The RBNZ Monetary Policy Statement caused prices to spike up. Whenever there is an important news coming such as an Interest rate decision, it means there will be a lot of volatility as the announcement is made. It is better to close any position in that currency for safety reasons before the announcement. Unless, there is a clear sign of a certain direction the market will take, we can take a chance if worth it and risk our allowed risk to take profit in the movement caused by the news release.
