I agree. I had one almost perfectly pin yesterday. Bot 1:2:1 4380-4395-4410 put fly @ $3.70 around 2:15 pm. Went off the board at 4395.65 about as good as it gets for 45 minutes worth of work. Cash settle this morning at $1436 or a 388% return. If only I had the balls to size up. Thinking about on winning M,W,F taking half the profits and playing these flies in the last ten minutes. But damn that $5 exercise fee. I've only traded a one lot on this fly is it $5 per option for the settlement or just $5 overall regardless of size?
When I traded it, it was a flat fee no matter how many contracts you had and I was trading 8 or 16 contracts depending on the width of spread. I had good profits in 2016 and 2017 but I started taking a lot of max losses early in 2018 so I paused and never got back to it.
