If Technical Analysis is working, why is not possible to program a bot to do it automatically?
The bot will be much faster than any human, will not make any numeric error, will not fail due emotions, will work 24/7 and also could analyse thousands of markets at the same time. And will be easy to develop! the rules for Technical Analysis are very simple.
EDIT: I am a developer, I know there are bots out there of course, I coded one myself too, and I did a lot of backtesting. And none of these bots works, that's my question, why the bots are not working if they use technical analysis. Why a human can make profit using technical analysis and a bot can not? If they are much more accurate than us making technical analysis...
LAST EDIT: I asked this in the wrong way, my question was about the public and well known strategies used in TA, like RSI overbought/sell, MACD, BB, etc. Because I'm new in trading and I can see a lot of people drawing this Fibonacci retracements, weird things like harmonic patterns, and I can't understand why people waste time drawing those things, if they work they could just create a software to detect them and buy/sell automatically. And if they don't work why those things are so famous, are all them scam? are these techniques just a tramp for beginners like me?
