Markets remains stable when the regulatory capital of broker dealers is sufficient to absorb losses of the firm. Algorithmic trading can potentially wipe out net capital in a manner of minutes.

Fortunately is enabled to haircut or show the effect of trading in net capital in real time. We look to notify the exchanges by electronic transmission free of charge to halt trading when markets are threatened.

The website on market structure stated diverse ideas are welcome. Either provide a reason why this would not work or collaborate with us on securing market stability.

Thanks for your consideration.
