Evidences are coming forwards more and more about how rigged and or manipulated the market has become. The interesting side is that free enterprise and smart brain power have been able to push the rise of the machine to such a level that the new resulting “ecosystem” has been somwhow facing its own limits. Can we say that HFT is somehow the plague of the markets? I would say yes in the sense that we realize more and more that they tend to not contribute positively to the overall developpment of the markets. Are Flash Crashes signals that the current cannibalism in the system is due to the dominance of HFT?
If nature is a good guide, plagues do not last and I guess that some of the smart guys you will see in this video, have understood that ver well. Enjoy
