The rise of trading quote spam
High-frequency quoting that has skyrocketed recently, leading some in the US to think it might be time for a financial non-transaction tax similar to the one in France. The French will also impose a tax on traders who submit too many unfilled quotes.

On Monday, I posted a lovely animated gif from Nanex showing the rise of high-frequency trading. What I failed to mention is that graph doesn’t show completed trades. It shows quotes.
And according to another nice chart from Nanex, it’s high-frequency quoting that has skyrocketed, not trading.
The number of unexecuted quotes, many allegedly not intended to be executed, has thus skyrocketed.
France recently took steps to try to deter the rise in quotes. In addition to a financial transactions tax it, France will also impose a tax on traders who submit too many unfilled quotes.
In short, France will levy a financial non-transaction tax.
