Nifty opened the week on a firm note, closing the previous session at 25,507.45, marking a marginal gain. On the 4H timeframe, price is now touching the upper Bollinger Band—indicating that the index is trading at the higher end of its volatility envelope. Historically, such moves often lead to brief pauses or shallow pullbacks unless volume expansion supports further rally. The RSI (14) stands at 65.06, showing strength but also hinting that the index is nearing overbought territory. Momentum remains firmly with the bulls, as the RSI continues its higher-high structure along with price. The Bollinger Band width is gradually expanding, suggesting increasing volatility and a potential trend continuation. Key Levels to Watch: Immediate support: 25,138 (middle Bollinger Band) & 24,900 Resistance zone: 25,730–25,800 (upper BB & psychological hurdle) Bias: Buy-on-dips remains favorable as long as Nifty holds above 25,100 Disclaimer: This analysis is for educational purposes only and is shared by Mayank Gupta, SEBI-Registered Research Analyst (INH000015978).
