Anju,
look at rpl as a derivative of mcx crude futures and ever since crude broke the double top neckline at around 5800 its was heading towards 5600,5200,4800,4500 and finally 4000....now its near 4800 and i would assume more damage . As far as your rpl options is concerned , Pls keep 159 cash level as stop for options as 178.3 is still a possibility given that 18 more days are left for expiry...
