You have to have level 2's. I see every bid and ask in real time so when someone throws a very high buy, I sell within 5 seconds. When they throw a very low sell, I buy within 5 seconds. Rinse repeat. Like right now that .253 average from yesterday is looking great at .2641. That's a 1 cent gain again in one day on 35k shares. It's nickle and dime trades to keep me sharp for when the real spikes come. Beats a real job, cycling monthly rental monies into this to maximize rents. Credit lines I use for dry powder. Its tax deductible too lol.
