# **Fidelity Active Trader Pro Login or Sync Issues (2025 Solutions) **Meta Description: Fidelity Active Trader Pro Login or Sync Issues-2025 Solutions: Step-by-step fixes for launch failures, connection errors, and data-sync delays. Understand how to troubleshoot safely calling Fidelity Support- 888-684-9487, on Fidelity --- Why Active Trader Pro May Not Open or Synchronize Fidelity's **Active Trader Pro (ATP)** is a very powerful real-time trading platform. However, especially after software updates or changes in network environments, it may show login or synchronization problems. Typical triggers include: Outdated Java or .NET components * Cached credentials or corrupted config files * Antivirus/firewall blocking data ports (443 / 4433) * Server maintenance or account-permission mismatch * Operating-system security patches that reset permissions --- ## **Step-by-Step Fix Guide **1. Verify Fidelity System Status * Go to the [Fidelity System Alerts page](https://www.fidelity.com/security/fidelity-system-updates). * If maintenance is listed, wait until it's finished before retrying. **2. Check Network and VPN * Disconnect from any VPN or proxy; they can prevent ATP from reaching Fidelity's quote servers. * Whitelist `*.fidelity.com` and ports 443 / 4433 in the case of a corporate network **3. Update Active Trader Pro Launch the **Fidelity Update Manager** or reinstall from your account’s Downloads page. Old builds may fail the authentication process following recent security upgrades in 2025. **4. Clear Cached Profiles 1. Quit ATP 2. Go to `Documents\\Fidelity Active Trader Pro\\Profiles`. 3. Rename the folder to `Profiles_old`. 4. Restart ATP and log in fresh. *(This forces a rebuild of layout and login cache.)* **5. Verify Windows and Browser Settings * Verify that system date/time and regional settings are correct. SSL certificates can reject mismatched clocks. * If you log in via browser first, clear cookies for `fidelity.com`. 6. Check Firewall and Security Software * Disable third-party antivirus temporarily, or add an exclusion for `atp.exe`. * Immediately turn protection back on after testing. 7. Sync and Streaming Delays If charts or quotes are lagging: * Open **Settings → Data → Streaming Mode**, select *Real-Time (High Speed)*. * Check the watchlist limit (< 250 symbols). * Close unused windows; each tile consumes bandwidth. **8. Re-Authenticate Sometimes, “Login failed (1013)” messages occur due to the expiration of tokens. * Choose **File → Logout**, then re-enter your Fidelity username and password. * Enable two-factor authentication--it adds stability and security. **9. Use Alternate Device or Web Platform If problems persist with desktop, then sign in at [Fidelity.com/trade](https://www.fidelity.com/trade) to check account access. If web login works, then the problem is local to your computer—not your Fidelity credentials. --- ## **Preventing Future Login or Sync Problems | Cause | Prevention Tip | | -------------------- | -------------------------------------------------------------------- | | Software out of date | Enable auto ATP update. | | Overloaded layout | Limit streaming windows to active symbols. | | Frequent disconnects | Use wired Ethernet or 5 GHz Wi-Fi. | | Credential errors | Refresh password every 90 days and store in Fidelity’s secure vault. | --- Do humans and animals apprehend the world in one and the same way?
