What is this indicator?
Unlike Fibonacci retracement, which shows pullback levels, this tool marks probable targets for the continuation of a move after a correction. It's usually used to set a take-profit target in the direction of the main trend.
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.
