BTC Dominance Tracker — 15 Market Cycle Analytics

The BTC Dominance Tracker delivers 15 computed analytics from a single run: dominance regime, dominance trend, altcoin momentum signal, ETH dominance ratio, DeFi vs BTC signal, cycle phase estimate, fear/greed proxy (0–100), rotation velocity, alt season probability, dominance momentum, capital rotation signal, market maturity signal, dominance vs price divergence, institutional preference, and trend confidence. Tracks the BTC.D chart equivalent in structured data form. No API key required. $0.005/run.

Why use BTC Dominance Tracker?

1. Altseason detection — The alt_season_probability score (0–100) and altcoin_momentum_signal classify current conditions in real time, enabling automated rotation decisions from BTC into altcoins at regime changes.
2. Cycle phase monitoring — cycle_phase_estimate classifies the current market regime (accumulation, markup, distribution, markdown) based on dominance dynamics and price behavior — macro context for any trading model.
3. Institutional vs retail rotation signals — institutional_preference and capital_rotation_signal flag when large-cap flows diverge from retail behavior — a classic leading indicator for trend reversals.
4. Portfolio rebalancing triggers — Use dominance_regime and portfolio_allocation_signal to build rules-based rebalancing that responds to structural market shifts rather than price volatility alone.
5. Historical dataset accumulation — Daily scheduled runs produce a clean time-series of all 15 signals for quantitative research on dominance regimes and their relationship to altcoin returns.

FAQ

How is alt_season_probability calculated? Combines dominance trend direction, dominance momentum, ETH dominance ratio, altcoin aggregate momentum, and the fear/greed proxy into a composite 0–100 score. Above 70 historically correlates with broad altcoin outperformance vs BTC. Use alongside price action and volume for confirmation.

What is dominance_vs_price_divergence and why does it matter? When BTC price rises but dominance falls, capital is rotating into altcoins even as BTC climbs — a classic altseason setup. When BTC dominance rises while price falls, it signals flight to relative safety within crypto. This flag captures regime-change moments automatically.

How does this complement the Altcoin Season Index? The Altcoin Season Index scores performance (% of top 50 outperforming BTC). BTC Dominance Tracker scores market structure (dominance dynamics, cycle phase, institutional flows). Use both together for highest-conviction regime signals.

Does this require any API keys? No — all data is sourced from public endpoints. No API key, account, or subscription is needed.
