Fear Index: the dial between market panic and euphoria

Is the market scared or euphoric? The answer in 1 number.

Strategy Arena's AI Fear Index condenses all the arena's intelligence into a single score: 0 (extreme fear) to 100 (extreme euphoria).

Unlike the classic Crypto Fear & Greed Index (based on social media and volume), our index is calculated by 5 artificial intelligence systems that analyze real trading data.

The 5 components

1. Market regime (baseline)

The regime detector analyzes moving averages and momentum to classify the market: - BEAR → baseline 20 (fear) - VOLATILE → baseline 30 - NEUTRAL → baseline 50 - BULL → baseline 70 (confidence)

This is the same logic Ray Dalio applies with his economic cycles.

2. Invictus — Death rate

Invictus has absorbed 5,000 death contexts with 16 features each. Its death rate measures: under current conditions, what percentage of trades die?

  • Death rate > 60% → -15 points (danger)
  • Death rate < 40% → +15 points (safe zone)

Momentum and RSI are the two features that kill the most trades.

3. Chimera Scanner — Active pattern

The Chimera Scanner detects the pattern among its 1,221 patterns (51 million occurrences):

  • Fear patterns (TREMOR, THUNDER_DROP, DARK_MIRROR) → -10 points
  • Confidence patterns (PULSE_WAVE, BLITZ_RALLY) → +10 points
  • Neutral patterns (STEEL_WALL, SERPENT_COIL) → 0 points

4. Leviathan — Super-general's vote

The 7-layer super-general (contrarian 69%, regime 67.8%) gives its verdict: - SELL → -5 points - BUY → +5 points - HOLD → 0

5. Volatility

Instantaneous volatility measures the amplitude of recent movements: - Vol > 3% → -5 points (jittery market = danger) - Vol < 1% → +5 points (calm market = confidence)

The 5 zones

Score Zone Color Meaning
0-20 EXTREME FEAR Red Very dangerous conditions. Most trades die.
20-40 FEAR Orange Caution recommended. Defensive strategies outperform.
40-60 NEUTRAL Yellow Neither fear nor euphoria. Mean reversion strategies are favored.
60-80 GREED Light green Confidence. Momentum strategies perform well.
80-100 EXTREME GREED Green Euphoria — watch for reversals. Taleb's Barbell protects.
