Quick update:. USDINR's option chain is no more suitable for monthly or weekly call, put buyers. I have been trading USDINR since august and I noticed that after introducing weekly expiry on 3rd december USDINR's option premimum are eating much faster than before and also THETA, GAMA, VEGA is so challanging because it working so quikcly up and down following price action you can't even book partial profit..... I assumed that Rupee wherever heading towards on every opportunuty selling call and put option is the core beneifcial. otherwise you're gonna lose all money you have rather making a thang
