Abstract:

In order-driven financial market, order flow imbalance is the main driving force for price movement. To deeply explore the price impact of order flow imbalance, dynamic limit order book, and quantify time-varying characteristics of multi-level order flow imbalance are reconstructed, then the price impact and cross impact are discussed. The mechanism and trader's behavior characteristics behind the result are explored. Our empirical analysis results show that,first,multi-level order flow imbalance contains deeper levels information of limit order book. It can provide higher explanatory power for the contemporaneous price impact. Second, from the perspective of multi-asset trading, the information of other limit order book is also included in multi-level order flow imbalance, multi-asset models with cross-impact do not provide additional explanatory power for contemporaneous impact. Third, the post-double-selection granger causality testing can effectively identify the continuous guidance relationship between different sample stocks' multi-level order flow imbalance and realize the portrayal of cross impact. Multi-level order flow imbalance not only contains private information held by informed traders, but also implies behavioral characteristics of multi-asset traders.

Key words: limit order book, order imbalance, deeper levels, price impact, cross impact
