unsupervised access to markets by external trading bodies is an open invitation to abuse the market mechanisims and manipulate prices in the short term. In today's high speed market, unsupervised access can do serious damage before it is even recognized. To go even a bit further, high speed trading platforms can do the same.They only exist to increase volume and manipulate the daily or momentary pricing of a given security. Why should high speed traders be allowed to trade on unsettled funds when the general public is not. Maybe you should address this issue as well. Increased liquidity is not the holy grail, fair market pricing is. Stand up for the individuals your existance is supposed to help.
