Services
Funding Rate Alerts
Funding rate arbitrage detection across 12 exchanges
The Funding service scans funding rates across twelve 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, Bitget, OKX, HTX, KuCoin, Phemex, 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 structurally implied long/short direction (the side that pays vs receives funding), the entry spread from real-time NATS prices, the estimated edge contribution, and a safety ratio. No outcome is implied — funding rates change every settlement, and observed edges are descriptive, not predictive.
Technical Detail
The scan cycle processes base symbols across 12 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 Monitoring
When a single exchange has a high funding rate, the perp leg can structurally be paired with spot on the same exchange — no cross-exchange transfer required. CryptoGrind surfaces these structures; execution and risk management are user-side.
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 & Edge Sizing
Every alert shows how many times the rate edge covers expected trading fees (safety ratio) and the estimated edge contribution including entry spread. These figures are descriptive of the rate snapshot at alert time and do not project realised PnL.
Use Cases
How Traders Use This
Cross-Exchange Funding Differential
When two exchanges show opposite funding signs on the same asset, the structurally implied position is long on the side receiving funding and short on the side paying it — a delta-neutral construction. Realised outcomes depend on fees, liquidation risk, transfer timing and counterparty risk on both venues. Informational content, not a recommendation to trade.
Spot Hedge Funding Structure
When funding is heavily positive on an exchange, a short perp + long spot structure on the same exchange is market-neutral on the directional component. Funding flows, fees, liquidation and counterparty risk determine the net outcome — informational content, not a projection of returns.
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.
Observed cross-exchange funding deltas vary widely with market conditions and are not indicative of future results. The safety multiplier (2x by default) is a display filter that surfaces alerts whose observed delta exceeds round-trip trading costs — it is not a prediction of outcomes. Informational content only.
