Detailed Description

Slippage model that mimic the effect brought by market impact, i.e. consume the volume listed in the order book

<remark>Almgren, R., Thum, C., Hauptmann, E., & Li, H. (2005). Direct estimation of equity market impact. Risk, 18(7), 58-62. Available from: https://www.ram-ai.com/sites/default/files/2022-06/costestim.pdf</remark> <remark>The default parameters are calibrated around 2 decades ago, the trading time effect is not accounted (volume near market open/close is larger), the market regime is not taken into account, and the market environment does not have many market makers at that time, so it is recommend to recalibrate with reference to the original paper.</remark>
