According to BlockBeats, CryptoQuant CEO Ki Young Ju said that whales are preparing for the next round of altcoin rally. Except for Bitcoin and Ethereum, the volume of altcoin limit buy orders is increasing, indicating that a strong buying wall is being established.

In the exchange platform, market orders generate "taker volume", while limit orders generate "maker volume". Whales and institutions often use limit orders to trade large amounts to avoid slippage.

The indicator is calculated by calculating the cumulative sum of the difference between the buy and sell orders, using a 1-year moving window. If an uptrend is present, it means that the buy orders are increasing, indicating that more strong buy walls are forming.
