Volume Spikes Pro - relative volume comparison

The Enhanced Volume Spike Detector builds on the basic relative volume comparison by adding price direction analysis and more sophisticated categorization of volume events.

Directional Analysis
This indicator doesn't just identify volume spikes, but categorizes them as:
- **Bullish**: Volume spike with upward price movement
- **Bearish**: Volume spike with downward price movement
- **Neutral**: Volume spike with minimal price change
- **Strong**: Exceptional volume spike (2.5x+ default) regardless of direction

Visual Classification
Different color schemes instantly communicate the volume spike type:
- Green for bullish volume (price rising)
- Red for bearish volume (price falling)
- Dark Green for strong bullish volume
- Dark Red for strong bearish volume (price falling)

Customization Tips
