Sunday/Monday trading tends to be erratic – especially during the summer and holiday periods. I prefer not to trade Sundays/Mondays because the setups have a lower probability of being successful…no point in starting the week off on the wrong foot. After a week of moving down the GBP was up a bit overnight, but not convincingly – in any manner. Most pairs traded without much of a range.
Be very selective in what you trade, keep your rules simple and be patient!
