Nifty Trade setup for October 17

Bulls maintained their strong hold over the market for another session, lifting the Nifty 50 index 1 percent higher on October 16. The index achieved its highest closing level since June this year, supported by bullish technical and momentum indicators. Experts believe this may reflect a pre-Diwali celebration mood on the Street, which is expected to help the index reach this year's high of 25,669 soon, followed by 26,000, a crucial resistance level before the record high hurdle. However, the 25,400–25,300 range can act as a support zone.Image116102025

8) Put-Call Ratio

The Nifty Put-Call ratio (PCR), which indicates the mood of the market, jumped to 1.38 on October 16 (the highest level since September 23, 2024), compared to 1.21 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.
