George Rodriguez, a managing director at TradeTrek Securities LLC responsible for sales, left his position at the institutional brokerage firm last week.

Rodriguez, who was responsible for sales to traditional investment advisers and pension sponsors, left over a disagreement on the direction of the firm, according to Fred Graboyes, president of TradeTrek who is managing partner and runs the firm based in Newark, NJ. TradeTrek is an agency-only brokerage firm that specializes in quantitative execution services for institutional investors, offering algorithmic trading, pre-and post-trade analysis.

TradeTrek is currently looking to replace Rodriguez with someone who has traditional experience in plan sponsors and investment advisors, says Graboyes. The firm already has the hedge fund and sell-side covered, he says.

Reached for comment, Rodriguez said the following about his departure: "Obviously, I thought long and hard about making a move having spent three years helping to grow the firm, but an opportunity has presented itself which allows me to focus more on the global and derivatives market which I strongly believe is the future of algorithmic trading, and I wish all of TradeTrek well."

Rodriguez declined to say whether he was joining another firm.
