@pratik01@pavz In 2014-15, NSE issued a circular to TMs (brokers) stating that their data could only be used from authorized sources and for internal purposes. As the term “internal purposes” was vague, some TMs started using the data to create stock market games, paper trading, and copy trading. Some also used this data, via the sub-broker route, to create “dabba” trading apps using the same data sources.
It is prohibited to create virtual trading apps using real-time data. However, for virtual trading, they use one-minute delayed data to comply with SEBI and NSE regulations.
