tick_value_unavailable

Signal webhook: the terminal gave no tick value for the symbol, so the loss at the stop can't be worked out.

HTTP 422. Nothing reached the broker.

Likely cause: The symbol’s tick value or tick size is missing, often just after the terminal started.

What to do: Use a fixed size in lots, or send a new alert later. Nothing was sent.

Retry: No. The same request gets the same answer; change something first.
