How to use FX Barometer?
Upper currency futures are the strongest ones.
Lower currency futures are the weakest ones.

Example:
In Medium Term chart, US Dollar is strongest & JPY is weakest speaking from Foreign Exchange Investment Cash Flow Theory. Therefore, due to US Dollar Over Bought status, SHORT USD/JPY will be the best REVERSAL TRADE followed by USDCHF Short.

OR...

If the fundamentals are well placed with technicals, buying strongest currency would be rewarded as well. For example, AUD vs. USD in short term chart. USD strongest, AUD weakest.
