JPY Crosses- Crash and burn? or temporary adjustment?

I’m looking at the JPY and commodity crosses , specifically AUD/JPY and AUD/USD.Both of these have broken 2 support levels and just seem to be tumbling down hill. Can anyone charts out the next support resistance levels if I want to enter a trade on these because they say the AUD/USD currently at 0.8183 will eventually head for 0.8300 and the AUD/JPY currently at 99.20 is headed for 100.40, how on earth did they get these levels and when will be a good time to buy into it…

I have been trading AUD/JPY all the time.

Now, however, i have found it to be trendless for the time being so i have abandoned it.
