Superb play! Which parameter do you use for looking into IV (170%, in your case)?? I use thinkorswim and other portals and there seems to be several IV parameters..like IV Percentile, just IV, IV rank etc.

Thank you! Didn't really scan this trade though, just based off trading experience. I know by head all the stocks $TSLA, $ROKU, etc that usually have crazy IV before earnings and just crush the day after and $NFLX was one of them. Implied move on $NFLX was 10-20% yesterday so I placed the short call at the mid of that. Also I usually only sell premium on indexes but occasionally earnings trades,  so $SPY, $DIA, $QQQ, I do that based off the $VIX.
