Determining the top or bottom of Virtual Money requires a comprehensive analysis combining technical indicators, on-chain data, market sentiment, and cyclical patterns. Here are the key methods and practical applications:

 

📊 1. technical indicator

Trading Volume and Open Interest

Top Signal:

The price has reached a new high but the trading volume has shrunk, forming a "top divergence," indicating a depletion of buying pressure.

The sudden drop in open interest and the increase in trading volume suggest that bulls are taking profits, and the trend may reverse (for example, when ETH rises to $4800, open interest dropped by 15%).

Bottom signal:

Prices have hit a new low, but trading volume has drastically shrunk (extremely low volume), or there may be a panic sell-off followed by a rebound with increased volume (such as a single needle bottom).

Open interest surged and prices stopped falling, indicating that bears may cover their positions (for example, BTC rebounded after hitting a bottom of $30,000).

2, Long-Short Ratio and Funding Rate

Top Signal:

The long and short positions in the account are extremely high (e.g., >2), retail investors are overly bullish, and the main players may reverse to harvest.

The funding rate remains positive and high, and the perpetual contract premium is excessive, indicating an overbought risk.

Bottom signal:

The long and short account ratio is extremely low (e.g., <0.5), retail investors are panicking and selling, and the market may be close to the bottom.

The funding rate is significantly negative, and short sellers need to pay high fees, which may trigger a short covering rebound.
