Quote from retaildaytrader:
I have never seen a successful trader use technical analysis. Maybe my experience is too limited, therefore, I challenge you to name ONE trader, money manager, etc. who uses technical analysis and is profitable. Name just ONE.
Read Market Wizards and see for yourself.
From those books you will learn that there is no one approach to trading or investing, even though there are many themes that are repeated across the different styles presented.
It is however no doubt that there are plenty of traders in that book, fund managers included, that use technical analysis to form trade decisions.
From the top of my head I remember Marty Schwartz saying how he traded poorly from fundamental analysis for ten years, but after he started using technical analysis he became successful.
As for why wedges and triangles work, it can only be because they may help the trader visualize how the price action is playing out. It`s not because it is a wedge or a triangle

If a market is trading in a range, eventually it has to break out of that range, yes?
If price breaks out of a triangle, it simply breaks out of a range. It`s not because it is a triangle

That`s my take on it.
