This is getting to be a regular, last minute trade for me. I wait until the last hour or so of the day of expiration and look for resistance levels that day and the day or so prior. Then I set up a bear call vertical spread on an upswing, looking to get around $0.20 - $0.50 premium, by picking a strike that is around .20 delta or under which is often 10-20 points above those resistance levels.
