This is old news. This happened in 2014.
There was a lot of talk about hard landing of Chinese economy in the financial media.
You should know this that Australian economy is now highly linked with the Chinese economy.
Today Australian economy is highly dependent on trade with Chinese economy.
Over 30% of the Australian exports are now headed towards China.
Fundamental analysis counts a lot in currency trading.
Read this blog post in which I analyze what happened when Chinese Factory Output figures released were not good.
AUD/USD fell 500 pips in a week on Chinese Factory Output poor figures.
Now keep this in mind.
When you trade currencies always try to keep an eye on the fundamentals if you want to catch the big trends.
