Spot PnL Metrics: Holdings, Breakeven Price, and Cost Basis
Summary
The document describes a spot-account PnL dashboard organized into account, coin, and trading analyses. Account and coin views report PnL over different periods alongside net inflows and outflows; trading analysis provides realized and unrealized PnL, fees, and pair-level activity. The guide explains that the coin performance view includes spot trades, conversions, and small-balance conversions, and defines transaction holdings as the trading-related position rather than all assets in the account.
A central distinction is between a trade breakeven price and an older asset cost-price measure. The former uses trading activity to update a weighted cumulative price and resets when transaction holdings reach zero; the latter includes asset inflows such as transfers and airdrops. The article supplies formulas and a worked BTC example showing how buys, sells, and savings transfers affect the two measures differently. These are accounting conventions for interpreting the dashboard, not a method for predicting prices or identifying profitable trades. Results depend on the stated data coverage, calculation start dates, and platform rules.
Key ideas
- The dashboard separates account-wide, coin-level, and trading-pair PnL views.
- Transaction holdings include spot trades and conversions, but can differ from total account holdings.
- Trade breakeven price is based on trading activity, whereas the older cost-price measure includes asset inflows.
- The breakeven calculation resets when transaction holdings fall to zero.
- The displayed metrics describe past account activity and do not predict future returns.
