On September 7th articles posted that a Brexit deal would most likely not happen. If you look at the daily chart from the 8th on we were completely bearish with GBP. The end of last week into today there are now high speculations that the deal indeed will happen. Again look at the daily chart and you will see the Bulls are trying to push. The transition period ends on December 31st and cannot be extended. Look for daily articles that continue to speculate the deal will happen and wait for some rise and start trading GBP and EUR.
