From April to July I completed 12 IC's and won on 11. You place them when volatility is high and and choose your short strikes wisely. If you choose 5 delta short strikes you'll have a high percentage low payoffs. My dozen were mixed between 10 and 43 DTE at deltas between 13 and 22. The other key to winning at IC's is adjusting to which there are numerous approaches: rolling the wings, rolling the short strikes or doing nothing.
