$ARC has made an interesting move: up 3.51% in 15m, with volume surging to more than 7 times normal and a taker buy/sell ratio of 1.95—buyers are clearly rushing in. But looking closely at OI, both the 15m and 1h readings are edging down, while notional change is positive. Price up, open interest down: a classic short-covering rally, not fresh longs entering.

Price has already broken above the highs of nearly 20 consecutive 5m candles. OI is at the 99.2nd percentile of abnormal readings, ranking third across the entire pool. This kind of extreme reading has already fired up short-term sentiment. However, 24h trading volume is only 11M, and liquidity is thin: it can rise quickly, but it can fall just as fast.

Be careful chasing this kind of setup. Once the short-covering momentum runs out, if no new capital steps in, the price can easily return to where it started. Watch to see whether OI turns positive—that would be the real signal.
