Laguerre RSI: An Advanced Oscillator for Market Analysis

The Laguerre RSI is an advanced oscillator based on digital filters, developed by John Ehlers. This indicator smooths price fluctuations using a technique called the Laguerre filter, allowing for more precise detection of overbought and oversold zones while reducing market noise.

The Laguerre RSI oscillates between 0 and 1, with standard levels set as follows:

• Overbought: above 0.75
• Oversold: below 0.25

This indicator is ideal for detecting market turns, precise entries, and signal confirmations.

Optional Features

The Laguerre RSI includes optional functionalities such as:

• Sound, email, or push alerts
• Visual filling between critical zones
• Flexible smoothing parameter (gamma)

User Manual

Configurable Parameters:

1. Main Configuration

• gamma (0.1 to 0.9):
  • Controls the degree of smoothing.
  • Lower values → more sensitivity, more signals.
  • Higher values → greater smoothness, less noise.
• overbought / oversold:
  • Levels for marking extreme zones.
  • Default:
    • overbought = 0.75
    • oversold = 0.25

2. Visual Appearance

• mainLineColor: Color of the main Laguerre RSI line.
• lineWidth: Thickness of the line.
• overboughtColor / oversoldColor: Colors of guide lines for key levels.
• fillBackground: Activates or deactivates filling between levels.
• fillColor: Color of the background zone (neutral).

3. Alerts

• alertsEnabled: Activates sound alerts when entering critical zones.
• emailAlerts / pushAlerts: Sends alerts via email or mobile notifications.
• alertPrefix: Custom text at the beginning of the alert message.

Suggested Strategies

 Strategy 1: Confluence with MACD (D1 + H1)

Objective: To trade only in favor of the larger trend, using the Laguerre RSI as a trigger on lower timeframes.

Step-by-step:

1. Open the chart in the daily timeframe (D1).
2. Apply the standard MACD (12, 26, 9).
   • If the MACD is below 0 → only look for SELLS.
   • If the MACD is above 0 → only look for BUYS.
3. Switch to the H1 timeframe.
4. Apply the Laguerre RSI.

 Combined Strategy with MACD and Laguerre RSI

When the MACD on the daily timeframe (D1) is below 0, the overall trend is bearish.

•  In that case, switch to H1 and wait for the Laguerre RSI to cross downwards from the 0.75 level. This indicates a selling opportunity.

When the MACD on D1 is above 0, the trend is bullish.

•  Then, switch to H1 and wait for the Laguerre RSI to cross upwards from the 0.25 level. This signals a good buying opportunity.

 Advantages:

• Superior trend filter + entry precision.
• Reduces false signals.
• Increases success probability.

 Strategy 2: Extreme Reversals

Wait for the Laguerre RSI to reach extremes (≈ 0 or ≈ 1) and then return to the middle range (0.5) to consider a reversal.

 Strategy 3: With Support/Resistance

Combine the Laguerre RSI with key horizontal price levels. Enter when the price touches support/resistance and the RSI is in the opposite zone (buy at support + RSI < 0.25).

Final Recommendation

Use the Laguerre RSI as a complement to your analysis, not as a sole signal. It can be especially powerful when combined with:

• MACD
• Market structure
• Price action
