The 24-hour card is not total P&L

Applying each asset's market change to current holdings estimates short-term movement. It does not know the acquisition price, holding period or every cash flow and must not be labeled lifetime profit.

Tracked history establishes a baseline

Portfolio snapshots record value through time. Detected deposits, withdrawals and connection-scope changes are used to avoid treating added capital as investment profit.

Coverage must travel with the number

Exchange APIs can expose incomplete historical windows. ChainsFlow reports coverage limitations so an exact-looking percentage is not presented as more reliable than its inputs.
