MUMBAI : The stock market regulator is planning to scrap an old rule preventing brokers from operating trading terminals from locations other than those reported to the exchange, two people aware of the matter said, raising the possibility of many brokers working from home over the longer term.The change comes after compliance relaxations given to brokers during the coronavirus lockdown allowed them to operate terminals from home or other remote locations.These relaxations given by the Securities and Exchange Board of India (Sebi) worked without a glitch and are likely to continue till at least June end, the people cited above said on condition of anonymity.
