I closed some of the calls I'd written.

I appreciate you sharing. I have yet to close my Jan contracts I wrote back in August and early September.

FWIW, my decision to close was not just because I'm quick to take a small profit. (a terrible sin which I am sometimes guilty of)
My thinking and often experience is that by closing them early for a good-enough profit, that leaves me the "firepower" to do it all again if the stock price rebounds in the next while.
And of course, having received 80% of the pie already, the effective rate of return on the last 20% is pretty uninteresting.
I can get a higher return on that money as a cash deposit.
(I think my broker deducts short-option liabilities from the cash which is eligible for interest)
