I had an account with zerodha for past three years and really enjoying the flat brokerage by them. It’s max 20 rupee per trade or even lower than that.
They used the software of nse, so it’s very fast and timely. Just imagine a case when you buy equity of amount 1 Lakh and sell it on other day at 1.01 lakh that is with 1000/- profeet.
With other brokerage forms in India they will charge apprx 0.5% for buying of delivery and same for selling on delivery+ service tax+ other taxes, which will come around 1400/-. But with zerodha it’s least brokerage, Brokerage of buying and selling is 20+20+ tax which is less than 100.
They do not have any format of buying for intraday or delivery or anything as such, all are flat max 20/- per trade order or even lesser.
