Hi All,
Any one have been reading this book ? Based on this book seems that all technical analysis method like chartist and indicator is not far from astrology. :)

This book also divide the trader into naive technical analysis, expert TA and naive quant and TA.
So i think based on that all the strategy seems to be random because of overfitting and data mining bias.
Is that true also with most of strategy in Quantopian ?
How can we differentiate this from the real edge ?
Cheers
