What does 422 Unprocessable Content mean in HTTP?
The server understands the content type and the syntax of the request content is correct, but it could not process the instructions it contains.
Risk warning: CFDs and spread bets are complex instruments and come with a high risk of losing money rapidly due to leverage. You can lose money on these products, and each provider publishes its own loss figure under FCA rules. You should consider whether you understand how they work and whether you can afford to take the high risk of losing your money. Automated and API trading can amplify losses through bugs, connectivity failures and runaway orders.

What should I do about 422 Unprocessable Content?
Read the API's own code and message in the body, correct the values and send the request again. A retry without a change will fail in the same way.
This page is an independent explanation in plain words. The definition itself is in the source it was read from, which is the authority if the two ever differ.
