# 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.

Source: https://tickwire.io/docs/errors/tick_value_unavailable/

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.
