A transaction tax will increase spreads. That is a really big argument against that such an exchange would be popular.

- crdoconnor 13y agoHFT did not reduce spreads. electronic trading did. actually sometimes hft can be a liquidity taker and thus increase spreads.
- hft_throwaway 13y agoI don't know where this meme started, but it's clearly untrue. Nanex likes to make this claim, but they claim "HFT" only started with Reg NMS in 2007. Tell me this doesn't sound like the most stereotypical HFT-style trading in 2005: http://www.bizjournals.com/kansascity/stories/2005/01/17/smallb1.html?page=all http://www.bizjournals.com/kansascity/stories/2005/01/17/sma... And it wasn't just Tradebot doing it. There were many firms already active with similar styles in the early 2000s like GETCO, ATD, Madison Tyler (now Virtu) and a bunch of smaller guys. HFT does not depend on Reg NMS, fragmentation, or rebates. HFT firms are super successful in futures markets with a consolidated limit order book and fees for both sides of the transaction.
