The Financial Post reports in its Friday edition TMX Group is introducing a "speed bump" to counter high-frequency traders. The Post's Barbara Shecter writes TMX on Thursday introduced a short-order processing delay, or speed bump, on the TMX's Alpha exchange. The move could also rival upstart Aequitas that hopes to get off the ground by next spring. "This is TMX Group's attempt to compete with Aequitas," said Doug Clark at research broker ITG Canada, which is a member of the Aequitas consortium. In high-frequency trading, computer algorithms allow traders to transact in fractions of a second to profit from tiny price differences among exchanges. The Investment Industry Regulatory Organization is in the midst of the final phase of a multiyear study into the impact HFT has on markets. Smaller retail traders complain high frequency traders make it difficult for them to fill their orders. Aequitas aims to challenge the dominant TMX Group with a marketplace it says would exclude "predatory" high-frequency trading strategies that hurt the quality and integrity of equity markets. The Alpha speed bump is expected to be in place by June, with minimum order sizes and pricing, making it less appealing for HFT traders.
