Could it be investors or intitutional investor had put a spread trade. The calls were very active and I would suspect someone had put on a spread trade. Selling a handful of covered call in the $3.30 and higher. Then buying the $2 calls when the price is below $3 making .it hard for the shares to go up or down but settling out at $3. The person would also hold alot of cash if goes much lower thus having the $2 excersiable. So now you know what could be happening. Or you can chat with freewilly about stupid things but thinking he knows everything.
