If you catch the GBPAUD entry last night, this trade could turn into a mini position trade. If the 1.6400 area fails, we should see a bigger push down. Some of your may be tempted to take the 100+ pips now, but a lot more pips are waiting. I would at least leave part of your position open ;)
Keep an eye on news. News could cause a few spikes up, but the Sterling should continue to lose value in 2017.
