Yes, it's incorrect. Your trend channel is drawn incorrectly, so whatever mean there might be is useless for trading.
A reversion to a mean isn't going to do you any good unless you're looking at the same price movements -- and their means -- as professionals, such as the channel I drew in the first post (this should not imply that professionals necessarily look at channels; the channels are merely "footprints"). Once price reversed off that mean, then it's back to the balance between supply and demand.
This morning, for example, supply had the upper hand, but soon after the open, demand took over and rose 35pts. Several people saw this trade but didn't take it out of fear. But that's a problem that's outside this particular approach. One can't profit from a trade he doesn't take.
