The cumulative rate sums actual settlements with known periods. Positive totals mean net payment by longs and receipt by shorts; negative totals reverse the direction. If notional value changed, multiplying the current position by this total will not reproduce account cash flows. Historical rates do not predict returns.
What does this rate mean for a 10,000 USDT position?
For BTCUSDT, 10,000 USDT of notional × 0.004112% gives 0.4112 USDT over the quoted 8h rate period: longs pay and shorts receive. This is a constant-rate illustration, not a settled bill or a forecast. Use the actual settlement rate and notional at each settlement; leverage is not multiplied again. Trading fees are separate.
