Cost-basis method, explained
When you own shares bought at different prices and sell only some of them, a cost-basis method decides how the sale is priced — FIFO prices against the oldest shares, LIFO the newest, average cost blends every buy into one running price, and specific-lot lets you name the exact shares. sizeforzero computes realized P&L with weighted-average cost for every account today; FIFO, LIFO, and specific-lot accounting aren’t available yet.
Where cost-basis method shows up in a journal
A trading journal is where this stops being a definition and becomes your own number. sizeforzero computes it from the trades you import or log, alongside the rest of your analytics vocabulary, and every figure in the app carries an (i) that explains it in the same plain English you just read.
