The name of this website is just a name, it has nothing to do with real dark pool liquidity block trades. Dark Pool Liquidity is the trading volume created by institutional orders that are unavailable to the public. The bulk of dark pool liquidity is represented by block trades facilitated away from the central exchanges. Also referred to as the "upstairs market", or "dark liquidity", or just "dark pool." The dark pool gets its name because details of these trades are concealed from the public, clouding the transactions like murky water. Some traders that use a strategy based on liquidity feel that dark pool liquidity should be publicized, in order to make trading more "fair" for all parties involved.
