How do I prevent a signal from reaching the wrong cTrader account?

What this means in practice

Use server-side authorization, immutable connector-to-account mappings, environment separation for demo/live, validation before dispatch and audit logs that record the resolved account. Fail closed when routing is ambiguous. This page is specifically about “How do I prevent a signal from reaching the wrong cTrader account?”, so each scenario below is explained by its own mechanism instead of sharing one generic diagnosis.

Real-world scenarios

Scenario A — Demo/live mix-up

Inspect the mechanism named by “Scenario A — Demo/live mix-up” directly. Record its input, the state immediately before it and the first observable output that differs from the intended result. For Scenario A — Demo/live mix-up on question 70, use that evidence specifically to answer “How do I prevent a signal from reaching the wrong cTrader account?”; keep it separate from the evidence for the other scenarios on this page.

Scenario B — Stale connector token

Inspect the mechanism named by “Scenario B — Stale connector token” directly. Record its input, the state immediately before it and the first observable output that differs from the intended result. For Scenario B — Stale connector token on question 70, use that evidence specifically to answer “How do I prevent a signal from reaching the wrong cTrader account?”; keep it separate from the evidence for the other scenarios on this page.

Scenario C — Ambiguous account mapping

Inspect the mechanism named by “Scenario C — Ambiguous account mapping” directly. Record its input, the state immediately before it and the first observable output that differs from the intended result. For Scenario C — Ambiguous account mapping on question 70, use that evidence specifically to answer “How do I prevent a signal from reaching the wrong cTrader account?”; keep it separate from the evidence for the other scenarios on this page.

What to check

• target connector/account identity
• exact broker symbol
• normalized order parameters
• cTrader response and final position/order state

Practical rule

For “How do I prevent a signal from reaching the wrong cTrader account?”, change only the first layer whose evidence no longer matches the intended action. Preserve signal identity, timestamps and final cTrader state, and reproduce execution-affecting changes on demo before live use.
