'If Technical Analysis works then tell me where the market is going to be tomorrow'.
An old gold miner saying is, 'The easiest place to find gold is a place gold has been known to be'.
With good trade management techniques money can be made in markets on random coin tosses. To vastly improve on random walk TA doesn't need to predict market direction only to identify areas where volatility is likely to increase.
For example if everyone is praying while waiting for a market to break out of one of the various triangle patterns and you simultaneously place a buy above and a short sale below the triangle with a stop loss at the breakout point. If the trade succeeds you cancel the opposing order. If the trade fails it is closed out with a minimal, predetermined loss and the trade in the correct direction is triggered.
Lather, rinse, and repeat a few times and you are a successful trader booking profits while others are busy trying to find the news story that makes them feel better by making someone else responsible for their losses.
You're the only one who can choose your belief system so be careful which you choose.
