Great post and so true...Academics are not traders, traders are traders. However academics are generally smart people who are adept at devising quasi-empirical bullshit to razzle dazzle the great unwashed while bolstering tenure as well as stature among the theorists. If there were no edges, algo's could not make money and they are written by humans who understand the nature of price development. Those who put in the study and work can ultimately understand such but few do, therefore "markets are random", "PA/TA doesn't work (whatever the fuck means)", "only the institutions can make money, the markets are rigged" etc etc. Those who have done the work understand the probabilities of price direction given defined technical conditions as well as the risk and reward scenarios for a given trade. BTW, the worst way to learn to trade is to engage in these endless and mindless discussions.
