No metric.  No strategy.  Just selling at the money calls.  If I get shares called away I reload the next week and sell calls again.  I may try to avoid selling calls on big down days or reloading on big up days but other than that no real timing on buying shares or selling the calls.

are they really ATM or are they $1 or $2 OTM?
