It can be seen that the contract price has been rising continuously with several bullish candles, and the trading volume below these bullish candles has also been increasing accordingly. This kind of price and volume coordination in the rising market is the most ideal. Next, as the price continues to rise, the trading volume below no longer increases in sync, forming a divergence at the top. This kind of behavior of rising prices with decreasing volume at the top indicates insufficient bullish energy, and the market may have reached a cyclical peak.
Without the support of trading volume, prices cannot sustain an upward trend, and there is also a suspicion of inducing buying when prices rise. When investors encounter this kind of rising market with decreasing volume, long positions should be reduced or exited.
