Given That

日期:2015/07/10

Given that a swing has covered a territory of x, and a turning point has been reached, what is the ideal point vis a vis return and risk to exit on the way back. And how should the turning point be defined, hopefully with less retrospection and naivete than the professor's with the 200 year trend following system. By the way, how did their trend following work when big money could actually follow it? I believe a run of of length 8 x when x is an unbroken 5 move might have a very positive expectation after a swing in the opposite direction of 2.
