Closed (Margin): /MES February 28th 3740 Short Put

... for a 15.75 debit.

Comments: Filled this leg for a 24.25 credit. Closing it out here results in a realized gain of (24.25 - 15.75)/.2 = $42.50. I'll replace it with an appropriately delta'd short put higher up the ladder in a minute here ... .
