What is Key-PA-Levels?

Key-PA-Levels draws configured 00, 20, 50, and 80 levels using a selected base timeframe. The Inputs image provides independent visibility switches and colors for the two level pairs.
These lines are a price-grid display. They can make repeated price areas easier to inspect, but a visible level does not determine whether price will stop or pass through.
How to use Key-PA-Levels

Select the base timeframe, then keep only the two level groups useful for the chart under review. Compare their placement with visible swings and candles.
The two Show inputs control the 00/50 and 20/80 groups, while each level color can be changed independently.
Where it helps
H sets the timeframe used for the level calculation.
00/50 and 20/80 groups have separate display switches.
Each of the four level types has its own color input.
