Record the exact environment
List the platform and terminal build, program version, symbol including any broker suffix, chart timeframe and preset. Note whether the issue happens in a historical test or on a demo chart, and when you first observed it.
Keep the relevant logs
Copy a small relevant portion of Experts and Journal logs. Describe the steps you took and the expected action. If an error is visible on the chart, include the whole message. Remove account passwords, keys and unrelated private information.
Avoid changing everything at once
Use a controlled test environment and change one relevant condition at a time. A connection issue, settings mismatch and unmet strategy condition require different investigations. The first assessment should identify what can be reproduced and what further evidence is missing.
