Why am I encountering the 'NOT allowed to trade in BSE MF' error on FYERS?
Running into the “NOT allowed to trade in BSE MF” error while trying to place a mutual fund order on FYERS can be frustrating. This message usually indicates a temporary issue related to account configuration or segment availability. Here's what it means and how to resolve it.
What does this error mean?
This error appears when your account is not currently authorized to place trades in the BSE Mutual Fund (MF) segment. FYERS processes mutual fund orders through the BSE Star MF platform, and certain system or exchange-side validations must pass for your order to go through.
Common reasons for the error
1. UCC mapping delay
- UCC stands for 'Unique Client Code'.
- After onboarding, your UCC must be successfully mapped on BSE’s side.
- If there's a delay in this backend mapping, you may encounter this error.
2. BSE MF segment inactive
- Sometimes the BSE MF segment is temporarily inactive or under maintenance.
- When inactive, it blocks order placement across all participating platforms, including FYERS.
What if?
| Scenario | Explanation |
|---|
| You’re a new investor facing this error | Your UCC mapping may still be in process—wait a few hours or contact support. |
| You were able to trade earlier, now see this error | This may be due to temporary BSE segment downtime—try again later. |
| Error persists after multiple attempts | Reach out to FYERS Support to investigate and resolve any account-level issue. |
This error is usually resolved without any action on your part. But if it continues beyond 24 hours, contact FYERS Support for assistance with your UCC mapping or segment activation.
