Well, the position closed for 0.01 as well, although I had offered a limit order of 0.02. Not sure if I will do another trade like this risking some of my long term hold stock for small reward - but it is learning.
Also, Fidelity does not charge a commission for trades like these for pennies. So I paid a commission of 1.30 when I sold the calls, but nothing when it was closed with a buy to close.
I find that my risk tolerance with covered calls is dramatically lower than the put side. I'm selling .15 - .30 delta puts, but get itchy on .05 calls when I have a move against them too far from expiration.
The observation about learning though is the key to me. I started out with .05 delta puts and have been learning for 3 months now. I've been learning about how much risk I can tolerate each side, how to manage (close) positions early so I can open a replacement, and a lot more. The net result is that in a significantly less friendly environment today compared to March, I'm getting about 3x/month over when I started.
I also remind myself regularly that we haven't been through a sharp move up or down during this period, so it's easy to develop a false idea of how badly this can work.
One of the things you can learn is "that was way too nerve wracking - I'm not doing that again".
So far I've learned about max pain and OI walls to spot share price resistance levels, up and down, that will be hard to breach for very short term options (roughly the final 3 days of trading). One method I've used to handle the risk on the call side is I go find the .05 - .08 delta option (usually the next expiration) - and therefore small premium. Then I go compare that to the particularly active strikes, and I make sure I've got 2 OTM active strikes between me and the share price (and go out to the 2nd OTM big strike if needed) AND THEN I go out 1 more strike (thus the 1005 instead of the 1000 strikes for today).
On my list of things to learn more about are Bollinger Bands - this seems to be the key thing that @Artful Dodger uses for spotting the weekly closing price so far ahead (or at least, he seems to be pegging them way better than me, and better than most).
