SN vol arb. 5K peak PNL; $300 haircut. $40 tail risk.
There was a wager thread on the professor's thread (put seller) and he lost/left. I posted an ES skew lock that required $38K on $35K req. Adding to the position with the COB order allows virtually unlimited size to hit the tape. Visualizing the trade stress and meeting one condition eliminates Dvega/Dvol risk. If the curve is above X = arb.

Looks like you found the holy grail. I have no idea how you did that, but here's what I am thinking:
1. In order to have zero BP reduction, the position must be completely covered. You can't have any uncovered short legs. Also a requirement for the position to be considered an arbitrage. With that kind of size, it had to be completely covered.
2. SN implies one underlying.
3. It's possible to sell vertical spreads to collect a credit, but that would result in a buying power reduction unless you were able to receive the full width of the spread as credit.
4. It's not possible to put on a long calendar or diagonal for a credit unless you legged into it after the market moved. In which case, you could have just closed the position for a profit instead of converting it to a risk-less position. Maybe the position was too illiquid to close efficiently. Short calendar / diagonal not possible without significant BP reduction.
Regarding the 2nd trade, you state that you could have entered the trade as a COB-order which I find hard to believe that such an extreme level of market inefficiency exists. Further, since you state that you legged into the trade, that implies that the inefficiency had to exist for a length of time suitable to manual (non-automated) trading. Looks like the trade started as a very deep ITM put butterfly.
In any case, nice trades!
