Profit from the RBNZ Rate Reduction

On Jan 28, the Reserve Bank of New Zealand (RBNZ) cut the cash rate by 1.5 percent to 3.5 percent. It was 0.5 percent more than average estimates. I made 84 pips of profit by selling nzdjpy after the FOMC announcement and less than 30 minutes before the RBNZ rate decision (I closed it about 15 minutes after the announcement). I made also profit from selling audusd but the position closed before the announcement.
