The last-hour gains helped the Nifty 50 extend its upward trend for the third straight session on April 16, closing 0.5 percent higher ahead of the weekly F&O expiry on April 17. The index surpassed the 200-day EMA and the 78.6% Fibonacci retracement level (from the March high to the April low), with a positive bias in momentum indicators and oscillators, signaling further upside potential. According to experts, if the index sustains above the 200-day EMA (23,360), the next target zone would be 23,550–23,650. Above this, the 23,900 level will be the one to watch. In case of consolidation, on the downside, 23,200 is likely to act as a key support level, aligning with the upper band of the bullish gap formed on April 15.
