The Price Impact of Order Book Events from a Dimension of Time

Larger orders may be put relatively deep to soothe their influence on the price. Slower traders sometimes use a limit order on the medium-distanced layers to mitigate their inability to control for short-term variance in price. In all of these cases, traders express their expectations for the price in the deeper layers. Our results coincide with this view of shared information between layers, increasing with depth. So, controlled by Chinese SEC on limit orders’ cancellation, the state of imbalanced order flow dominates the market since the proportion of cancellation is low compared with total limit orders in Chinese stock market. The order flow imbalance , proposed by Cont et al. , is defined as the imbalance between supply and demand at the best bid, and ask prices better explain price changes.

Findings from Cont et al. seem to give an intuitive picture of the price impact of order book events, which is somewhat simpler than the ones conveyed by previous studies. Meanwhile, Cont’s linear model with average high R-squared also excludes trades, which seem to carry little to no information about price changes after the OFI is taken into account simultaneously. We propose a new linear model to explain the price move by Level-2 high-frequency data in Chinese mainland stock market. In Chinese stock market, the cancellation ratio is very low, and imbalanced order flow prevails most of the time in the trading periods. In particular, when market’s liquidity is booming, our model’s explanatory power and R-squared increased sharply. And the correlations of OEI are very high that may be exploited to predict the price move in the next time window for doing high-frequency trading. The term order book refers to an electronic list of buy and sell orders for a specific security or financial instrument organized by price level.
