Rupak De, Senior Technical analyst at LKP Securities, said, "The bulls were able to protect the level of 19,600 during the day, thanks to the strong open interest (OI) build-up at the 19,600 strike price by put writers. The strength may continue as long as the index remains above 19,600. Only a decisive fall below 19,600 might trigger serious long unwinding in the market, till then a buy-on-dips strategy to favor the market. On the higher end, resistance is visible at 19,850; above this, the index might move towards 20,000."
