Nifty RoadmapNifty 50 IndexNSE:NIFTYtradingwickThe Nifty 50 weekly chart shows a clear five-wave impulsive structure starting from the COVID low around March 2020 near 7,500. From this bottom, the index formed Wave 1 up to around October 2021, followed by a corrective Wave 2 that ended around June 2022. After that, the market began a strong extended Wave 3 rally from June 2022 to the all-time high region around September 2024 near 26,200–26,300. This Wave 3 was the strongest and longest wave, which is typical in Elliott Wave theory. After the completion of Wave 3, the market started a corrective phase which we are currently in, and this is being counted as Wave 4 on the weekly timeframe. Wave 4 is unfolding as an A-B-C corrective structure. Wave A declined from the all-time high to the first major support zone, Wave B formed a pullback rally that retraced a portion of Wave A, and now Wave C is in progress, which is the final leg of the correction. Using Fibonacci retracement on Wave 3, the key support levels for Wave 4 come around 23,500 (38.2%), 22,600 (50%), and 21,850 (61.8%). This is why the zone between 22,600 and 21,800 is a very important support region where Wave 4 can potentially complete. If the market stabilizes in this zone and momentum indicators like RSI start rising from below 50, it would indicate the completion of Wave 4 and the start of Wave 5 upward. However, the level 19,108 should not be treated as a normal Wave 4 retracement level. Instead, 19,108 represents the 38.2% Fibonacci retracement of the entire bull run from the COVID low (7,500) to the all-time high (26,200). This makes 19,108 a macro-degree Fibonacci support level. If the market falls to this level, then the current correction may not be just Wave 4, but a larger degree Wave (2) correction. In Elliott Wave theory, Wave (2) commonly retraces 38.2% to 50% of Wave (1), which places the major support between 19,100 and 16,900. Therefore, there are two main scenarios going forward. In the first scenario, the market holds the 22,600–21,800 zone, completes Wave 4, and then starts Wave 5, which can take the index toward 27,500, 30,000, or even higher based on Fibonacci extensions. In the second scenario, the market breaks below 21,800 with strong downside momentum and RSI moving toward 40, which can lead to a deeper correction toward 19,108. If 19,108 is reached, then the entire move from 2020 to 2024 will be considered Wave (1), the decline to 19,108 will be Wave (2), and then a very large Wave (3) rally can begin that may take the market toward 32,000–38,000 over the longer term. Time cycle analysis on the weekly chart also suggests that the correction window is approaching its maturity around March to April 2026, which aligns with the expected completion timing for either Wave 4 or the larger Wave (2). Momentum behavior is also important: if weekly RSI remains below 50, the probability of a deeper correction toward 19,108 increases; if RSI reclaims 50 and price moves above 24,600, then the Wave 4 bottom is likely already in place. In conclusion, the market is currently in a corrective phase, and the key decision zone lies between 22,600 and 21,800. Holding this zone will likely lead to Wave 5 up toward 30,000, while breaking this zone increases the probability of a deeper correction toward 19,108, which is the 38.2% retracement of the entire post-COVID bull run and a very significant macro support level.
