Mail Block: Open Interest Question:

I am entering the world of trading weekly options. With monthly options I have been told to make sure there is at least 100 open interest when I consider buying an option. I'm noticing some of the weeklies I'm considering don't have much open interest even though they perform well in my back testing. My question is. If there is little or no open interest, is there a chance I will not be able to sell my option. Even at the bid price?

Around the Block: Looking to see if the vol can expand a little more - waiting for the bulls to come back. Keeping an eye on initial claims given the weak jobs number. Alcoa earnings 4/10, Google earnings 4/12.
