Recently I've done an experiment on having both long/short position(SSO/SDS) at the same time to trade the S&P index.
Instead of going completely long or short, I just adjust the ratio of the two position to get a net exposure.

Since I always have a position on the right side(though the strategy could be in -ve territory), psychologically I feel less biased when I have to flip directions, and more importantly , I would have less tendency sticking or adding to the losing positions. Somehow our brains are being short-circuited for X amount of time whenever we have a wrong position and more so when we are completely on the wrong side, and typically that's precisely when traders make irrational decisions, especially intraday.

In terms of commission, it doesn't make much sense but I feel that the psychological advantage is worth more than the comm I paid since I am not a HFT trader.
Most traders wouldn't do this due to comm but to me, the psychological disturbances cost me a lot more than comm historically. so net net still a +.

Just wondering if anyone here has similar practice?
