英文摘要：
  The price impact for a single trade is estimated by the immediate response on an event time scale, i.e., the immediate change of midpoint prices before and after a trade. We work out the price impacts across a correlated financial market. We quantify the asymmetries of the distributions and of the market structures of cross-impacts, and find that the impacts across the market are asymmetric and non-random. Using spectral statistics and Shannon entropy, we visualize the asymmetric information in price impacts. Also, we introduce an entropy of impacts to estimate the randomness between stocks. We show that the useful information is encoded in the impacts corresponding to small entropy. The stocks with large number of trades are more likely to impact others, while the less traded stocks have higher probability to be impacted by others.

中文摘要：
单笔交易的价格影响通过事件时间尺度上的即时响应进行估计，即交易前后中点价格的即时变化。我们计算出了相关金融市场的价格影响。我们量化了交叉影响的分布和市场结构的不对称性，并发现跨市场的影响是不对称和非随机的。利用谱统计和香农熵，我们将价格影响中的不对称信息可视化。此外，我们还引入了影响熵来估计股票之间的随机性。我们证明了有用信息被编码在对应于小熵的碰撞中。交易量大的股票更有可能影响其他股票，而交易量少的股票受其他股票影响的可能性更高。
