Everyone is saying that Nifty Lot size is changed to 75 from 25, but I still see it as 25 for any month/week in the future. All options are 25 lot. Any Comments? and if we have existing positions of 25 lot size in the future, how will zerodha change it to 75? eg. if we have 200 qty, how will Zerodha change it as per 75 lot size and when?
