Time-dependent relations between gaps and returns in a Bitcoin order book
研究了比特币订单簿中缺口大小与资产收益变化之间的因果关系，发现这种关系仅限于瞬时因果，不涉及动态过程。
Several studies have shown that large changes in the returns of an asset are associated with the sized of the gaps present in the order book. In general, these associations have been studied without explicitly considering the dynamics of either gaps or returns. Here we present a study of these relationships. Our results suggest that the causal relationship between gaps and returns is limited to instantaneous causation.
