Nanex ~ 20-Dec-2012 ~ Dark Pool Tardiness 2
This is a 2nd example showing how Dark Pool trades appear much later than they should.
During market wide momentum ignition events: where trades execute in hundreds of symbols
at the same millisecond, we've noticed the dark pool trades always, always, always come
quite a bit after lit market trades.
The 3 charts plot trade execution prices (y-axis)
between 0 and $145 during a 2 second period of time starting at right before a news
event at 10am EST. Each pixel width corresponds
to 2 milliseconds of time. SPY trades show up
near the top at $145. What these charts show, is that dark pool trade execution are
consistently reported late for all symbols. We think traders and investors that use
consolidated market data deserve better.
