If I am not wrong then Traded Value is basically VWAP*Traded Shares.
Not sure about your data source but NSE Bhavcopy suggest below numbers for 1st Nov in total of all stocks:
Quantity_Traded : 46,531,345
del_quantity_gross : 17,306,945
Delivery% could be lesser as most of the big players square of the position in the end and the active buy sell orders that are in the exchange queue get adjusted after market closure and arbitrage opportunity between BSE and NSE also gets adjusted based on price difference..so multiple reasons for the difference
