Lol, apparently, I could've pushed even more as the market continued crashing all the way to the close. I am trying to do a trade review and see if there's anything I can learn from this trade. It's mostly for me to dot the i's, so may not be worth reading.
I risked almost 3.7k on the trade and made about 2.2k, not great risk:reward as a stand-alone trade(at some point I was up 8k mark-to-market, still not a great R:R). However, if I look at this trade as a hedge for my fat-finger, I think it was a "success" - I was able to convert original naked put into a defined-risk trade, plus gave myself a chance to come out at break even or better. If I was not so obsessed with keeping the "lottery ticket," I think I would be able to close it at break-even much sooner (by choosing longer term short legs at higher strikes - my lowest short strike was $900!).
If I look at this trade as a poor man's covered put, I think it was a disaster. TSLA experienced so much volatility during this time, which is what I was expecting (after-shocks), but it took me soooo long to get to break-event. One of the reasons for this was that I tried to push the trade and was choosing weekly options for short legs in order to maximize the un-covered time in the market for the long leg. The Santa Clause rally really hurt my long leg and it was a "miracle" that I got to make any money on it at all.
As I mentioned before, the main "improvement" would be for the long leg to include earnings release. Other than that, I'm not sure how I could've improved it(we don't know what we don't know). I think people mentioned favorable skew, but I don't feel like there is enough edge there to rely on(I maybe way wrong on this). One thing I really hate about this trade is how much baby-siting it required. With long options, I always get pressured from the time ticking and I feel like it forces me to be less patient in waiting for a good spots to sell premium. Scaling would help with this, but I doubt it would make it much easier or profitable. I think I'm starting to understand why many people here just set up structures like butterflies in a set-it-and-forget-it fashion. The only reason I started experimenting with options it to be less involved with markets on a day to day basis, not more involved.
I still have two other "earnings plays" outstanding which are not going smoothly either, so let's see if they convince me to give up on this idea for good.
