Hi Rabbit,
I understand your comment/clarification.

Both CU and CZ are limit down at moment.

Here is CME link to futures limits:
http://www.cmegroup.com/trading/Price-Limit-Update.html

They are still showing the 30 cents.

Apparently the limits are somewhat fixed but CME doesn't post the 2nd and 3rd day limits, so I guess they may change them based on the trading circumstances.

I had recorded 45 cents last time but Limitup just posted 40 cents, so maybe I made a mistake.

Check that link after the market closes, I'm sure they will show the new trading limit before long after.

Thanks, Lee
