Saxo API error code
Saxo API error: InvalidModelState
What does InvalidModelState mean on the Saxo API?
One or more properties of the request are not valid. The response carries a ModelState object that names each field at fault with its error texts. Saxo's order placement page says simple syntax errors return this code.
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.
How do I fix InvalidModelState?
Read the ModelState in the response and correct the fields it names. Saxo's page says these are errors an application should prevent by sending well formed JSON and allowed values.
