After October, the price trend of $ENA showed a clear upward trend, and this positive change can be strongly supported by the performance of trading volume and Median APY.

First, trading volume began to increase gradually in October, indicating that market activity has increased and more investors have begun to pay attention to ENA again and participate in its transactions. The increase in trading volume often means that the market's interest and confidence in assets are increasing, which provides strong support for the rebound in ENA prices.

In addition, Median APY also showed signs of recovery during this period. The increase in Median APY means that the yield of staking ENA has increased, which has attracted more users to participate in staking and investment, further enhancing the market's demand and trust in ENA.

Combined with the increase in trading volume and the rise in Median APY, it can be inferred that the upward trend of ENA prices is based on the recovery of market confidence and wider user participation. These factors have jointly promoted the positive trend of ENA after October and laid a solid foundation for future growth.
