Let me share one of my findings.

Through my observation, I found that when the price of $ETH rises or falls and is accompanied by a continuous increase in trading volume over a short period, there is a high probability of a reversal in the market in a short time.

For example, during the upward trend, if the increase becomes smaller while the trading volume continues to grow, it is very likely that the price will not go up and then fall down.

Conversely, if the decline slows down, there may even be a rebound.
