Bank nifty has fallen more than 3 percent last Friday and it is closer to 200 day simple moving average that is 35500 to 35700 zone... Please note it's not a line it is a zone. Any stock or index should respect it technically atleast a pull back for a day or two. So it's better to buy long options like Dec monthly or Jan series far OTM options and exit with reasonable profits... I'm taking Jan series 40000 CE below 200 for a target of 300...its not a recommendation just my view for educational purposes
