3. Zigzag Indicator for Support and Resistance: The Zigzag indicator helps in identifying significant highs and lows in the price movement. You can use these levels as potential stop-loss and take-profit points. For instance, set stop-loss just below the recent swing low for long positions and take-profit at the nearest swing high.
