### What AlgoPro Support & Resistance Does

AlgoPro Support & Resistance is an overlay tool that plots support/resistance zones, volume order blocks, and trendline-style structure.

### Main Systems

It includes:

* Support & Resistance zones
* Swing High / Low Length
* Support & Resistance History
* Box Width
* Volume Order Blocks
* Order Block Sensitivity
* Bullish/Bearish OB colors
* Trendline systems
* Alerts from zone interactions

### Support & Resistance Inputs

#### Enable Support & Resistance

Turns the main zone system on or off.

#### Swing High / Low Length

Controls how pivots are detected.

Lower values create more zones.

Higher values create fewer but more important zones.

#### Support & Resistance History

Controls how many zones remain visible.

#### Box Width

Controls how thick the support/resistance zones are.

### Volume Order Blocks

The tool includes volume order blocks with:

* Enable Volume Order Blocks
* Order Block Sensitivity
* Bullish Order Block color
* Bearish Order Block color

### Alerts

The script uses alert calls when price interacts with supported levels/zones.

### Best Use

Use this tool to identify areas where price may react. It is not meant to be used as a blind entry system by itself.
