Let's zoom in on ARB, the standout mover:

ARB is up 29.21 percent today, the biggest outlier. It's holding inside a range, but price is pressing right against resistance at 0.215 dollars, last trade was 0.21339 dollars. If it pushes through 0.215 dollars and holds, that would confirm the breakout; if it fades, quick profit-taking could follow. Volatility is high and open interest is climbing, so expect sharper moves either side of the level.
