Market indicators
The four BlockMind market indicators — Fear & Greed, BTC Dominance, Altcoin Season, and the Contrarian Leverage Index — and how to read them sensibly.
BlockMind tracks four market-wide indicators at blockmind.app/market/indicators. Together they answer one question from four angles: what mood is the market in right now?
All four indicators update once daily. They are not real-time gauges — treat them as a daily reading of market temperature, not a live feed.
The four indicators
Fear & Greed Index
The classic crypto sentiment gauge, sourced from Alternative.me. It scores overall market sentiment from 0 (extreme fear) to 100 (extreme greed). Low readings mean the market is anxious; high readings mean it's euphoric. Historically, extremes in either direction have been more interesting than the middle.
BTC Dominance
Bitcoin's share of the total crypto market cap, via LunarCrush data. Rising dominance usually means capital is favoring Bitcoin over altcoins; falling dominance often accompanies risk-on rotation into alts.
Altcoin Season Index
A BlockMind in-house indicator: it measures how many of the top 50 altcoins outperformed Bitcoin over the last 90 days, scored 0 to 100. High readings suggest altcoins are broadly leading; low readings suggest Bitcoin is doing the heavy lifting.
Contrarian Leverage Index
A BlockMind in-house sentiment gauge built from derivatives positioning data via Coinglass — open interest, long/short positioning, and funding rates — scored 0 to 100.
The Contrarian Leverage Index is a sentiment score, not a signal generator. It does not emit buy or sell signals. An extreme reading describes how traders are positioned — it is never an instruction to act.
Free vs Pro
The Fear & Greed Index, BTC Dominance, and the Altcoin Season Index are included on the free classic platform. Pro includes all four.
If you're on Pro, your agent reads the same indicator data — you can ask it what today's readings mean for your holdings.
On each indicator page
Every indicator has its own page with:
- History — how the reading has moved over time, so you can see today's value in context.
- AI chat — ask questions about that indicator directly on the page: what it measures, why it moved, what similar readings looked like before.
How to use them sensibly
- Read them as context, not triggers. An indicator tells you the market's mood; it doesn't tell you what to do about it.
- Expect lag. All four update once daily and summarize what has already happened. They confirm conditions more often than they predict turns.
- Extremes can persist. "Extreme greed" can stay extreme for weeks in a strong trend, and fear can grind on through a long drawdown. An extreme reading is not, by itself, a reversal.
- Combine them. BTC Dominance plus the Altcoin Season Index together say more about rotation than either alone; Fear & Greed plus the Contrarian Leverage Index together say more about crowding than either alone.
These indicators are research inputs, not financial advice. Neither the indicators nor your agent will ever tell you what to buy or sell — the decision is always yours.
