If you are a regular at ForexLive during the Asia session you'll see me reminding from time time on the limits to trade onshore yuan

  • USD/CNY is permitted only to trade plus or minus 2 % from each day's reference rate

That limitation does not apply to the offshore yuan

  • USD/CNH

And, wow , beast mode …

5 minute candles, past 4 have a 400+ points range

Don't see that everyday

If you prefer trading majors, AUD/JPY is copping it
