$BIRB saw a sharp 15m drop: -5% on 6x volume, with the OI anomaly percentile hitting 99%, ranking second across the entire pool. Interestingly, the structure looks more like long deleveraging—the price fell and OI contracted, with a notional change of -369K, taker flow imbalance of -5.6%, and a buy/sell ratio of 0.89. Selling pressure is building, but it doesn't look like a full-on panic selloff. However, 1h OI is still up +5.82%, which suggests the positions built up earlier haven't been fully cleared. This kind of divergence between longs and shorts can keep grinding on. The 24h trading volume of 36M isn't small, so keep watching to see whether OI actually contracts; otherwise, any rebound will be hollow.
