Final cut: ARB is still the setup to watch if you're active.

In the last four hours, ARB is down 7.98 percent, and it's posting volatile, two-way action, tight spreads but sharp moves. The immediate level is 0.17174; a break toward 0.175 would hint at recovery, but lose 0.1701 first and 0.165 is the next support below. This is the one name where what happens next will matter most today.
