**[Analysis: Traders' Short-Selling Bias Gradually Weakens, Market Poised for a Rebound]** BlockBeats News, September 8 – On-chain data analyst Murphy released a market analysis stating that the Volume Delta Balance (VDB) of perpetual contracts measures the short-term trend (30-day moving average) of the buy-sell power difference in the recent futures market relative to the longer-term market benchmark (90-day median). This is used to determine whether the current market leans bullish or bearish and to observe whether this force is strengthening. Since early August, the VDB on Binance and other trading platforms has dropped into negative territory, indicating that perpetual contract traders—a highly speculative group in the market—have shown an increasing tendency toward short-selling during this period. However, this indicator is highly volatile, so comparing "short-term" and "mid-term" trends is necessary to observe the direction and magnitude of the deviation, in order to confirm whether this negative bias will develop into a sustained trend (red arrows in the chart). The current VDB trend has begun to gradually reverse (green arrows in the chart), suggesting that bullish sentiment is recovering and traders' short-selling bias is weakening. Historical data indicates that if this trend continues, the market could be poised for a rebound.
