Orders rejected: this is often a rule, not a bug in WebTrader platforms

What is causing it

On a prop or funded account the provider's risk rules are enforced inside the platform, and an order that breaks one is refused before it goes anywhere.

Why this happens

A rule rejection is a decision, so it is consistent: the same order in the same conditions is refused every time, instantly, with no market involvement. A technical fault is a failure, so it is erratic, usually affects closing as well as opening, and normally comes with other symptoms such as prices that have stopped moving.

The most reliable single test is asymmetry. Providers virtually always let you reduce risk, so being able to close but not open is designed behaviour rather than a broken platform.

The fix, step by step

1. Try to close or reduce an existing position. If closing works and opening does not, that is a rule, not a fault.
2. Check your provider's dashboard for remaining daily loss, remaining drawdown, size limits and open position limits.
3. Check the clock against any restrictions on news events, the weekend close and permitted trading hours.
4. Try a much smaller size, and then a different instrument, to narrow down whether the block is about size, that instrument, or the account as a whole.
5. Treat it as technical only if prices are stale, a connection warning is showing, or closing fails too. Then reload and check the provider's status page.
6. Contact the provider with the account number and the time of the rejection and ask which rule fired, as they can see the reason and you cannot.

How to confirm it is fixed

The same order is accepted once the limiting condition has changed, for example after the daily reset or at a smaller size, with nothing else altered.

Stopping it happening again

Keep the rule sheet and the dashboard beside the platform and size positions so normal variance never brings you to a limit.
