side_not_allowed

Signal webhook: the webhook only opens trades on the other side.

HTTP 422. Nothing reached the broker.

Likely cause: allowed_sides is long or short, and the alert asked for the other side.

What to do: On a reversal the close still runs. Change allowed_sides if this side should trade. Nothing was sent.

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

Listed under Signal webhooks (TradingView) in Errors. Send the error’s requestId to support and we can find the request.
