$SIREN This 15m drop fell 4.75%, with volume immediately surging to 5.54x. It really looks like some positions got swept out. OI 15m -1.59%, 1h -1.73%, with price and open interest both dropping together, a classic long deleveraging move, not new shorts coming in to dump it. Active trading imbalance was -16.9%, buy/sell ratio 0.71, so the sell pressure is quite obvious, but the notional change is only in the 700k to 1M U range, not especially large. OI abnormal percentile is 95%, ranked #5 across the whole pool, and it has been sustained for several periods. This structure looks more like position contraction after a chain of stop-loss triggers. 24h turnover is 38M, with enough depth; it's not the kind of small pool that gets blown through on the first dump. At this level, if you're chasing shorts, be careful of a rebound after the deleveraging ends; if you're trying to buy the dip, wait until OI stabilizes. Don't rush to catch it before the leverage is fully flushed out.
