12/21/2020 8:38:08 PM GMT | By Ross J Burland NZD/USD heads back towards the day's highs on a volatile start to the week. Vaccine hopes keep the bid alive, but positioning is overbought and year-end squaring up could be on the cards. NZD/USD has rallied since London's mid-morning dealing as the US dollar flips on its head, shedding all of its gains for the day by the final hour of Wall Street. At the time of writing, NZD/USD is trading at below water by 0.37% but has climbed some 1.6% from its lows of the day, travelling between 0.7002 and 0.7123. NZD/USD burst through low volume nodes in late morning in the New York session from 0.7062 and through the session's point of control at 0.7090 to the current level.
