We perform computer simulations of the minimal model in order to verify liquidity scaling laws. A logarithmic correction to the scaling law for midmarket variance is observed, but not for bid-offer spread or its fluctuation, because they are fundamentally different quantities. Time to midmarket sale ($\\tau_S$) is found to scale as 1/J while its fluctuation goes as $0.73/J$. A ``reduced'' time ($\\tau_{reduced}$) is also studied, and found to scale in a non-trivial way. Asymmetric fluxes are introduced to the minimal model and analytical result derived earlier for the speed of the moving midmarket agrees with numerical results. Simulation of the two-liquid model which describes a market with both market order and limit order traders, reveals widening of the bid-offer spread when the flux of market order traders exceeds that of limit order traders. The variation of the spread with the fraction of market-order traders is investigated. The formula for asymmetric fluxes is applied to the two-liquid model and its predictions are found to agree with experiment. The critical point is approximately determined, and the ratio of the midmarkets for $f = 0.0$ and $f = 0.5$ (where $f$ is the fraction of market-order traders) is calculated.", "revisions": [ { "version": "v1", "updated": "2001-01-31T18:51:23.000Z" } ], "analyses": { "keywords": [ "two-liquid model", "numerical analysis", "market microstructure", "limit order traders", "market order traders exceeds" ], "note": { "typesetting": "LaTeX", "pages": 69, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2001cond.mat..1474C" } } }
