What a misleading article. Vinny has been in finance for decades, and all ZH says about it is, "Although, in all fairness to Viola, he did serve as former Chairman of the NY Merc."
He was Chairman (and major shareholder) of Nymex when they were establishing the Dubai Merc and before they went public. He made the vast majority of his fortune from Nymex, not from Virtu.
Virtu, in its present form, was born out of a merger with Madison Tyler Trading 3-4 years ago.
