MUMBAI: HDFC Protections, one of the main broking firms in India, on Monday sent off an application pointed toward assuming the huge number of rebate businesses that have caught an enormous piece of the pie in the stock broking space, essentially through minimal expense administration contributions. Throughout the course of recent years, tech-driven markdown specialists like Zerodha, Groww, Upstox and 5Paisa have onboarded countless dealers and financial backers, for the most part at the expense of the enormous, full-administration businesses.
