Altcoin Season Index [Dynamic Eras] | CriptoMatiko
The Altcoin Season Index [Dynamic Eras] measures the percentage of top altcoins that have outperformed Bitcoin over a configurable rolling window (default: 90 days). Values above 75 indicate Altcoin Season; values below 25 indicate Bitcoin Season.

WHAT MAKES THIS VERSION DIFFERENT
─────────────────────────────────────────────
Most Altcoin Season Index implementations use a fixed basket of coins evaluated against a static lookback window. This version solves two problems with that approach:
**1. Dynamic Eras — basket that reflects each market cycle**
The top altcoins in 2020 are not the same as in 2024. Including dead projects (LUNA, FTT) or irrelevant coins in later periods creates misleading signals. This script uses 6 time-based baskets:
- Era 1 (before Oct 2020): 20 coins — pre-DeFi legacy basket
- Era 2 (Oct 2020 – Oct 2021): 25 coins — DeFi Summer + Bull Run
- Era 3 (Oct 2021 – Oct 2022): 25 coins — Cycle top + early bear
- Era 4 (Oct 2022 – Oct 2023): 25 coins — Bear Market survivors
- Era 5 (Oct 2023 – Oct 2024): 30 coins — Recovery + ETF + Halving
- Era 6 (Oct 2024+): 30 coins — AI & Meme narrative leaders
**2. Variable denominator**
The denominator changes with each era (20 / 25 / 30) to match the actual basket size, keeping the 0–100 scale consistent and meaningful across all historical periods.
Total tracked assets: 40 (BTC + 39 altcoins across 5 tiers: established majors, DeFi, L2s, AI, Meme).

TECHNICAL IMPLEMENTATION
─────────────────────────────────────────────
Performance for each asset is calculated WITHIN the daily context of request.security() — not on the chart's current timeframe. This ensures the 90-day rolling window always measures 90 calendar days, whether you are viewing a 1H or 1W chart. The calculation is: (close - close[win]) / close[win] * 100, evaluated daily.

HOW TO READ IT
─────────────────────────────────────────────
- Above 75 → Altcoin Season: more than 75% of the active basket outperformed BTC in the last 90 days
- Below 25 → Bitcoin Season: Bitcoin dominates; most altcoins underperform
- 25–75 → Neutral: mixed conditions, no clear rotation signal

INPUTS
─────────────────────────────────────────────
Model Settings:
- Comparison Window (days): rolling lookback period (default 90)
Regime Thresholds:
- Altcoin Season Threshold: upper boundary (default 75)
- Bitcoin Season Threshold: lower boundary (default 25)
Visual:
- Show Background Zones: highlights Altcoin Season and Bitcoin Season zones
- Show Status Table: toggles the bottom-right info panel
─────────────────────────────────────────────
STATUS TABLE
─────────────────────────────────────────────
- Index: current index value (0–100)
- Regime: ALTCOIN SEASON / NEUTRAL / BITCOIN SEASON
- Era / Basket: current era number and active coin count
- Data: LIVE when price feeds are connected, WAITING otherwise

CHART ANNOTATIONS
─────────────────────────────────────────────
The circles on the lower pane mark historical extreme readings — index peaks above 75 (Altcoin Season) and troughs below 25 (Bitcoin Season). The arrows on the price chart illustrate the directional moves that followed those extremes, showing the historical correlation between extreme index readings and subsequent price reversals.
