Currently while the market is open and traders are playing the market, the options chain to buy and sell contracts is not working.
I have no idea how something like this after a merger of Schwab getting ThinkOrSwim is able to happen. You are basically buying a contract and not able to close it right now. It is absolute insanity.
Someone tweeted that the CBOE System is down. But what are they going to do about the open contracts?! Are people just stuck losing money?
