QQQQ puts, sold them to book the profit

I sold my qqqq puts to book the profits. Todays volume to the downside was very very low. Also NDX ( Nasdaq 100 ) made a low and showed good strength later by not going back to the low even as the dow kept falling.
While the markets may go down a bit more, I think the overbought condition has been resolved and the risk/reward is to the upside .
But I am not buying yet, hopefully AMZN will come down more or maybe RIMM will.
Earnings season starts so we will have that going on.
