Trade setup for August 13: Top 15 things to know before the opening bells

13 Aug , 2025 By : Debdeep Gupta

The Nifty 50 reversed some of its previous day's gains and finished the session 98 points lower on August 12. The index failed to defend the 100-day EMA and lost more than 200 points from the day's high of 24,700, which is expected to be the immediate hurdle, followed by 24,850 (near the 50-day EMA) as the crucial hurdle to decide the further uptrend. Until these levels are decisively broken and sustained, the consolidation may continue, with key support at 24,300 — below which the bears may come into strong action, according to experts.

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

1) Key Levels For The Nifty 50 (24,487)

Resistance based on pivot points: 24,642, 24,698, and 24,789

Support based on pivot points: 24,461, 24,405, and 24,315

Special Formation: The Nifty 50 formed a bearish candle with a long upper shadow on the daily timeframe, indicating selling pressure at higher levels. The index still sustained below the short-term (10- and 20-day EMA), medium-term (50-day EMA), and long-term moving average (100-day EMA), which is a negative sign. The momentum indicator RSI dropped below the 40 mark, to 39.56, and the MACD remained below the zero line, though the Stochastic RSI maintained a positive crossover in the lower band. This indicates weakness in the market and a lack of strong buying interest at higher levels.

2) Key Levels For The Bank Nifty (55,044)

Resistance based on pivot points: 55,420, 55,553, and 55,769

Support based on pivot points: 54,988, 54,855, and 54,639

Resistance based on Fibonacci retracement: 55,947, 56,271

Support based on Fibonacci retracement: 54,405, 53,403

Special Formation: The Bank Nifty also saw a bearish candle formation, losing 467 points after a day of rally. The index remained below the short-term and medium-term moving averages, though it has been holding the 100-day EMA for the fourth consecutive session, signalling immediate support. The MACD stayed below the zero line, and the RSI fell below the 40 zone to 37.14, while the Stochastic RSI maintained a positive crossover but remained in the oversold zone. This indicates that while there may be some support, the overall sentiment remains weak.

3) Nifty Call Options Data

According to the weekly options data, the 25,000 strike holds the maximum Call open interest (with 1.57 crore contracts). This level can act as a key resistance for the Nifty in the short term. It was followed by the 24,700 strike (1.22 crore contracts), and the 24,600 strike (1.18 crore contracts).

Maximum Call writing was observed at the 24,700 strike, which saw an addition of 61.56 lakh contracts, followed by the 25,000 and 25,200 strikes, which added 47.93 lakh and 40.77 contracts, respectively.

4) Nifty Put Options Data

On the Put side, the maximum Put open interest was observed at the 24,000 strike (with 92.8 lakh contracts), which can act as a key support level for the Nifty. It was followed by the 24,400 strike (81.25 lakh contracts) and the 24,500 strike (80.62 lakh contracts).

The maximum Put writing was placed at the 24,700 strike, which saw an addition of 8.5 lakh contracts, followed by the 23,800 and 23,850 strikes, which added 7.07 lakh and 4.91 lakh contracts, respectively.

5) Bank Nifty Call Options Data

According to the monthly options data, the maximum Call open interest was seen at the 57,000 strike, with 23.81 lakh contracts. This can act as a key resistance level for the index in the short term. It was followed by the 56,000 strike (14.77 lakh contracts) and the 55,500 strike (12.12 lakh contracts).

Maximum Call writing was observed at the 55,500 strike (with the addition of 2.49 lakh contracts), followed by the 56,000 strike (1.73 lakh contracts), and the 55,000 strike (1.72 lakh contracts). There was hardly any Call unwinding seen in the 53,250-57,250 strike band.

8) Put-Call Ratio

The Nifty Put-Call ratio (PCR), which indicates the mood of the market, fell to 0.78 on August 12, compared to 1.03 in the previous session.

The increasing PCR, or being higher than 0.7 or surpassing 1, means traders are selling more Put options than Call options, which generally indicates the firming up of a bullish sentiment in the market. If the ratio falls below 0.7 or moves towards 0.5, then it indicates selling in Calls is higher than selling in Puts, reflecting a bearish mood in the market.

9) India VIX

India VIX, which measures expected market volatility, inched up further, rising 0.12 percent to 12.23. It remained above the short-term moving averages with a positive crossover in the 10-day and 20-day EMA, signalling some caution for bulls.

10) Long Build-up (36 Stocks)

A long build-up was seen in 36 stocks. An increase in open interest (OI) and price indicates a build-up of long positions.

11) Long Unwinding (39 Stocks)

39 stocks saw a decline in open interest (OI) along with a fall in price, indicating long unwinding.

12) Short Build-up (102 Stocks)
