The Quantum GBPX is the latest addition to our suite of currency indices, and one which we have been asked for many times, and even more so since Brexit. It is an index which has taken us some time to develop, and through a series of complex calculations draws its primary data from a basket of currencies based on the old style dollar index, the Dixie. This is converted to a chart for the British pound. The result is an accurate index which describes strength and weakness for the GBP currency in all timeframes.
