Overview
[RS] Simple Forecast - Keltner Worms calculates exponential moving averages and range-based band offsets, dynamically adjusting the channel multiplier to encompass price moves. The resulting channels are projected forward into future bars using positive plot offsets to visualize projected price boundaries. The primary setting allows users to change the input price source. It provides visual volatility channels rather than explicit buy or sell trade signals.
- Multiple Keltner Channel lookback periods
- Dynamic auto-multiplying channel bands
- Forward-projected plot offsets
- Customizable input source selection
