If you wish to use any of our integrated partner platform, wherein you can login with your Dhan account and trade, there are no additional charges from Dhan. You will only be charged brokerage as per the Pricing Policy.

However, such partner platforms might have platform subscription/usage charges associated. We do recommend checking that with the platform directly.
