Consider the charts below;
1 GBP/USD
2 AUD/USD
3 GBP/AUD

If "Aussie" gains on the USD as recent prop trader indications suggest, then it would be good to watch Sirling against USD, If Stirling declines and breaks a support line then the GBP/AUD pair will be very interesting to look at for a significant Long gain for short positions. Possible estimation for this is around 15th February. Apologies the images are a little mixed up but I have numbered them.
