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.

For IRYSUSDT, 10,000 USDT of notional × -0.012688% gives 1.2688 USDT over the quoted 1h rate period: longs receive and shorts pay.
