the extension draws attention to a potential price movement. By doing so, this allows participants to review the prices of the orders that they have entered and if appropriate add, delete or amend.
The extension also indicates to investors that there may be the potential of getting a good deal for the security in question, thereby encouraging their involvement and so stabilising the price through the inputting of acceptable orders.
Ultimately, though, the point of the extension is to ensure any resulting price is a fair reflection of the security. It also allows MMs to balance their books intra day.
