What are the maintenance changes for a demat account? Are there any hidden charges or processing fees on the transactions I do on demat account?

Maintenance charges are also known as folio maintenance charges, and is generally levied in advance. The transaction fee is charged for crediting/debiting securities to and from the account on a monthly basis. While some DPs, such as SBI, charge a flat fee per transaction, Some DPs charge only for debiting the securities while others charge for both. Answered by Shweta
