Listen to the crap in this video.
If there are 3 people at the same price level in the order book, and you are #1, a broker can come along & step in front of all 3 people, including you & grab a matching order.
TOTAL GARBAGE. No other dark pool or ECN does that.
Michael Lewis wrote a whole book promoting a rigged dark pool.
Be careful if you trade on IEX and are seeing orders filled at your price level & someone else is getting your executions.
