$ERA This move gained 3.83% in 15m, with OI moving in tandem. The 1h notional change is +4.82%, and it hasn’t contracted for several consecutive periods—this looks less like simple short covering and more like new leveraged longs entering. The taker buy/sell ratio is 1.12, with a 5.8% trade imbalance. Sentiment is bullish but not euphoric. The OI anomaly percentile is 90.3%, ranking #40 across the full pool. It’s not the most eye-catching, but the persistence is worth watching to see whether volume picks up and price holds steady.
