Awesome, but quite standard for major broker dealer banks. Any major market making broker dealer will have tech designed to protect itself from being on the wrong end of trades with better informed market participants. And those better informed market participants may well be market making HFT firms. See recent discussion about BARCs FX trading [1]. Larry Harris' class Trading and Exchanges has an excellent explanation of the microstructure dynamics of markets makers and informed traders [2], which I comment on here [3].
