Browser and desktop versions behave differently in Tradovate

What is causing it

They are separate applications against the same account. Layouts, local settings and browser-specific problems do not necessarily carry across, and the versions can differ.

Why this happens

Running the same service in two shells means two sets of local state. The account, positions and orders are shared because they live on the server, but anything stored locally, including layout and cached files, belongs to that installation.

This makes the pair a useful diagnostic tool. Comparing the two separates client-side problems from account-side ones in seconds.

The fix, step by step

1. Use the difference diagnostically. If a problem happens in the browser but not the desktop app, it is almost certainly a browser issue such as cache or an extension.
2. If a problem happens in both, it is account-side, such as data entitlement, a risk limit or an outage, and no amount of reinstalling will help.
3. Make sure the desktop app is up to date, as an old build can behave differently from the current browser version.
4. Do not assume a layout you built in one will appear identically in the other, and rebuild it deliberately if you need both.
5. Trade from whichever one you have actually tested your order entry in, rather than switching mid-session.

How to confirm it is fixed

You can state confidently whether the problem follows the account or stays with one client, and you have tested order entry in whichever you plan to trade from.

Stopping it happening again

Pick one as your primary and keep the other installed purely as a fallback and a diagnostic.
