LAGUERRE RSI Trading Guide
The Laguerre RSI, pioneered by John Ehlers, serves as a high-fidelity digital adaptation of the traditional RSI. By utilizing a four-pole Laguerre filter rather than simple exponential math, it achieves far superior smoothing while dramatically reducing the inherent lagging delay experienced by legacy oscillators.
What does the indicator show?
- RSI Line: A highly responsive oscillator line that rapidly snaps between extreme values (0 to +100) with minimal whiplash.
- Extreme Levels: Clean, static boundary lines drawn at the critical 20 and 80 thresholds.
Key Settings
- Gamma (Damping): The core multiplier dictating responsiveness. A lower gamma (e.g. 0.3) makes the curve extremely jumpy and aggressive, whereas a higher gamma (e.g. 0.8) heavily smooths the curve to mitigate noise.
- Source: Allows mapping calculations to alternate price points like High/Low averages instead of strict Closes.
How to use Strategy Parameters (Condition Source)
Using Laguerre RSI inside the Strategy Tester is ideal for short-term cyclical swing trading logic without suffering the delays of standard moving average logic.
1. Oscillator & Momentum Values
rsi— The precise calculation plotted smoothly between 0 and 100.direction— A straightforward tracker outputting `1` if the line is climbing upward, and `-1` if the line is falling over.
Strategy Example: To create a highly reactive dip-buying bot, generate a Long signal where rsi crosses above 20, ensuring you buy the exact moment selling exhaustion reverses into an uptrend.
