What is the average execution size? If the average execution size is only a few hundred shares, it gives the appearance of being the front to an HFT firm that wants access to orders before they hit the market. If most of its executions are in highly liquid stocks with penny spreads, what service are they really providing? Dark pools that average 10,000+ shares and execute orders in less liquid stocks provide a valuable service.

Here in Oz there has been a trend towards the pool operated by the main exchange. My experience is that those on both sides of the trade have seen a benefit. In regards to other pools, Cavert emptor.

'Flash Boys' only provides one side of the story, and at a very simplified level at that. As per Eliad's comments above, traders who opt to use dark pools should understand how they work, as well as their own trading goals. The function of 'dark pools' is really the 'electronification' (if you will), of what happens on block trading desks all the time. When clients use those services, there are clear instructions on execution - minimum trade sizes, counterparties, order types (fill or kill, all or none, pegged, passive, agressive, etc), benchmarks, which are functions that are widely supported by EMS/OMS/ or the pools themselves. As for small investors, the same rules apply with understanding how the pools work, though in truth they would usually be excluded if they are only putting in small lot orders as they would be excluded by most institutional minimum order sizes (which should always be used - not doing so opens up the opportunity to be gamed, which is the responsibility of the trader, not the venue).

Anyone to tell the other side of the story other than 'Flash Boy'? The other side of the story would be interesting. I am not sure what the dark pool can provide but the exchanges cannot. Other than that, does dark pool charge smaller fee? Would the smaller fee over weight the benefit of transparency? Should the venue enforce the minimum order sizes instead of the trader? It seems that the traders are more interested in gaming the market.

I also believe that more buy sides are using DMA/SDMA now and block trades are not as popular as before. Is this true? It seems that DMA/SDMA are more efficient on both sides though probably not as profitable on the sell sides.
