报告题目：Reinforcement Learningand Evolutionary Equilibrium in Limit Order Markets（限价订单市场中的强化学习与演化均衡）  

报告摘要: With the rapid rising and ubiquity of algorithmic trading in limit ordermarkets, we show that an information-based reinforcement learning can bevery effective to find an evolutionary equilibrium. By performingcomparative dynamics in equilibrium, we show that the order choiceof buy-or-sell and market-or-limit orders for informed traders mainlydepends on their information about fundamental value, while uninformed traders tradeon a short-run momentum of informed market orders. The learning improves marketliquidity and increases uninformed traders' liquidity supply and informedtraders' liquidity consumption, generating order flow persistence andhump-shaped order books. It also improves traders' welfare and pricediscovery. The results shed an economic insight into the market practice ofusing machine learning in trading.
