I fully support IEX's application and I urge Lawmakers to do the same. Not only am I tired of High Frequency Trading algorithms destroying market structure, I am also tired of Latency Arbitrage, and the lack of transparency in the US markets. I have every confidence that the structure employed by IEX will go some way to ameliorating these distortions in the US equity markets. If things continue as they are then I will no longer be an investor in US Markets.
