Power Signal v6 Description

Power Signal Indicator (PSI) is a market strength indicator that combines volume analysis and price proximity to daily highs to generate high-quality trading signals.
What the Indicator Does

The script calculates a "Power Index" based on two key components:

Proximity to High — measures how close the current price is to the previous day's high in percentage terms

Relative Volume — compares current volume to the average volume over a selected period (default 20 bars)

When price is within 1% of the daily high AND volume exceeds 150% of average, the indicator applies a 1.2 multiplier to the relative volume, creating the "Power Index". When this index crosses a defined threshold (default 150), it generates a PSI! signal with a visual marker on the chart and an audio alert.
Visualization

Main line displays in a separate pane below the chart

Line color: lime (when Power > 100) or gray

Information table in top-right corner shows current values of all components
