Recently, OKB has been very strong and the big pie is falling, but it is pulling against the trend. From a daily level perspective, continuous large bullish lines have been pulled up, and the volume can be synchronously amplified, completely breaking out of the bottom market. A long upper lead has appeared above, and generally this trend will be followed by a rebound, gradually filling the upper lead. That is, OKB is expected to continue to impact the previous high of 140 pressure level. If it can still rebound to around 100 or below in the short term, spot OKB can be bought at the bottom in batches
