What does 200 (no security definition) mean on the Interactive Brokers API?
No security definition has been found for the request. The contract does not match anything in the IB database, usually an incorrect or missing parameter.
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 200 (no security definition)?
Check symbol, secType, exchange, currency and expiry; use reqContractDetails to confirm the contract.
