It depends how capitalized you are; if you can take some more heat there's a good chance you will see a decent pullback given how bullish this market is long term and can recoup 50% of your losses. Technically, it's not over for you yet but it's a worry because this move south looks to be the start of a decent correction—300 points on the S&P, which is no doubt why you're here asking for help.
...and if you followed the news and economic data, you would've known there was a high probability the manufacturing data was going to be weak. I think I posted a few weeks ago also that this post-Christmas move up will likely see a lot of investors get burned.
Thanks love the trade.
Monday will try to recover loss or will close
