Something is wrong and you cannot tell what in Sierra Chart

What is causing it

The explanation is usually already recorded in the message log, which most users never open.

Why this happens

Sierra Chart reports most of what it does to the message log rather than through pop-up dialogs. That keeps the interface quiet, but it also means the diagnostic information is there whether or not you are looking at it.

Because the log records the service's own responses, it usually shows whether a failure came from the platform, the data service or the broker, which is the first thing any support desk will want to know.

The fix, step by step

1. Open the message log window from the Window menu and read the most recent entries.
2. Reproduce the problem while the log is open, so you can see exactly what is recorded at the moment it happens.
3. Look for entries about connection, authentication, permissions, symbols or studies, as these cover the large majority of problems.
4. Copy the relevant lines when contacting support, whether that is Sierra Chart, your data provider or your broker, since the log identifies which of them owns the problem.
5. Do not change several settings at once while diagnosing, because the log becomes much harder to interpret.

How to confirm it is fixed

You can point to the specific log entry that corresponds to the problem, rather than describing symptoms.

Stopping it happening again

Make opening the message log your first step whenever something changes, before adjusting settings.
