Funding Rate Alerts
Funding rate arbitrage detection across 7 exchanges
The Funding service scans funding rates across seven exchanges every 60 seconds. It detects delta-neutral arbitrage opportunities — both cross-exchange perp-perp and single-exchange perp-spot hedges — within 30 minutes of settlement. Post-detection monitoring tracks rate changes until funding settles.

How It Works
How Funding Rate Alerts Works
CryptoGrind reads funding rates from Redis (populated by the CEXFeeds metadata service) for all perpetual contracts across Binance, Bybit, MEXC, Gate.io, BingX, Hyperliquid, and Aster. Every 60 seconds, the detector filters pairs approaching their next funding settlement (≤30 min), computes the funding rate differential (ΔF) for every valid exchange combination, and checks if ΔF exceeds trading fees multiplied by a safety multiplier. Alerts include the optimal long/short direction, entry spread from real-time NATS prices, expected PnL, and a safety ratio.
Technical Detail
The scan cycle processes ~989 base symbols across 7 exchanges in under 80ms. Cross-exchange matching uses combinations(eligible, 2) with ±60s timestamp synchronization tolerance. Entry spreads are computed from live NATS price cache (arbiter.prices.v1). Interval normalization scales ΔF to a common 8h base for fair ranking across exchanges with different funding intervals (1h, 4h, 8h). Cross-alias matching handles symbols like 1000PEPE ↔ PEPE via exchanges.toml multipliers.
Features
What's Included
Cross-Exchange ΔF Detection
Compare funding rates between any two exchanges. Long on the lower rate, short on the higher. Delta-neutral by construction.
Perp↔Spot Hedge Capture
When a single exchange has a high funding rate, hedge with spot on the same exchange. No cross-exchange transfer needed.
Post-Alert Rate Monitoring
After detection, the system monitors rates for 30 minutes post-settlement. Severity escalation (INFO → WARNING → CRITICAL) if the edge deteriorates.
Safety Ratio & PnL Estimation
Every alert shows how many times the edge covers fees (safety ratio) and expected PnL including entry spread. No guesswork.
Use Cases
How Traders Use This
Funding Rate Arbitrage
Long on Exchange A where the rate is negative (you receive funding), short on Exchange B where the rate is positive. Collect the differential at settlement. Repeat every funding cycle.
Spot Hedge Funding Capture
When funding is heavily positive on an exchange, short the perp and long the spot on the same exchange. No directional exposure, pure funding income.
Cross-Interval Ranking
Compare opportunities normalized to 8h base. A 0.01% edge on a 1h interval is equivalent to 0.08% on an 8h interval — 8x more settlement events per day.

FAQ
Frequently Asked Questions
Common questions about Funding Rate Alerts.
Funding settlements happen every 1-8 hours depending on the exchange. Alerts fire within 30 minutes of each settlement when the rate differential exceeds fees. During volatile markets, dozens of opportunities can appear per funding cycle.
For cross-exchange arbitrage, yes — you need funded accounts on both the long and short exchanges. For spot hedge, a single exchange account with both perp and spot is sufficient.
Profitable opportunities typically range from 0.1% to 2% per funding cycle after fees. The safety multiplier (2x by default) ensures the edge comfortably covers round-trip trading costs.
