$BSB 15 minute-level direct breakthrough, down 1.22%, with the closing price falling below the lower bound of the past nearly 20 five-minute K-line range. Trading volume has swelled to 3.45 times the usual level. This drop isn’t a low-volume, slow bleed—it looks like someone is genuinely dumping.

What’s even more worth noting is the contract data: 15-minute OI only fell by 0.09%, but nominal changes dropped by 110K; on the 1-hour dimension, nominal shrinkage is 132K as well. What does this mean? It’s not a showdown between long and short big players, but more like leveraged positions being liquidated and longs actively withdrawing. The difference in passive vs. active trading is -29%, the buy/sell ratio is 0.55, and sellers are in full control. Abnormality across the whole pool ranks #24; volume anomaly is near the top, and the nominal change ranking of #37—this combination of data is a textbook deleveraging move.

The order book only has about $10 million in 24 hours. In situations like this, technical levels are basically made of paper. First, see whether the order book can hold steady—don’t rush to catch flying knives.
