Market Breadth measures how many of the top coins by market cap are advancing versus declining over 24h, 7d and 30d.
A high breadth score means participation is wide; a low score means the move is narrow or defensive.
What does it measure?
Universe: top ~250 coins by CoinGecko market cap.
Breadth score = advances ÷ (advances + declines) × 100, ignoring near-flat coins.
A/D ratio, median/average change and gainer/loser lists add context.
How to read it
Strong (≥70%): broad participation — bullish moves look healthier.
Thin (<30%): few coins carry the tape — risk of fakeouts or BTC-only rallies.
The green/red bar shows advance vs decline vs unchanged share of the universe.
Switch windows to separate short bursts from multi-week trends.
Using Market Breadth on PEPS Crypto
Pick 24H / 7D / 30D, read the dial regime, then scan context cards.
Open Sector Performance and Narrative Performance for theme participation.
Cross-check Total Market Cap and BTC Dominance for macro context.
Use gainers/losers as a quick tape of leadership.
How it works
- Data refreshes about every 30 minutes from CoinGecko markets.
- Flat threshold is ±0.05% around zero.
- Regimes: Strong ≥70, Healthy ≥55, Mixed ≥45, Weak ≥30, else Thin.
- Previous/delta compare against the prior PEPS snapshot for that window.
- History chart needs at least two snapshots.
What to consider
- A BTC-led rally can print weak breadth even if BTC is green.
- Weekend liquidity can exaggerate breadth swings.
- Always confirm with volume and flow tools.
- Gainers/losers are not trade recommendations.
- Combine with Market Stress for risk context.
Frequently asked questions
- What is a good breadth reading?
- Healthy bull markets often sustain breadth above ~55–60%. Sub-30% with rising indices can signal a narrow, fragile advance.
- How is this different from Altcoin Season?
- Altcoin Season on PEPS is a flow/attention proxy. Market Breadth is a price participation count across the top market-cap universe.
- Why are some coins missing?
- Coins without a valid change for the selected window are skipped. The universe is capped near the top 250 by market cap.
Conclusion
