    Support and Resistance (S&R) are the most fundamental concepts in technical analysis. Every chart pattern, every indicator, every trading strategy ultimately relates back to these two price levels. Support is a price level where demand (buying) is strong enough to prevent further decline. Resistance is where supply (selling) caps upward movement. Think of support as a floor and resistance as a ceiling.

    Key points

    Support forms when buyers step in at a specific price level repeatedly. The more times a level is tested and holds, the stronger it becomes
    Resistance forms when sellers consistently reject price at a specific level. Multiple rejections make the resistance stronger
    Role Reversal: When a support level breaks, it often becomes resistance (and vice versa). This is one of the most reliable concepts in TA
    Round Number Psychology: ₹100, ₹500, ₹1000, ₹10,000, ₹20,000 often act as psychological S&R because humans think in round numbers
    Volume at S&R: High volume bounces off support = strong support. High volume breakdown below support = genuine breakdown
    Multiple Timeframe Confluence: A support level visible on daily, weekly, AND monthly charts is far more powerful than one visible only on a daily chart
    Dynamic Support/Resistance: Moving averages (20-DMA, 50-DMA, 200-DMA) act as dynamic (moving) support and resistance levels
    Gap Support/Resistance: Price gaps (unfilled open areas on charts) often act as strong S&R zones. Gap-fill is a common trading concept
    Demand/Supply Zones: Wider areas (not exact prices) where multiple S&R levels cluster. More practical than single price lines
    NIFTY Key Levels: Every Chartbook edition includes specific S&R levels for NIFTY, Bank NIFTY, and major stocks — updated weekly

    Example — NIFTY 50 has strong support at 24,000-24,100 (tested 3 times in March 2026, bounced each time with high volume). Resistance at 24,750-24,950 (rejected twice with upper wicks). A break above 24,950 on weekly closing would signal a fresh bullish breakout.

    Pro tip — Never draw just one line for support or resistance. Use ZONES — a range of 1-2% around the level. Markets are not precise; they test and probe levels. A stock with support at ₹500 might dip to ₹495 before bouncing. If your stop-loss is at exactly ₹500, you'll get stopped out before the reversal.
