Yeah, I guess I'm struggling with the decision because I don't have a strong basis for doing one or the other. Aside from my general attachment to modeling accurately, I can't think of anything I would actually do with the information that between 10:21AM and 10:25AM my order was executed in 20 different transactions at slightly different prices, versus one execution at the average price.
In the end, mostly because it seemed to be easier to implement, I ended up keeping the full transaction resolution through the ledger and booking, and only clustering transactions on the final 8949 report. This does mean that my individual lot booking reports remain verbose and complex though. On Tue, Aug 20, 2024 at 11:12 PM Martin Blais <[email protected]> wrote: > It depends on your goal.
