Capital.com vs OANDA API
The same fields from the Capital.com record and the OANDA record, side by side. No winner is picked: which one suits you depends on what you are building.
Independent and unofficialNewest check
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.
