Price Change — real-time visualization of market volatility and price movement intensity

To open the Price Change widget, select Widgets → Price Change.

The Price Change widget is an innovative tool for analyzing volatility and price changes of an instrument in real time. It visualizes the intensity of price movements on a scale from -100 to +100, where values above the threshold level indicate increased market activity.

Sliding Window Principle

The widget uses a two-period normalization system to adaptively display market changes.

How It Works

Two key parameters are used:

Measurement Window — the period used to calculate the current value.
Normalization Window — the period used to determine the display scale.

Algorithm:

Calculate the current change: Every second, the system calculates the price change over the selected measurement window.
Determine the maximum: The system analyzes all changes within the normalization window and identifies the largest deviation.
Normalize the visualization: The current value is displayed relative to the detected maximum.

Example:
Maximum change over 10 minutes = 5%
Current change = 1%
Widget indication = 20% (1% ÷ 5% × 100%).

Advantage

The widget automatically adapts its display scale to current market volatility, ensuring clear and intuitive visualization under any trading conditions.
