I really like the system, it actually works, the best I've seen in years. Don't bother with the emails, they're too slow for this. Use the Instant Trade Messenger (click on "Open ITM" at the top of this page). Test trade it in simulation first to make sure that you can execute the trades as quick and precise as is required.

Es muy bueno, pero hace tantas operaciones y tantas cancelaciones que se hace dificil de seguir y de aprovechar.
