Trade setup for September 16: Top 15 things to know before the opening bells

16 Sep , 2025 By : Debdeep Gupta

The Nifty 50 snapped its eight-day winning streak on September 15, closing 0.2 percent lower after trading within the previous day’s range. This appears to be a pause amid caution ahead of the FOMC interest rate decision due on Wednesday. However, the overall trend remains favourable for bulls as long as the index holds the 25,000–24,800 support zone. Technical and momentum indicators are still supportive of the ongoing uptrend. On the higher side, 25,150 is expected to be the immediate key hurdle. A decisive break above this level could open the door for a healthy upward move, according to experts.

Here are 15 data points we have collated to help you spot profitable trades:

1) Key Levels For The Nifty 50 (25,069)

Resistance based on pivot points: 25,120, 25,141, and 25,175

Support based on pivot points: 25,051, 25,030, and 24,996

Special Formation: The Nifty 50 formed a bearish candle with minor upper and lower shadows on the daily chart, indicating a rangebound session after failing once again to retest the August high. The index sustained well above all key moving averages, with positive crossovers of the 10-day and 20-day EMAs over the 50-day EMA. The MACD maintained a strong bullish crossover, with further strength visible in the histogram. The RSI tilted downward but continued to hold its positive crossover, closing at 59.01. All of this indicates that the underlying momentum remains positive, and the uptrend is still intact.

2) Key Levels For The Bank Nifty (54,888)

Resistance based on pivot points: 54,985, 55,035, and 55,116

Resistance based on Fibonacci retracement: 55,132, 55,610

Support based on Fibonacci retracement: 54,418, 53,420

Special Formation: The Bank Nifty extended its upward trend for the ninth consecutive session, forming a Doji candlestick pattern on the daily timeframe. This suggests indecision among bulls and bears. Notably, the index climbed above the 100-day EMA for the first time since August 25, while also sustaining above the 10-day and 20-day EMAs. The RSI improved to 50.95, maintaining its bullish crossover. The MACD also showed a positive crossover, with continued strengthening of the histogram. All of this indicates improving momentum and trend strength in Bank Nifty.
