In a downtrend, price keeps making lower highs and lower lows, so the most recent peak where selling started is called the swing high. When price finally breaks above that swing high, it signals sellers are losing control and buyers are gaining strength, often becoming the first sign of trend reversal or bullish momentum. In this chart, the ₹21.50 zone is important because it acts as the latest swing high/resistance area where previous rallies were rejected. If price closes decisively above ₹21.50 with strong volume, it would invalidate the lower-high structure of the downtrend and can trigger fresh buying, short covering, and momentum toward higher resistance zones like ₹22.50–₹24.00.
