exactly. I highly respect this person, but it sounded like they just went through and adjusted their settings till the found the one that touched the bottom of the reversal. If you look you'll see all kinds of weird things, the 60 day moving average just crossed the 175 day moving average. So what? Just wait a day, and if you want to play ma crossovers, the 50 will probably cross the 200 and you'll actually have a decent indicator.
Bottom line - people sometimes make up rules of trading to justify their moves. Its natural, its rationalization.
Every stock I post on that I said I've purchased, if you see it quick enough, its a buy recommendation. Unless I posted to sell it, then its a sell recommendation. I'll go ahead and take the blame for any money you lose, or win.
