BlockBeats News, September 8th, On-chain data analyst Murphy released a market analysis stating that the Volume Delta Balance (VDB) of perpetual contracts measures the recent futures market, the short-term trend of the buy/sell power delta (30-day moving average) relative to a longer-term market benchmark (90-day median) to determine whether the current market is biased towards long or short positions, and to observe whether this power is strengthening.
Since early August, Binance and other trading platforms' VDB has fallen into negative territory, indicating that perpetual contract traders— a speculative group in this market— have increasingly embraced a bearish bias in the subsequent period. However, this indicator exhibits extremely high volatility, so a comparison between "short-term" and "medium-term" is used to observe the direction and extent of the deviation to confirm whether this negative bias will develop into a sustained trend (red arrow in the chart).
The current trend of VDB is gradually reversing (green arrow in the chart), indicating that bullish sentiment is recovering, and traders' bearish bias is gradually diminishing. Based on historical data, if this trend continues, the market is expected to experience a rebound rally.
