There is one particularly useful technical analysis tool which is easily available to forex traders but more difficult for traders of other asset classes.
One of the old adages of technical analysis is ‘when in doubt, turn your chart upside down’. This was easy in the days of paper charts but became nearly impossible in the computer age, though it has become a bit easier for traders charting on mobile phones or tablets.
In forex markets, which are based on pairs trading, it's easy to flip a chart over by reversing which of the two currencies in the pair is the base currency.
In the example charts, traders wondering if USD/CAD is topping may look to CAD/USD for signs of confirmation or rejection.
In addition to the chart pattern itself, USD and CAD are a particularly interesting pair to compare in this way, because there are large groups of traders who look at each chart. USD/CAD is the global convention used by traders around the world.
CAD/USD, however, is widely used by the Canadian media and Canadian public, so key levels on either chart can have an influence on analysis and trading, and become potential pivot points like USD/CAD $1.2500 and CAD/USD $0.7500, for example.
In these charts it's also worth noting how the wedge patterns and RSI divergences reinforce each other.
