it's called the 'dark pool'

a large trading house has clients that want shares sold

it also has clients that want shares bought

the shares are sold to the client who wants them without the trade being part of the open market

this is done off-screen, in house, and is known as dark pool trading

being with a large brokerage enables better fills

i've been the recipient of dark pool trading

at the time, i was equally mystified how i could get mine sold when sellers ahead of me were still in the queue

dark pool trading is not illegal

nor is it sinister in any way

algorithms are sinister

take home information:

dark pools refer to the in-house, off market movement of shares from one client to another at market rates
