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 25+ 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 (2000+ 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 method 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.
