A word of caution here - I'm skeptical any of these backtest results are relevant to the current market. I'd be extremely careful about post-earnings condors right now since the potential for loss is so high. I've stopped doing any post-earnings condors several weeks ago after they all started showing losses. Each one had a really good looking backtest.
Personally, I'm inclined against. Even if VIX wasn't very high right now.. there's only 4 samples in the backtest. Not enough for a play as bold as a straddle without earnings to hold back theta.
I plan on looking at the Post Earnings ICs throughout the day and evaluating an early entry if I think they've stabilized.
