Orders rejected in Quantower

What is causing it

Insufficient margin, an account limit, an order type the broker does not support, or an instrument your account is not permitted to trade.

Why this happens

Quantower forwards the order to the broker on that connection and reports back what the broker says. A rejection is the broker's risk system speaking, so the fix lies with margin, permissions or limits rather than the platform.

Order type support is the one genuinely platform-related cause, because an integration exposes a specific set of order types and anything outside that set cannot be sent.

The fix, step by step

1. Read the rejection message, since the wording comes from the broker and usually names the actual reason.
2. Check the margin required for that contract, and remember futures margin is often much higher outside the intraday session.
3. Check the order type you used is supported by that broker through this platform, because integrations do not always support everything the broker offers.
4. Check whether your account has a maximum position size or other risk limit, which is common on evaluation and funded accounts.
5. Confirm the market is open for that contract and the account is approved for that product.
6. If the message is unclear, take it to the broker on that connection, since only they can see why their system refused it.

How to confirm it is fixed

A corrected order is accepted and appears as a working order in both Quantower and the broker's own records.

Stopping it happening again

Know your account's margin and limits, and establish which order types the integration supports before relying on one.
