METHODOLOGY
How PerpPulse Public Market Data Is Calculated
Definitions, timing, alert stages and limitations for the delayed public layer.
Market Universe
PerpPulse reads Binance USDⓈ-M futures markets that are USDT quoted, marked PERPETUAL, and currently TRADING in the explicit public catalog.
Snapshots and public timing
Metrics are based on persisted 2H snapshots. A public page is delayed by at least 24 hours. The snapshot timestamp identifies the persisted public data point; it is not a real-time exchange quote. Collection gaps and later repair may affect availability and sitemap timestamps.
Open Interest and changes
Open Interest is the outstanding futures exposure recorded for the snapshot. OI 2H, 8H and 24H compare the persisted values over those windows. Price changes use the corresponding persisted market values.
OI Flow Proxy
OI Flow Proxy is a derived PerpPulse indicator that combines changes in open interest with the observed price context. It is a nominal proxy, not measured capital inflow or a claim about trader intent.
Volume Ratio compares the current 2H quote volume with the symbol's historical reference window.
Alert stages
L1_WATCH, L2_PERSISTENT, L3_CONFIRM, and OI_FLUSH are persisted main alert transitions. WATCHING is a display retention state, not a raw alert stage.
Limitations
Public pages are historical and delayed. They may contain gaps or repaired snapshots, and they do not expose the paid archive or real-time detail projection. Nothing on PerpPulse is financial advice.
