How the Altseason Index Works
The mechanics behind the indicator are simple yet effective:
- Performance Comparison: For each of the 9 selected altcoins, the script calculates the percentage price change over the past 90 days.
- Bitcoin Benchmark: It simultaneously calculates Bitcoin’s 90-day price change.
- Outperformance Count: The number of altcoins that have outperformed Bitcoin during this period is counted.
- Index Calculation: The final index value is derived using the formula:
Index = (Number of outperforming altcoins ÷ 9) × 100
This results in a score between 0 and 100, representing the strength of altseason momentum.
Interpretation Thresholds
- Above 75 (Green Zone): Strong altseason signal — most altcoins are outperforming BTC. This may indicate growing investor appetite for higher-risk, higher-reward assets.
- Below 25 (Red Zone): Bitcoin season — BTC is outperforming nearly all major altcoins. Often seen during market uncertainty or early recovery phases.
- Between 25 and 75 (Neutral Zone): Mixed market sentiment. No clear dominance; traders should proceed with caution and look for additional confirmation signals.
These thresholds help filter noise and provide actionable context for portfolio allocation.
Visualizing the Market: Chart Features Explained
The Altseason Index comes with intuitive visual elements designed for quick interpretation on any TradingView chart:
- Blue Line: Represents the current index value (0–100).
- Green Horizontal Line at 75: Marks the threshold for entering an altseason.
- Red Horizontal Line at 25: Indicates the start of a Bitcoin-dominated phase.
- Colored Backgrounds: Green shading highlights altseason zones; red shading shows Bitcoin seasons, making trends instantly recognizable.
This visual clarity allows both novice and experienced traders to assess market conditions at a glance without needing deep technical analysis.
Practical Use Cases for Traders and Investors
Understanding when to rotate between Bitcoin and altcoins can significantly impact returns. Here's how different types of market participants can use the Altseason Index:
For Long-Term Investors
When the index rises above 75, it may be a strategic moment to increase exposure to high-potential altcoins. Conversely, when it drops below 25, reallocating toward Bitcoin could preserve capital during risk-off periods.
For Active Traders
Day traders and swing traders can combine the index with technical setups on individual coins. For example, entering long positions in strong-performing altcoins during confirmed altseasons increases the odds of catching upward momentum.
For Risk Management
The neutral zone (25–75) suggests indecision in the market. During these periods, reducing leverage or diversifying across sectors may be prudent until a clearer trend emerges.

Limitations and Considerations
While powerful, the Altseason Index has some important constraints:
- Limited Altcoin Coverage: Only nine altcoins are included due to TradingView’s
request.security()function limits. While these represent some of the largest and most liquid projects, they don’t capture the full breadth of the altcoin market. - Timeframe Sensitivity: Best used on daily charts for reliable signals, though it can be applied to other timeframes with adjusted expectations.
- Lagging Indicator: As a 90-day rolling measure, it reflects past performance rather than predicting future moves. Always pair it with real-time technical and on-chain analysis.
Despite these limitations, its transparency and simplicity make it a valuable addition to any trader’s toolkit.
Frequently Asked Questions (FAQ)
Q: What exactly qualifies as an "altseason"?
A: An altseason occurs when a broad range of alternative cryptocurrencies consistently outperform Bitcoin in price appreciation, often driven by increased speculation, innovation hype, or favorable macro conditions.
Q: Why only 9 altcoins? Can I customize the list?
A: Due to platform limitations on TradingView, only nine assets can be queried simultaneously. The current selection focuses on large-cap, high-liquidity altcoins for representativeness. Customization isn't supported in the standard script.
Q: Does a high index guarantee profits from altcoins?
A: No. The index indicates relative strength but doesn’t predict price direction. Even in altseasons, individual coins can underperform. Always conduct due diligence before investing.
Q: How often should I check the index?
A: Checking weekly is sufficient for most investors. Daily monitoring may benefit active traders looking to catch early shifts in momentum.
Q: Can this indicator be used for short-term trading signals?
A: It's best suited for medium- to long-term trend identification. For short-term entries/exits, combine it with oscillators or volume-based indicators.
Q: Is the script free to use?
A: Yes, the creator has released it as open-source under TradingView’s community guidelines. You can use it freely, but republication must comply with their house rules.
