The cryptocurrency market moves in cycles—sometimes dominated by Bitcoin, and at other times, altcoins take the spotlight. Knowing which phase the market is in can significantly improve your investment decisions. The Altseason Index (Top 10) is a powerful analytical tool designed to help traders identify whether we’re entering an altseason or a Bitcoin season. By measuring the relative strength of major altcoins against BTC, this indicator offers timely insights into shifting market dynamics.
Whether you're a seasoned trader or just getting started, understanding this index can give you a strategic edge in portfolio allocation and timing.
What Is the Altseason Index (Top 10)?
The Altseason Index (Top 10) evaluates whether altcoins are outperforming Bitcoin over a 90-day period. It tracks the price performance of nine leading altcoins—Ethereum (ETH), Binance Coin (BNB), Cardano (ADA), XRP, Solana (SOL), Polkadot (DOT), Avalanche (AVAX), Shiba Inu (SHIB), and Chainlink (LINK)—relative to Bitcoin.
Inspired by the well-known Blockchain Center Altcoin Season Index, this version streamlines data analysis with clear thresholds and visual cues, making it easy to interpret directly on your trading chart.

How the Altseason Index Works
The mechanics behind the index are simple yet effective:
- Performance Comparison: For each of the 9 selected altcoins, the script calculates their 90-day price change and compares it to Bitcoin’s同期 performance.
- Count Outperformers: It counts how many altcoins have delivered higher returns than BTC during that window.
Index Calculation: The final index value is derived using the formula:
$$ \text{Index} = \left( \frac{\text{Number of outperforming altcoins}}{9} \right) \times 100 $$
This results in a score between 0 and 100, reflecting the strength of altcoin momentum relative to Bitcoin.
Interpretation Thresholds
- Above 75 (Green Zone): Strong signal of altseason — most altcoins are outperforming BTC.
- Below 25 (Red Zone): Indicates Bitcoin season — BTC is leading the market.
- Between 25 and 75 (Neutral Zone): Market is mixed; no clear trend dominance.
These thresholds allow traders to make informed decisions based on prevailing market conditions.
Visual Design and Chart Integration
The indicator uses intuitive visual elements for quick interpretation:
- Blue Line: Represents the current index value (0–100).
- Green Horizontal Line at 75: Marks the threshold for altseason.
- Red Horizontal Line at 25: Signals the start of Bitcoin season.
- Colored Background Fill: Green shading appears when the index exceeds 75; red fills below 25, enhancing visibility.
Traders can apply this overlay directly on platforms like TradingView, where it integrates seamlessly into technical charts. While optimized for daily timeframes, it remains functional across various intervals—from 4-hour to weekly views.

Frequently Asked Questions (FAQ)
What defines an "altseason"?
An altseason occurs when a significant number of altcoins outperform Bitcoin in terms of price growth over a sustained period—typically 30 to 90 days. This often happens after a major Bitcoin rally stabilizes, allowing capital to rotate into riskier but potentially higher-return assets.
Why only 9 altcoins in this index?
Due to technical limitations on TradingView’s request.security() function, the script is capped at analyzing nine assets. However, these are carefully selected based on market cap, liquidity, and ecosystem influence—ensuring broad representation of the altcoin market.
Can I use this indicator on any timeframe?
Yes, though it's best suited for daily charts. Shorter timeframes like 1-hour or 4-hour may produce noisy or misleading signals due to volatility. Weekly charts offer broader trends but less timely entry points.
Does a high index guarantee profits in altcoins?
Not necessarily. While a reading above 75 suggests favorable conditions for altcoins, it doesn’t guarantee individual coin performance. Always conduct due diligence and combine this tool with fundamental analysis and risk controls.
How often should I check the index?
Reviewing once per week is sufficient. Since it measures 90-day performance, daily fluctuations won’t drastically alter its signal. Use it as a strategic guide rather than a short-term trading trigger.
Is the script free to use?
Yes, the original creator has released it as open-source on TradingView, allowing traders to view, verify, and customize the code. However, redistribution must comply with TradingView’s House Rules.
