This presentation summarizes a study that uses an artificial market model to investigate the effect of tick size in competition between stock markets. The model replicates key stylized facts and microstructure statistics. Simulation results show that a market will not lose trading volume share if its tick size is smaller than the 1-tick volatility of returns or if it is smaller than 1/10 of another market's tick size. A market's trading volume share decreases more rapidly when its tick size is larger than the 1-tick volatility. Empirical analysis of two real markets shows similar relationships between tick size and volatility and trading volume share.
Regulations' Effectiveness for Market Turbulence by Large Erroneous Orders us...Takanobu Mizuta
?
The document discusses a study by Takanobu Mizuta from Sparx Asset Management on the effectiveness of regulations for market turbulence caused by large erroneous orders, utilizing a multi-agent simulation model. The findings from two experiments show that erroneous orders lead to price declines not only during but also after their occurrence, and that price variation limits are effective in mitigating price fluctuations if the limit time span is shorter than the duration of erroneous orders. Overall, this research highlights the need for shorter price variation limits in high-frequency trading environments to prevent market turmoil.

The document discusses the instability of financial markets and investigates optimizing investment strategies using an agent-based model developed by Sparx Asset Management. It highlights that the inability of investors to accurately estimate market impacts and the resulting 'optimization instability' can lead to unpredictable time evolution of market prices. The study concludes that financial markets are inherently unstable, making it difficult to build reliable predictive models for price dynamics.
L'intelligence artificielle utilisée sur les marchés financiersTakanobu Mizuta
?
Ce document explore l'application de l'intelligence artificielle (IA) sur les marchés financiers, expliquant ses forces, ses faiblesses et son fonctionnement. L'auteur décrit également l'évolution de la perception publique de l'IA, en soulignant la désillusion post-boum et la nécessité de comprendre comment l'IA fonctionne pour évaluer ses applications potentielles. L'article met en avant que l'IA, bien qu'efficace dans certains domaines comme le jeu de go, n'égale pas l'intelligence humaine et reste un outil qui nécessite une grande quantité de données.
