I'm definitely not thinking I invented this, but I figured it out on my own. There really is no way to know if you if a stock went up/down unless you remember or write down the figures. A change of +6.50 is great, but if you check hours later and see +5.50, you'd think the stock was doing well unless you remembered the original number.
So all I'm doing is doing the opposite of everything. If I longed a stock with 50,000 shares, I short it with 1 stock. That way, if the short stock drops, I know I made money on the other one. Etc.
I know, ground breaking stuff
