working.
BTW, The number of wrong calls made by Sinclair must outnumber his good calls by a factor of 10, at a minimum. I tuned him out years ago for his persistent cries of 'gold price to the moon!". The worst investing gurus are those who make a great call, often by luck, and ride it for years, q.v. Nouriel Roubini.
