I think they get bailed out by some company ... they have too many secrets to go down ... Its not just Knight that breaks the SEC laws .. they are just the largest, if they go down there will be whistle blowers .. then the SEC will be investigated for knowing and allowing these acts .. then the SEC will blame another agency .. and so on .. JMO.
I am happy with my profits shorting this pig BUT got out at the end of the day .. it could bounce and burn the shorts to their bones if they get funding. too many emotional traders in this and that breaks trading rule #1..
I hope your position, whatever it may be gains you tons of green my friend.
