The sterling continues trying to advance, but if found a strong resistance at 1.6727/14. Yesterday it tried to break it twice and, since then, it's been losing ground. The dollar is now trying to break the support where yesterday and Monday there was a pull back. If it finds support there, the price will be on a very well defined lateral and it's likely it will try to climb to exit it. If it loses the level, the price will slide down to 1.6607, the last support before getting to yesterday's low at 1.658. Breaking it could take the pair to an important sale, getting even to 1.6532 dollars per pound.
