Let's dig into that ARB move.
ARB lost 10.39 percent in the last day, the biggest slip among majors. It's still inside a range, trading at 0.17221. Upside is capped by resistance at 0.17562, support rests at 0.165. Volatility here is the highest on the board, with funding elevated, but open interest fell 7.9 percent in 24 hours, so some traders have already called it quits. If ARB pushes below 0.165, risk is to the downside and things could move quickly.
