Oh, you could have reversed your position. If you were long you could have sold some to save your margin from being liquidated. I learned this the hard way also. I have done the same mistake, but this time was able to save myself from liquidation. You don't need more collateral, you just have to adjust your position on your margin. Yeah it's going to set you to some unreachable amount, but at least you still have a chance to gain back close enough to where you don't liqudate.

 I feel for you tremendously man, I support you, because we're no Eskimo brothers in this blood bath.  #yunk
