To SEC, 


Volume-based transaction pricing creates a conflict of interest for market makers, exchanges, and high-volume traders, where their interests are diametrically opposed to low-volume traders. This practice promotes de-facto fracturing of liquidity and inhibits price discovery of equities. It is your responsibility to foster a competitive pricing environment for all market participants. 


If you would like a comprehensive economic analysis of the impact of this rule change, I would be happy to do it for you with our economist team at the Colorado School of Mines. 


All proposed changes need to be forward looking, so we may operate in a 21’st century marketplace. 


Thank you 


Scott Pollan, Professional Trader
