Crazy sell-off today

Wow.. Dow loses more than 350 points today. What a crazy market, oil keep surging, all economic data looks bad. I bet a lot of investors lose their money, mine's included. When you think the market has rebound, you are wrong. I should keep shorting but now I have no more money left to play any stock and I don't want to deposit more money either. O well I guess we will just see how the rest of my options play out.
