I am seeing at the end of Zerodha contract note mention about the trading member. Who is that trading member? Is he associated with the stock broker?
There are different types of registrations a broker can have on an exchange, Zerodha has a trading member licence on the exchanges. A trading member allows clients of his to trade on an exchange.
