What does The contract description specified for %S is ambiguous; you must specify the currency mean on the Interactive Brokers API?
Interactive Brokers prints this message, in the vendor's wording, as a second row under code 203 in its TWS API error table. The vendor's note says the contract definition is incomplete and that the currency must be included. The %S mark is a placeholder the page prints as it is.
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 The contract description specified for %S is ambiguous; you must specify the currency?
Include the currency in the contract definition, as the vendor's note says.
