Quote from illiquid:
Today there was really nothing that cried out clear and loud for an entry, yet somehow I managed to post my highest volume in a week. But actually, this is typical of my trading if I'm not careful; it's only recently I've realized the reason why my volume has a strong negative correlation with my p/l. Even if your best bet is sitting on your hands and doing nothing, being a discretionary trader, your subjective take on any situation has the ultimate say. If there aren't really any premium setups to be found, my mind tends to "work harder" in finding them -- not beer but boredom/frustration goggles. Secondary and tertiary plays suddenly seem like sure things; I throw my equity upon these at two to three times their deserved size, for lack of anywhere else go. With no true confidence in these trades I'll inevitably get shaken out easily, and promptly sucked into the next one even more readily from frustration. A bad vicious cycle to say the least. In contrast, when I'm lucky enough to exhaust my buying power early on in well-timed positions, I find there really is nothing left to do but sit and wait patiently for a decent exit. Volume peters out to nothing, my hands go limp -- I'm spent already. Now if only I could consistently register low volume on days when they really deserve it: when there is nothing to do. Realizing that the bulk of my volume comes from misguided intentions, well, that's something I discovered way too late in the game, and old habits are just that much harder to fight.
I think it's great that you've reflected and realized a weakness in your trading. This will inevitably make you a better trader. The question is, what steps are you taking to minimize/overcome the negative effects of overtrading?
