I am stock trader by profession, dealing in stock and derivatives. Initially I had 4 trading accounts with ICICI Direct, Motilal, Religare and Sharekhan. But since all of them are high on brokerage %. I was searching for a cheaper option and fortunately found ZERODHA.
Its charges amazing flat 20/- per executed order. That means no matter quantity you buy you need to pay just 20/-+ taxes =25 appx
It makes a lot of difference when you buy stock like SBI @ 1500/- per share if you buy 100 shares of Rs 150000/- then also your brkg will not exceed 25/--30/-
