ATR Keltner Channels [iryna]

171
Hello!

I’m excited to share my custom ATR Keltner Channel script, built around a 21-period EMA and ATR-based volatility bands. I am using this tool myself for watching price behavior, any pullbacks or breakouts, and to visualize dynamic support and resistance.

How it works:
• The centerline is a 21-day Exponential Moving Average (EMA), giving you a smooth sense of the trend.
• The upper and lower bands are calculated using Average True Range (ATR), so they expand and contract based on volatility.
• The upper and lower bands are x1ATR, x2ATR, x3ATR.

All my knowledge comes from SpikeTrade community, where I am learning from Kerry Lovvorn and Alexander Elder.

Let me know if you have any suggestions to improve or update!

Have a fruitful trading session!
- Iryna
