Indicator: WaveTrend Oscillator

The WaveTrend Oscillator indicator identifies potential market reversals and trend exhaustion by tracking momentum cycles through a dual-line oscillator system.

Usage

The WaveTrend Oscillator is primarily used to identify overbought and oversold conditions in various financial markets. Traders typically look for the following signals:

• Bearish Reversal: When the oscillator (WT1) rises above the upper overbought bands (red lines) and subsequently crosses below the signal line (WT2).
• Bullish Reversal: When the oscillator (WT1) falls below the lower oversold bands (green lines) and subsequently crosses above the signal line (WT2).
• Momentum Strength: The shaded area representing the difference between WT1 and WT2 (WT Diff) helps traders visualize the velocity of the current price move.

Examples of usage include using the overbought/oversold levels to time exits on existing trends or using the crossovers as entry triggers in mean-reversion strategies.

Details

The WaveTrend Oscillator is a port of a classic technical analysis tool designed to improve upon traditional oscillators like the RSI or Stochastic. It calculates the relationship between price (HLC3) and its Exponential Moving Average (EMA) to create a "Channel Index."

1. Price Basis: It uses the typical price (HLC3), which is the average of the High, Low, and Close.
2. Smoothing: The script applies an EMA to the typical price to establish a baseline (ESA), then calculates the mean absolute deviation to normalize the oscillator values.
3. Signal Generation: The main oscillator (WT1) is a smoothed version of this normalized value, while the signal line (WT2) is a simple moving average of WT1. This creates a lag-sensitive crossover system that filters out minor price noise while capturing cyclical swings.

Settings

• Channel Length: Determines the period used for the initial EMA and deviation calculations. Smaller values make the indicator more sensitive to price changes.
• Average Length: Sets the smoothing period for the TCI calculation. Higher values result in a smoother, slower-moving oscillator.
• Over Bought Level 1: Defines the primary upper boundary for overbought conditions (default is 60).
• Over Bought Level 2: Defines a secondary, less extreme upper boundary for overbought conditions (default is 53).
• Over Sold Level 1: Defines the primary lower boundary for oversold conditions (default is -60).
• Over Sold Level 2: Defines a secondary, less extreme lower boundary for oversold conditions (default is -53).

FAQ

How do I interpret the red and green dotted lines? The red dotted lines represent overbought thresholds, suggesting price may be extended to the upside. The green dotted lines represent oversold thresholds, suggesting price may be extended to the downside.

What is the difference between WT1 and WT2? WT1 is the main oscillator line that tracks momentum, while WT2 is a signal line (a moving average of WT1). Crossovers between these two lines are often used to trigger entries and exits.
