On the Zerodha trading platform, the phrase "sold holding CNC" means that you have successfully executed a sell order for shares that were previously held in your delivery-based long-term portfolio (Cash and Carry). When you trade under the CNC product code, you are selling shares that you physically own in your demat account rather than squaring off an intraday margin position. The proceeds from this sale will be credited to your trading account balance according to standard stock exchange settlement cycles.
