What is this indicator?
A version of pivot points with a different formula that produces tighter support/resistance levels closer to price. It's used mostly in intraday trading to spot zones of quick price reversal.
How to read the chart
Price approaching these levels sets up probable reactions (support, resistance, or a breakout), and traders usually watch how price behaves in exactly these zones.
Practical tip
These levels aren't definitive — they're just probable reaction zones; getting confirmation from price action or volume before deciding is recommended.
