Resistance

Resistance is a price level at which a stock or index tends to stall or reverse its upward movement because of concentrated selling pressure. It is one of the two foundational concepts in Technical Analysis, paired with Support. Resistance levels form where sellers historically become active — previous peaks, round numbers, or Fibonacci retracement levels.

The psychology behind resistance is straightforward. Investors who bought at higher prices and are sitting on losses often sell when the price returns to their entry level, happy to "break even." Additionally, traders who rode the rally may take profits at obvious price points. This collective selling creates a ceiling that the price struggles to penetrate.

Identifying resistance on Indian stocks involves studying price charts on daily, weekly, and monthly timeframes. For example, if Infosys peaked at INR 1,800 twice in the past year and pulled back each time, INR 1,800 becomes a recognised resistance level. The more times a level is tested without breaking, the stronger the resistance — but when it finally breaks, the move can be powerful as trapped sellers capitulate.

When resistance is decisively broken (a breakout confirmed by strong Trading Volume), that level often flips to become support — a phenomenon called "polarity." Traders look for this role reversal as a high-probability entry point. A breakout above resistance on heavy volume, followed by a successful retest of that level as new support, is considered one of the most reliable bullish chart patterns.

In Indian markets, key Nifty 50 resistance levels are widely discussed by analysts and on financial news channels. Round numbers (20,000; 22,000; 25,000) carry psychological significance and often act as resistance. Understanding resistance helps traders set realistic profit targets and identify potential reversal zones for their positions.
