The most salient result is that velocity should not be reduced too fast, hence δ should be below but close to one. 4). With ‘improved’ parameter values for both de and ps, both methods performed equally well for small models, but ps still was superior for large models. 20. 6 gives the results. 05 performed best on average. At the same time, reducing z deteriorated the worst solution. Thus for too small step sizes, ta more often seemed to get stuck in local, but globally suboptimal, minima. 2. Parameter sensitivity ps for δ = 1.

Static strategy pre-determines order trading schedule and will not change during the process of trading. This strategy can not adapt to changing environment. For example, an aggressive strategy that places only market orders to buy can not change its aggressiveness if the market price keeps moving up. On the other hand, adaptive strategy adapts to changing market conditions such as market price movements, volume profiles due to special events such as new announcements or fed indicators, as well as changes in volatility, by altering their aggressiveness of trading adequately.

Market Impact As investors transact shares in the market they cause market impact (price impact) in the stock. Buy orders are associated with increasing prices and sell orders are associated with decreasing prices. The market impact is typically decomposed into permanent and transitory components which provide estimates of the information and liquidity costs of the trade [20]. 48 W. Cui, A. Brabazon, and M. O’Neill Make decisions Order Matching Mechanism Fig. 1. Price Formation Due to its importance, there is much research on the causes of market impact [22].
