Why are DP charges not shown in the contract note?
DP charge or Depository Participant charge is levied on stock movement out of the DEMAT account which is managed by depositories (NSDL or CDSL).
The contract note captures all trading and its related charges, executed on the stock exchanges (NSE or BSE).
Since DP charges and contract note charges are dissociated, DP charges are levied separately on the ledger and not on the contract note.
On the same ground, Demat Account Maintenance Charge is also levied separately on the ledger. Please click here to have a look at the list of charges while trading with Zerodha.
