Arent the commissions very pocket friendly on IBKR?I do have Interactive Brokers from last 5 years. They are good but they charge you for both buy and sell. IndMoney covers only India and US markets but Interactive Brokers cover almost all major markets across geographies be it Australia, EU, APAC, Africa and much more. Also you can buy MF, Bonds, Cryptos and many more financial instruments via IB. IndMoney is very limited w.r.t what can you buy
Also what bank are you using for remittances? I have hdfc imperia but they are not giving a great rate.
