What does Unknown order type mean on the Interactive Brokers API?
Web API status 400 BadRequest, with the error message "Unknown order type" (the vendor's wording). Interactive Brokers lists it on its order error details page. The vendor's context: the order type provided is inaccurate.
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.
