Why have I been charged brokerage even though I have taken delivery trades in Equity?
You will be charged brokerage for delivery based trades only in scenarios where you have partially squared off your CNC position before the end of the trading day. Such trades are considered to be intraday transactions and brokerage at intraday rates is charged on the complete order value.
For example, let's say you have purchased 100 shares of TCS at Rs 1800 using the CNC product type but you sold 30 shares at 1810 before the market closes, you will be charged the intraday brokerage charges (0.03% or Rs 20 per executed order, whichever is lower). In this scenario, that would be Rs 20 [100*1800*0.03% or Rs. 20] + Rs 16.29 [30*1810*0.03% or Rs. 20] = Rs 36.29
