why do you have to be so honest and straight i should add one should have exit plan, ie for when trading plan stops working. You have to stop it and look for another edge. R&D is important for sustainability. Also, understanding why you have an edge will help to anticipate future... say coming of HFT changed things.
Not necessarily. If you're trading price, your edge never fails, which is not to say that there's anything magical about trading price, but that trading price necessitates learning how to trade in an environment of uncertainty (which I just wrote in another thread). Once one learns how to do that, the "plan" is tweaked in an almost continuous state. Therefore it never grows stale. At least unless and until the trader does. Which one hopes does not occur until one becomes feeble-minded.
Lol, sorry Daring but I don't "buy the dip" I have a propensity to fade this rally and the one system that I have under my belt is shorts only
