This is mighty fine:
2022-05-27 * "SELL PUT"
Expenses:Investments:Fees:Fidelity:RollIRA 0.0400 USD
Expenses:Investments:Commisions:Fidelity:RollIRA 0.6500 USD
Assets:US:Fidelity:RollIRA:AAPL220603P135 -1 AAPL220603P135
{18.00 USD}
Assets:US:Fidelity:RollIRA:Cash 17.31 USD
2022-06-03 * "EXPIRED PUT"
Assets:US:Fidelity:RollIRA:AAPL220603P135 1 AAPL220603P135 {} @ 0.00 USD
Assets:US:Fidelity:RollIRA:Cash 0.00 USD
Income:US:Fidelity:RollIRA:Pnl:AAPL
- I added cost basis
- I balanced the closing expiration with P/L income
Now, if you're going to do covered calls, you'll want to associate the
underlying trade(s) with the various covered call positions as they expire
and/or you roll them forward, because what you're ultimately doing is
lowering the cost basis of your long position, and it's nice to be able to
track the P/L of the entire sequence. Beancount is sufficient for that.
If you're going to do complex options trades with more complicated
scenarios, I'd recommend for those to use this instead:
https://github.com/beancount/johnny
I'm still working on exporting Johnny's database contents to Beancount -
probably with a single transaction per trade chain. It's easily done
though, a simple conversion from a CSV file to Beancount inputs should be
easy.
Another question is how to handle the 100x multiplier. I prefer to use -100
with 0.18 USD than -1 with 18.00 USD, but either way aren't great. Ideally
Beancount would handle that for you (it will eventually).
You might be interested in my notes on symbology:
