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Outdated Java or .NET components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.
