On the Zerodha trading platform (and across Indian stock exchanges like the NSE and BSE), EQ stands for Equity delivery trades. When investors buy shares under the "CNC" (Cash and Carry) or long-term delivery product type, they are transacting in the EQ segment. This indicates that the shares will be fully paid for and settled directly into the investor's Demat account for long-term holding, as opposed to intraday margin trades.
