This is exactly why NOBODY should be in the market.

It is corrupt to the core, and run by psychopaths.

So the Russians/al Qaeda/Iran staged a dry run?

Karl Denninger wants the exchanges to require any order placed to remain valid for two seconds. That would instantly stop this nonsense - but some powerful people would be inconvenienced.

Put a one penny tax on every trade. Just one penny. Mom ‘n Pop investors can afford to pay one cent when they cash out of their investments easily. Just one cent.

Agree 100%. This is precisely why I got out of the market forever in very early 2008. Haven’t looked back.

There’s lots of other ways to make money.

This is excellent strategy.

If I was offered a system in which I was allowed to place orders, have the system tell me how many and at what price my orders would be filled by others, and then cancel them milliseconds later, I would do exactly what these programmers did.

It’s like playing poker with the ability to look at the other guys’ hands. Who wouldn’t do that?

What has to happen is the trading systems have to disallow the withdrawal of orders. Otherwise, you just get this: gaming. If you let poker players to place mirrors around the room to look at the other guys’ hands, don’t be all surprised when they do exactly that!

This started in the 1980’s. It was blamed for the October 1987 crash. Since then HFT has accounted for more and more of the volume:

Well I have to disagree with this article. If the orders were put out and then cancelled before executed then there was no trading. Until they are executed they are just orders. How can non executed trades be 4% of the market? Doesn’t make sense.

Ask the author, Linette Lopez that question.

I have no answers.

I'm 100% for this. I'd also institute a per share penalty fee for orders placed and then withdrawn. Doesn't need to be much but it would eliminate fake orders placed to shape the market.
