- kasey_junk 11y agoBecause call markets don't actually solve any of the supposed problems of HFT. Unless the call market has a global monopoly (an impossibility that we wouldn't want if it were available) venue arbitrage is still an issue. Further, no one who proposes call markets ever talks about the matching algorithm in the face of order book imbalances. How you do tie-breakers can either still have speed advantages or has other probably worse disadvantages.
