LWMA: Linear Weighted Moving Average

The LWMA: Linear Weighted Moving Average indicator provides a customizable trend-following tool that applies linear weight distribution to price data to reduce lag and improve responsiveness to recent market movements.

Usage

The Usage section describes how the script can be used to identify market trends and potential reversal points. Because the LWMA places a higher mathematical priority on recent price action, it reacts faster than a Simple Moving Average (SMA) or Exponential Moving Average (EMA).

• Trend Identification: Users can observe the slope and color of the LWMA to determine the current trend direction. A rising, green line indicates bullish momentum, while a falling, red line indicates bearish momentum.
• Crossovers: Price crossing above the LWMA can be interpreted as a bullish signal, while crossing below may indicate a bearish shift.
• Support and Resistance: The moving average line often acts as a dynamic level where price may find support during uptrends or resistance during downtrends.
• Filtering: To account for potential false signals in low-volatility environments, it is recommended to use this tool alongside volatility oscillators or other volume-based filters.

Details

The script implements a specific linear weighting formula to ensure that the most recent data points have the greatest impact on the average. The calculation follows this logic:

LWMA = ((Pn * W1) + (Pn-1 * W2) + (Pn-2 * W3)...) / ∑W

Where:

• Pn represents the price for the current period.
• W represents the assigned weight, which descends linearly based on the lookback period and weight settings.

By adjusting the "LWMA Weight" parameter, users can control the steepness of the weighting gradient, allowing for a more aggressive or smoother reaction to price changes compared to standard WMA implementations.

Settings

• LWMA Source: Determines the price data used for the calculation (e.g., Close, Open, High, Low).
• LWMA Lookback Period: Sets the number of bars used to calculate the average.
• LWMA Weight: Controls the linear weighting factor applied to the calculation, affecting how heavily recent data is prioritized.
• Directional color change?: A toggle to enable or disable the visual color shift of the line based on whether the average is rising or falling.

FAQ

How does LWMA differ from a standard WMA? The LWMA uses a specific linear decay for weights that ensures a consistent reduction in priority for older data points, often resulting in less lag than standard weighted moving averages found in default library sets.

Can I use this for automated alerts? Yes, the script includes optimized alerts for trend direction changes (Rising/Falling) and price crossovers (Price crossing over/under the LWMA).
