(a microcosm of a long poem)
A bank that controlled less than 10 percent of all US stock market orders was somehow able to satisfy more than half of its customers’ orders without ever leaving its own dark pool. Collectively, the banks had managed to move 38 percent of the entire US stock market now traded inside their dark pools – and this is how they had done it. “It’s a façade that the market is interconnected,” said Brad.

My smile is worth millions – literally: as I smile there are millions of gradations of movement, whole worthless fortunes in the currencies of Catatonia. I squander them – my teeth sunning themselves on endless beaches, the curvature of the horizon continued in my smile. All power lying in these repetitions, enumerations – the current in a battery racing round and round.

you stand in the dark pool in its mud you feel live things crawl across your feet maybe some feed on you but anaesthetic maws stop you from feeling the drainage of blood dark pools are private stock exchanges run by investment banks the notion is that a bank pairs off buyers and sellers of particular stocks from among its own customers before these requests are placed onto the open market this may sound like it would save customers fees they'd incur by trading through other companies but in practice many banks charge other entities to swim in their dark pools allowing these outsiders to predate on investors maybe you don’t mind if an investment banker loses a few quid but many victims are state pension funds relied on by vulnerable people through muck faster than human eyes can register squirm the high frequency traders computer algorithms that buy stocks rising in value then sell them nanoseconds later for miniscule profit per trade but profits accrue over millions of deals that each conducts every second in dark pools these traders lurk waiting for buyers to enter exploiting high speeds they learn what the customer is seeking before the customer can act they purchase shares from vendors already present within the pool they then grant the buyer’s desire at a mark-up they even reach outside the dark pool to pull in stocks on sale elsewhere how will you further investigate high frequency trading abbreviated to h.f.t.
