EMA Study Script for Price Action Traders

This indicator creates an Exponential Moving Average (EMA) with customizable bands around it.

The bands can be based on three different calculation methods:
1. Full Average Bar Range (high-low)
2. Body Average Bar Range (open-close)
3. Standard Deviation of the EMA

Users can display up to three bands above and below the EMA, with options to customize the colors, transparency, and whether to fill the area between bands. The indicator serves both as a research tool for studying price action around EMAs and as a potential trading tool for identifying volatility zones.

Key features:
- Configurable EMA period and color
- Three different band calculation methods
- Up to 3 standard deviations of band display
- Optional band filling with customizable color and transparency
- Overlay display for easy price action analysis
