Market mechanics
What is a dark pool and how does institutional block trading impact retail traders?
By Easy Money Scanner · Educational reference · Not investment advice
The short answer
A dark pool is a private trading venue where institutions execute large block trades anonymously, away from public exchanges, which can delay the price impact visible to retail traders until after the trade reports.
How it works
Because dark pool trades aren't shown pre-trade, retail investors see less transparent order-book depth, though trades must still be reported to the consolidated tape shortly after execution under SEC rules.
An example
A pension fund selling a million shares might route through a dark pool to avoid moving the public market price before completing the trade.
Risk & limitations
Reduced pre-trade transparency can mask genuine supply/demand imbalances, making technical signals on lit exchanges less reliable for heavily dark-pool-traded stocks.
