$IOST surged 15 points in just 15 minutes, with volume reaching 7 times its usual level and OI climbing by more than 5 points. Its notional change ranked 6th across the entire pool, while its anomaly percentile hit 100%. There are strong signs of new leveraged longs entering. The taker buy/sell ratio is 1.07, and volume and price are moving together fairly healthily. However, contract open interest is already close to its own historical extreme range, so chasing longs here offers poor risk-reward. Wait for a pullback and see if there's an entry.
