The Cosmic Trade platform appears to be relatively unknown or may not be one of the mainstream trading apps widely recognized in the market. Because of this, specific details about a referral code named “NDUMTM” or the exact terms of a 10% trading fee discount are difficult to confirm definitively.

Here is a general guide on how to apply a referral code on most trading platforms:

1. Download the App: Ensure you are downloading the official Cosmic Trade app from the Google Play Store or Apple App Store.
2. Register an Account: Open the app and start the sign-up process using your mobile number or email address.
3. Locate the Referral Field: Look for a box labeled “Referral Code,” “Invite Code,” or “Promo Code.” This is usually found on the first registration screen or a “Profile” section.
4. Enter the Code: Type NDUMTM into this field. Entering the code correctly before completing registration is usually essential to activate the discount.

If the code does not work, it may have expired or you might need to check if there is a minimum deposit or a specific first trade requirement to unlock the 10% fee discount. If the platform support options are available, checking directly within the Cosmic Trade app’s help section is generally the best way to confirm active promotions.
