Costavo • Net Cost Tracking
Costavo Trading Ledger
Record every buy and sell in chronological order, settled automatically with the moving weighted-average method — figuring out, after subtracting realized gains/losses, what your true net cost basis is on what you're still holding. Manage multiple assets (stocks / crypto / etc.) at once, each tracked independently.

= (cost basis − cumulative realized P/L) ÷ remaining qty, with fees already factored into both cost and P/L. Selling above this price means the account is truly in the black overall.
