Record BTC, ETH and SOL trades locally with direction, entry, exit, quantity and costs. Review net P&L and export a workspace backup.
Compare depth-adjusted spot spreads, model perpetual funding and inspect trading assumptions. Enable JavaScript to open the complete BTCMox workspace. The calculators work locally; live quotes require access to public provider APIs.
Every tool is provided as a separate HTML page with a stable address. JavaScript adds the interactive workspace; public data is optional.
Record a closed trade with its asset, long or short direction, entry, exit, base quantity, total costs and a short note. The journal calculates net P&L from those inputs. Records stay in browser storage and can be removed or backed up from settings.
Use the same quote currency and cost conventions when comparing records. Total costs should reflect the fees and other expenses relevant to the result. Imported journal P&L is recalculated from validated trade inputs so a supplied total does not override the underlying arithmetic.
A profitable trade can still violate a risk rule, and a losing trade can follow a sound process. Notes preserve the research context. For aggregate expectancy, profit factor and an equity/drawdown series, use the separate trade-journal performance analyzer with a local CSV.
