Open interest should be going down and not up, IMHO. Perhaps, the market makers are too busy to cancel positions until the end of the day. So a buy order for 100 calls and a sell order for 100 calls instead of canceling, add up to an open interest of 200 calls. This is just a guess.

Does anyone know how to find out whether an open interest of 10,000 calls means the public is long the calls or short the calls? Is there any way of finding out? Can individual market makers be short and long and the open interest is just the absolute sum of their positions? Enquiring minds would like to know.
