LMAX Exchange CEO, David Mercer, comments that the recent public perception of High Frequency Trading as being the poorest incarnation of Big Finance could be the result of particular journalistic approach and the reality is that HFT is here to stay.

It could be public perception can be changed with a combination of greater education and more responsible journalism.
