Liquidation Heatmap & Level Analysis

# Long position liquidation
long_liquidation_price = entry_price * (1 - 1/leverage + maintenance_margin)

# Short position liquidation
short_liquidation_price = entry_price * (1 + 1/leverage - maintenance_margin)

# Example: BTC long at $65,000, 10x leverage, 0.5% maintenance margin
# Liquidation: $65,000 * (1 - 1/10 + 0.005) = $58,825
# A 9.5% move against the position triggers liquidation

   ↓
2. Price hits first liquidation cluster ($65,000)
   → $200M in long liquidations forced to sell
   ↓
3. Forced selling pushes price to next cluster ($63,000)
   → $300M more in long liquidations
   ↓
4. Cascade accelerates → high-leverage positions ($62,000-$60,000)
   → $500M in rapid succession
   ↓
5. Eventually: open interest drops 20-30%, funding rate flips negative
   → Leverage is "washed out" → bottom forms
   ↓
6. Recovery begins (short-term) as no more forced sellers remain

## Liquidation Analysis — [Asset] — [Date]

### Liquidation Overview (24h)
- **Total liquidated**: $XXX M
- **Long liquidated**: $XXX M (XX%)
- **Short liquidated**: $XXX M (XX%)
- **Largest single**: $XX M [exchange]
- **Market state**: [extreme / elevated / normal / calm]

### Key Liquidation Levels
| Price Level | Type | Est. Volume | Distance from Current | Priority |
|------------|------|-------------|----------------------|----------|
| $XX,XXX | Short liq cluster | $XXX M | +X.X% | High |
| $XX,XXX | Long liq cluster | $XXX M | -X.X% | High |
| $XX,XXX | Long liq cluster | $XXX M | -X.X% | Medium |

### Heatmap Summary
- **Strongest upside magnet**: $XX,XXX (short liquidation cluster, $XXX M)
- **Strongest downside magnet**: $XX,XXX (long liquidation cluster, $XXX M)
- **Asymmetry**: [upside magnet stronger / downside stronger / balanced]

### Cascade Risk
- **Downside cascade risk**: [high / moderate / low]
  - [X clusters stacked within X% below current price]
- **Upside cascade risk**: [high / moderate / low]

### Post-Liquidation S/R Levels
- **Recent support formed**: $XX,XXX (long liquidation wipeout on DATE)
- **Recent resistance formed**: $XX,XXX (short liquidation wipeout on DATE)

### Trading Implications
- **Bias**: [upward magnet stronger → mild bullish / downward → bearish]
- **Risk**: [high leverage zone within X% → reduce position size]
- **Key level**: [$XX,XXX — if broken, cascade risk activates]
