>but instead routed to "alternative trading systems" (ATS) e.g. "dark pools" where your purchase has no effect on the price of the security.
1. alternate trading systems are obligated to print their trades to the ticker, albeit at a slight delay compared to official exchanges
2. price is dictated by supply and demand, not the trade being publicly announced on exchanges. Trading volumes not being public probably has some non-zero effect on price discovery, but claiming that it has "no effect" is absurd.
