What does TRAILING_STOP_LOSS_ON_FILL_CLIENT_ORDER_ID_ALREADY_EXISTS mean on the OANDA API?

Filling the order would have created a trailing stop loss order with a client order ID that is already in use. OANDA lists this value as an order cancel reason: it appears in the reason field of an order cancel transaction.

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.
