Arbitrage is fundamentally a very low-risk trading technique if it is well-controlled.

Our experience, combined with our algorithms (the early detection of opportunities, or even anticipation) and trading infrastructure (interconnections, transaction speed, and low latency, in particular), mean that we can complete the majority of transactions in a sufficiently short timeframe so that the impact of a price change is minimal. 

Moreover, one of our prudential rules is to never invest more than 20% of your assets in the same arbitrage.
