English to Spanish Bus/Financial Finance (general)

Hi, friends,

Even though my main specialty is finance, I must admit that every time I find "FX agency model execution" my mind gets a bit collapsed. The term model can be difficult to translate: "Bróker de FX/divisas con una ejecución avanzada"?
Or "ejecución avanzada de un bróker de divisas"? There is no more context. They are usually banner-like texts. "

Thanks.
