Re: Norwegians convicted for outwitting trading system - OVERTURNED
This is an old one, albeit it's usually the other side working it.
There's a story in Reminiscences of a Stock Operator about how the old bucket shops would have dealers run the prices up or down a few cents on the exchange when their clients were heavily into some hot stock or other. Typically it would be something small with not much liquidity, but that a lot of punters were betting on (probably on the strength of tip by someone working for the bucketeer  ).
Most traded on a shoe string with tight stops. So the dealers washing the price a few cents would be enough of a spike to close down the punters when the next price came through on the ticker, at minimal cost in the real market and for a massive profit in the shop.
Apparently the floor traders would see this activity and comment that "the laundry is active today"  . |
