You are 100% correct about those put spreads not going much lower below .40c
The reason why I think it makes sense to take those off is because if the underlying moves higher and the bear calls gain 1.00 while bull puts lose .10c, these puts arent doing anything to help this position. I like the idea of rolling up the puts to 10-13 delta for additional credit if I think that the pull back, if it comes, will not be a massive move lower. Taking off bull puts and only holding on to bear calls is best if the underlying reverts, but the timing has to be perfect. There’s no right or wrong here, it’s about NET position delta. If you’re comfortable holding on to -X delta for a few days while waiting for reversion? If the answer is no, then selling another put a bit higher is the way to manage this position. This is my thinking process..
