Quote from SunTrader:
Boris Schlossberg: "Price patterns are simply the reflection of human reactions of fear and greed to ever-changing news flow. They are not some randomly generated numbers from an Excel spreadsheet, even though they make look very similar. This is the critical flaw of pure randomness theorists - just because random functions can often mimic price patterns does not mean that price patterns themselves are random."
In fact you can apply technical analysis to other "real" data such as auto sales, employment reports and populations counts with suitable results,
And Tomas de Torquemada - head of Spanish Inquisition in 1483 said " Earth must be flat otherwise the rivers would flow out of it! Just because we cannot see the end of Earth it does not mean that it is not flat!"
