Based on the integration of two disciplinary fields (MIS and finance), this paper focuses on the micro-foundations of flash crashes, considered as socio-technical failures. A historical analysis allows us to identify four historical periods which each links micro-characteristics (such as speed and volume of traded transactions as well as traders’ technologically-based strategies) to the macro-emergence of extreme phenomena (financial crashes). History is used to calibrate an agent-based model in order to contribute to a better understanding of systemic issues raised by financial institutions and regulatory agencies. Our results contrast with the general opinion that high-frequency traders provoke financial instability because of their use of automated trading based on speed and increasing number of traded transactions. We show that the introduction of heterogeneous high-frequency traders does not necessary amplify the depth of the crash as some of them play a role of liquidity providers and do not follow chartist-based strategies.
