Abstract

I study the effect of algorithmic trading on market efficiency, taking into account past market and limit order flows alike. I find that an exogenous increase in algorithmic trading around the introduction of the NYSE Hybrid Market leads to a significant decrease in the predictive power of surprises in market order imbalance and limit order book imbalances, especially at the outer levels of the limit order book. However, the predictive power of past returns remains largely unchanged. This suggests that algorithmic trading improves market efficiency by facilitating the incorporation of information embedded in both market and limit order flows.

纽约证券交易所混合市场推出前后的算法交易和市场效率

我研究了算法交易对市场效率的影响，同时考虑了过去的市场订单流和限价订单流。我发现，在纽约证券交易所混合市场推出前后，算法交易的外生性增长导致市场订单失衡和限价订单簿失衡的意外预测能力显著下降，尤其是在限价订单簿的外层。但是，对过去回报的预测能力基本保持不变。这表明，算法交易通过促进市场订单流和限价订单流中蕴含的信息的融入，提高了市场效率。
