Price Volume Trendline

前天

The Price Volume Trendline indicator calculates and displays a linear regression trendline based on the product of volume and price (e.g., Volume * Close, Volume * Open, etc.) for a specified timeframe. The indicator helps visualize the relationship between price and volume movements over time.

Note - Please choose a timeframe to display the trendline.

Key Features:

Linear Regression: The trendline is computed using a linear regression of Volume * Price values over a user-defined length (length_trend), providing a smoothed representation of the trend.

Color Coding: The trendline color changes dynamically:
Green: When the slope of the trendline is positive (indicating an uptrend in Volume * Price).
Red: When the slope of the trendline is negative (indicating a downtrend in Volume * Price).
Customizable Timeframe: Users can choose the timeframe for the Volume * Price calculation (either "auto" for the chart's timeframe or a custom timeframe).

This indicator is useful for identifying long-term trends in the relationship between price and volume, highlighting bullish or bearish conditions based on both price and volume dynamics.
