Advanced weighted-averaging methodology.
Windy uses a sophisticated three-phase system to calculate reliable USD rates for thousands of cryptocurrencies. Our methodology aggregates data from 100+ exchanges using intelligent weighting based on spread quality, trading volume, and data freshness — ensuring manipulation-resistant, institutional-grade pricing.
Three-Phase Pipeline
Sequential calculation: Phase 1 (Stablecoins), Phase 2 (BTC/ETH), Phase 3 (2,000+ tokens) — preventing circular dependencies and ensuring rate accuracy.
Multi-Factor Weighting
Every data point receives three independent weights: Spread (liquidity quality), Volume (market significance), and Time (data freshness under 30 seconds).
Manipulation Resistance
Our multiplicative weighting requires attackers to fake tight spreads AND high volume AND fresh data simultaneously — making manipulation economically infeasible.
Automated Quality Control
No manual exchange whitelists needed. High-quality, liquid exchanges naturally dominate through data-driven weighting with full audit trails for every rate calculation.
Weighted aggregation
Per-tickEach price contribution is multiplied by three independent weights. Faking the rate requires faking all three at once.
