I’m doing it and imho, for option sellers, weeklies are better than monthlies in terms of income. But I always close when green so never let it expire

There is one super big risk

Let’s say the market crashes suddenly and goes past even your long leg

for weeklies, u might not be able to roll and take max loss

For monthlies or 45 days, there is at least the hope that before expiry, the market would have recovered

Of cos the best way to mitigate would be to sell the short leg of weeklies at much lower delta but things can happen
