Market Rigging Explained

We received trade execution reports from an active trader who wanted to know why his larger orders almost never completely filled, even when the amount of stock advertised exceeded the number of shares wanted. For example, if 25,000 shares were at the best offer, and he sent in a limit order at the best offer price for 20,000 shares, the trade would, more likely than not, come back partially filled. In some cases, more than half of the amount of stock advertised (quoted) would disappear immediately before his order arrived at the exchange. This was the case, even in deeply liquid stocks such as Ford Motor Co (symbol F, market cap: $70 Billion). The trader sent us his trade execution reports, and we matched up his trades with our detailed consolidated quote and trade data to discover that the mechanism described in Michael Lewis’s “Flash Boys” was alive and well on Wall Street.

  1. So Michael Lewis told the whole world that this was going on and that there’s a new exchange that prevents these shenanigans… so why aren’t people trading over there on the IEX?

  2. Because the “Flash Boys” are doing everything they can to kill the HFT story and keep trades off IEX. And it’s working.

  3. “Kill the HFT story”? Are you kidding? Who does not know about this?
