This was a serious topic of discussion by many traders when we first got wind of this being built. It was around the same time that the hedge-funds figured out how truly screwed they were holding massive blocks of stock that were essentially illiquid pieces of paper if attempted to be traded in any size.
That was in 2006 right as the machines took all the humans out of the flow. The options markets were targeted first as the algos were tested on small markets. This was a demonstratable and cheap way to restrict order flow by changing the bid/ask offers in penny increments as the orders were clicked into the system (AI keyscore). If you were stupid and used a market order you were never alerted to this game.
If any of you traded options in starting in 2006 with limit orders you saw this. It was the test phase of unleashing it upon the entire market.
Ever wonder why all of these large institutional holders NEVER sell much?
THEY CAN"T.. Any attempt at selling size would result in an automatic shutdown of the stock per trading rules. It would then start the downward cycle of /open/close/open/close etc throughout the days/weeks ahead.
These institutions are trapped, know it and can do little about it.
Go ahead…sell a large chunk of anything…impossible unless a pre-arranged deal made that hits tape shortly before close.
