Confirm the environment
Record the account identifier, broker server and platform version before changing a connection. Check that the terminal is signed into the intended account and that the connector version is supported. A clear environment record helps prevent confusion when several terminals or accounts are open at the same time.

Review permissions and symbols
Check the permissions required by the connector and understand which actions are enabled. Verify symbol mapping, contract sizes and minimum volume for the instruments you intend to follow. Do not assume that a symbol available on a provider account exists with identical specifications on your own broker account.
Observe the health signals
A recent heartbeat indicates communication, but it does not prove that every instruction can be executed. Review account state, available margin and recent delivery records alongside the heartbeat. Test a small instruction in a demo environment and inspect the complete result, including any explanation for a rejection or adjustment.
Plan for interruptions
Document what happens if the terminal closes, connectivity is interrupted or the account becomes unavailable. Make sure you know how to pause new instructions and where to inspect existing positions. Recovery should begin with evidence about the last known state rather than an assumption that restarting alone resolves every issue.
