Data Sources
Where we get our data. All metrics have fallbacks when APIs fail.
Methodology
• Dashboard refreshes every 5 minutes. APIs have their own cache (5m–24h).
• Sentiment combines DXY, Fear & Greed, ETF flows, miner cost, realized price, MVRV, funding rate.
• Composite Index: Tier-based weights. Hard (on-chain): MVRV, realized, miner, exchange flows, whale. Market: DXY, ETF, funding. Survey: Fear & Greed. Soft (low weight): News. Bearish = negative score.
• 7-day prediction uses heuristic: Fear & Greed (contrarian), funding (contrarian), 24h momentum.
• Key levels are derived from realized price and miner cost.
