      Knapman has been meeting asset managers and hedge funds over the last month to discuss how the emergence of dark pools and high-frequency trading has affected the equity markets.
Equity markets have seen drastic changes recently, with technological advances increasing the prominence of high-frequency trading and the EU's Markets in Financial Instruments Directive (MiFID) paving the way for a plethora of new electronic trading platforms.
 
The 
FSA  has recently green-lighted dark pools from Chi-X, Bats, Nasdaq OMX, Nyse Euronext and the LSE. However, earlier this year the regulator deemed Nyfix's Euro Millennium dark pool non-compliant with the latest interpretations of the 
MiFID  rulebook.
 
 
Similar concerns in the US recently led to senator Charles Schumer calling on the 
SEC  to ban "flash" trades where users are given an advanced peek at unfilled orders ahead of the wider market.
 
The US watchdog had already outlined plans to step up its scrutiny of dark pools amid concerns about the risks posed to market transparency and integrity by the proliferation of off-exchange trading venues.
