One side effect of using too large of position sizes when trading is it causes a reluctance to close at a loss. A small loss quickly turns into a big loss. "I can't close it now I'll wait for a bounce to close." .. and it never bounces and the loss keeps growing and growing.
I have no read on the markets right now for the first time in a long time. Just a cluster of chop with random knee jerk reactions based on global news events but no real sustained momentum in either direciton.
