IF we look at the Supply and Demand for the Aussie, we can see a stack of Sell Side between .70 and .75.
Looking down there seems to be only 2 Demand Zones below.
Once the buy orders are eliminated from the .66 level,
it will likely be a quick ride to .60 level , because in the past .60 -.66 was a compression zone.
This area leaves very little demand behind.
On chart is a trade in line with the bigger picture and Aussie to continue the downtrend against a strong US Dollar.
