Hi traders, What recourse, if any, do we have when we need to liquidate an open option position, but the market maker doesn't show up to work? All last week, the TF option market was perfectly liquid and orderly. Today, nobody is making that market. Is there any way to track down the market maker and call them? Do they post a schedule as to when they plan to grace us with a liquid market? In the meantime, anyone want to sell me some TF Jun 2010 645 Calls?
