Here is an example of how to trade GBPNZD or any other pair on M5. To be honest, its the same for other timeframes but M5 shows it best.
London Opens so I wait for a breakout from a recent high or Low. The pair moves in a series of higher highs with the odd bigger pullback to throw off traders. Then New York Traders either agreed and keep pushing the pound up or dump it. The rejection was clear to see around midnight so the Sell would of being the best trade of the night. So London would have only offered 60 pips but New York allowed us to win big, around170 pips if you like trade through the night.
