The cryptocurrency market is known for its dynamic shifts in momentum, with periods where Bitcoin dominates and others where altcoins take the spotlight. Understanding these cycles can be crucial for traders and investors aiming to optimize their portfolio allocations. The Altseason Index (Top 10) is a powerful analytical tool designed to identify whether the market is entering an altseason—a phase where altcoins outperform Bitcoin—or a Bitcoin season, where BTC reclaims its dominance.
This guide dives deep into how the index works, how to interpret its signals, and how it can be integrated into your trading strategy for better decision-making.
What Is the Altseason Index (Top 10)?
The Altseason Index (Top 10) measures the relative performance of the top nine altcoins against Bitcoin over a 90-day period. Inspired by the well-known Blockchain Center Altcoin Season Index, this version focuses on major digital assets including Ethereum (ETH), Binance Coin (BNB), Cardano (ADA), XRP, Solana (SOL), Polkadot (DOT), Avalanche (AVAX), Shiba Inu (SHIB), and Chainlink (LINK).
By tracking how many of these altcoins outperform BTC, the index provides a clear visual signal of market sentiment and capital flow trends across the crypto ecosystem.

How the Altseason Index Works
The index uses a simple yet effective methodology to determine market phases:
Step-by-Step Calculation:
- Price Change Analysis: It calculates the 90-day price change for Bitcoin and each of the nine selected altcoins.
- Performance Comparison: For each altcoin, it checks whether its price increase exceeds that of Bitcoin over the same period.
Index Score Formula:
$$ \text{Index Value} = \left( \frac{\text{Number of Outperforming Altcoins}}{9} \right) \times 100 $$
Market Phase Classification:
- Above 75: Indicates an altseason — green zone.
- Below 25: Suggests a Bitcoin season — red zone.
- Between 25 and 75: Neutral market conditions.
This scoring system allows traders to quickly assess whether capital is rotating into altcoins or consolidating in Bitcoin.
Visual Representation and Chart Integration
When applied to a chart, the Altseason Index offers intuitive visual cues:
- Blue Line: Represents the current index value (ranging from 0 to 100).
- Green Horizontal Line at 75: Marks the threshold for altseason.
- Red Horizontal Line at 25: Indicates the start of a Bitcoin-dominated phase.
- Colored Backgrounds: Green shading highlights altseason zones; red reflects Bitcoin seasons.
These visual elements make it easy to spot trend reversals and potential entry or exit points without complex analysis.
Traders typically apply this indicator on daily charts, though it can also be adapted to other timeframes depending on trading style—swing traders may use 4-hour charts, while long-term investors rely on weekly data.

Practical Usage: When to Buy Altcoins or Hold Bitcoin
Understanding the index’s output can directly influence investment decisions:
✅ Consider Altcoin Investments When:
- The index rises above 75, signaling strong momentum in the altcoin market.
- At least 8 out of 9 major altcoins are outperforming Bitcoin.
- Market sentiment turns speculative, often driven by new narratives like DeFi, NFTs, or layer-1 innovations.
During such phases, diversified exposure to high-conviction altcoins may yield higher returns than holding BTC alone.
✅ Focus on Bitcoin When:
- The index drops below 25, indicating risk-off behavior.
- Most altcoins are underperforming, suggesting capital flight to safety.
- Macro conditions are uncertain (e.g., regulatory pressure, macroeconomic downturns).
Bitcoin often acts as a safe haven during volatility, making it a preferred asset in bearish or consolidating markets.
Limitations and Important Notes
While highly informative, the Altseason Index has certain constraints users should be aware of:
- Limited Altcoin Scope: Due to technical limitations on TradingView’s
request.security()function, only nine altcoins are included. This excludes smaller-cap coins that might also exhibit strong performance. - Lagging Indicator Nature: Since it relies on 90-day price changes, the index reflects past performance rather than predicting future moves.
- Exchange-Specific Tickers: Users must ensure correct ticker symbols based on their exchange (e.g.,
BTCUSD,BINANCE:BTCUSDT) for accurate readings.
Despite these limits, the index remains a valuable tool when used alongside other technical and on-chain metrics.

Frequently Asked Questions (FAQ)
Q: What does an Altseason Index above 75 mean?
An index value above 75 means that at least seven or more of the top nine altcoins have outperformed Bitcoin over the past 90 days. This typically signals an altseason, where investor interest shifts toward alternative cryptocurrencies.
Q: Can I use this index on any trading platform?
The Altseason Index is primarily designed for TradingView, where it can be implemented as a custom script. While similar logic can be replicated elsewhere, full functionality—including real-time updates and visualization—is best achieved within TradingView's environment.
Q: Does a high index guarantee profits from altcoins?
No. While a high reading suggests favorable conditions for altcoins, it doesn't guarantee future gains. Always combine the index with fundamental analysis, risk management, and broader market context before making trades.
Q: Why are only nine altcoins included?
This limitation stems from TradingView’s technical restrictions on cross-asset data requests (request.security()). The selected coins represent some of the largest and most liquid altcoins by market cap, ensuring meaningful benchmarking.
Q: How often should I check the index?
Checking once per week is sufficient for most investors. Daily fluctuations may occur, but the 90-day window smooths out noise, so focus on sustained moves above or below key thresholds.
