Cable staying heavy; sterling weak on some commodity crosses

If you have a look at the GBP against either the AUD or the NZD on the long term charts, you will see that the pound is trading at levels which haven’t been seen in almost 4 years. I’m not sure if this means that the GBP crosses are cheap and we should be buying or whether it is entering another weak phase. The short term trend is definitely bearish so selling rallies is probably the way to go.
