Liquidation Levels

เมื่อวาน

## 🎯 What It Does

**Detects major liquidation events with abnormal volume and signals potential reversal opportunities at key liquidity levels.**

---

## ✨ KEY FEATURES

### Liquidity Level Detection
- **Major Liquidations Only** - Filters for significant events (40%+ importance)
- **Abnormal Volume** - Z-score analysis identifies unusual volume spikes
- **Heatmap Colors** - Lines color-coded by importance (Blue → Yellow → Orange → Red)
- **Auto-Cleanup** - Lines disappear when price moves through liquidity levels

### Reversal Signals
- **Tiny Flags** - Bright green (bullish) / Bright red (bearish) signals
- **Divergence Filter** - Optional RSI/MACD divergence confirmation
- **Quality Control** - Requires multiple confirmation factors
- **Smart Cooldown** - Prevents signal spam

---

## 🎨 VISUAL SYSTEM

**Horizontal Dotted Lines:**
- **Thickness** = Importance (thicker = more significant)
- **Color** = Heatmap gradient (Blue = minor, Red = critical)
- **Position** = Where liquidation occurred (high = long liquidation, low = short liquidation)

**Signal Flags:**
- **Green Flag** = Bullish reversal (short liquidation cleared)
- **Red Flag** = Bearish reversal (long liquidation cleared)
- **Size** = Tiny (minimal chart clutter)

---

## ⚙️ QUICK SETUP

**Default Settings (Balanced):**
- Min Importance: 40%
- Min Signal Strength: 2
- Signal Cooldown: 6 bars
- Divergence: Enabled
- Reversal Required: Enabled

**More Signals:**
- Lower Min Importance to 30-35%
- Lower Min Signal Strength to 1

**Fewer Signals (Higher Quality):**
- Raise Min Importance to 50-60%
- Raise Min Signal Strength to 3-4

---

## 💡 HOW IT WORKS

1. **Detects** major liquidations with abnormal volume
2. **Calculates** importance score (0-100%) based on:
- Volume abnormality (0-40 pts)
- Liquidation size (0-30 pts)
- Price range (0-20 pts)
- Wick rejection (0-10 pts)
3. **Signals** when liquidation + reversal + divergence align
4. **Removes** lines when price clears the liquidity level

## 🔔 ALERTS

- Bullish Liquidation Reversal
- Bearish Liquidation Reversal
- Major Liquidation Event

---

## ⚠️ NOTES

- **Works on all timeframes** - Auto-adjusts filters for lower timeframes
- **Lines auto-clean** - Disappear when price moves 0.5 ATR through level
- **Heatmap optional** - Can disable for simple gradient colors
- **Max 10 lines** - Keeps chart clean (adjustable)
- **Merges nearby lines** - Reduces visual clutter

**Liquidity Levels - Catch major liquidity grabs and trade the reversal.**

## 🔧 Recent Fixes & Improvements

### Memory & Performance Fixes
- **Fixed Array Size Limits** - Added strict limits to prevent "Array too large" errors
- Source array processing limited to 1,000 most recent items
- Filtered arrays limited to 500 items maximum
- Sorting operations limited to 200 items
- **Optimized Array Management** - Removed persistent arrays that could accumulate across bars
- **Improved Cleanup Logic** - More efficient filtering and merging of nearby lines

### Signal Quality Improvements
- **Balanced Signal Settings** - Adjusted defaults for optimal signal frequency
- Min Importance: 40% (major liquidations only)
- Min Signal Strength: 2 (requires confirmation)
- Signal Cooldown: 6 bars (prevents spam)
- **Smart Exception Rule** - Very abnormal volume events can trigger signals with lower importance threshold
- **Tiny Flags** - Signals displayed as smallest possible flags to reduce chart clutter

### Visual Enhancements
- **Heatmap Color System** - Lines color-coded by importance (Blue → Yellow → Orange → Red)
- **Auto-Cleanup** - Lines automatically disappear when price moves 0.5 ATR through the level
- **Line Thickness** - Scales with importance (thicker = more significant)
- **Merged Nearby Lines** - Combines lines within 0.5% to reduce visual clutter

### Cleanup Features (Lower Timeframes)
- **Auto-Cleanup for Lower TFs** - Automatically stricter filters on timeframes ≤15 minutes
- **Max Lines Display** - Default 10 lines (adjustable)
- **Min Importance Filter** - Default 30% (adjustable)
- **Nearby Line Merging** - Enabled by default to reduce clutter

### Technical Improvements
- **Bar Index Limits** - Lines only drawn from bars within 500 bar lookback (Pine Script limit)
- **Safe Array Operations** - All array operations include size checks and limits
- **Error Prevention** - Multiple safeguards prevent memory issues

## 💡 Usage Tips

**For More Signals:**
- Lower Min Importance to 30-35%
- Lower Min Signal Strength to 1

**For Fewer, Higher Quality Signals:**
- Raise Min Importance to 50-60%
- Raise Min Signal Strength to 3-4

**For Lower Timeframes:**
- Auto-cleanup is enabled by default
- Adjust Max Lines to 5-7 for very low TFs
- Increase Min Importance to 40-50% for cleaner charts
