What call activity means in Radian

optionMONSTER systems show that a trader sold 4,050 January 2015 15 calls for $3.20, below the listed bid price at the time, in volume that was far above previous open interest of just 710 contracts. Seconds later, a block of 2,625 January 2014 10 calls traded for $4.80 against open interest of 16,481 at that strike.
This could be a new diagonal spread, which would be bullish up to $15 in the long term. But this could also be a roll of a short-call position, with the trader buying back the now in-the-money 10 contracts and selling the longer-term 15 calls. (See our Education section)
