The trade worked out fine, but it wasn’t an absolute stunner.
You can try to hedge using something like a strangle buy but the best bet is going to just close or use a mental stop to avoid any big volatility going into next month.
The main issue as to why this didn’t work as well is because the back month options had a big decline in implied vols. The nov 75 put started at 125% and is currently sitting at 113%, so that’s where a good chunk of the potential gains went.
