Oh, yah. However, the contract will be settled when it's settled. Haven't looked, but I assume 6 September is the settlement date, insofar as it's the statutory date (if I'm not mistaken -- always a possibility) by which the Mexican election governors must declare a new President.
Exited my long Pesos position way too early; left upwards of $1100 per contract on the table. Still, a good solid winner though. (mutters at self...)
