You can actually watch trading taking place on the web by soriginally the BATS Exchange

until it was purchased by the CBOE in $2016.$ This market is somewhat unique in that the

"order book," meaning the list of all buy and sell orders, is public in real time. As show, I

have captured a sample of the order book for Intel $($INTC$).$ On the top in blue are sell

customer has specified the most he or she will pay $($for buy orders$)$ or the least he or she

will accepted $($for sell orders$).$ The inside quotes $($the highest bid, or buy, and the lowest

ask, or sell$)$ in the market are shown in bold face.

If you visit the site, you can see trading take place as orders are entered and executed.

Noticed that on this particular day, about $2\mathrm{.}8$ million shares of Intel had traded on the

CBOE Market. At that time, the inside quotes for Intel were $1,500$ shares bid at $$52\mathrm{.}32$

and $800$ shares offered at $$52\mathrm{.}33.$ This is not the entire order book for Intel as there are

more buy orders below $$52\mathrm{.}28$ and more sell orders above $$52\mathrm{.}37.$

Question:

Go to

markets.cboe.com$/$us$/$equitieslinks to an external

site. and look up the order book for Microsoft $($MSFT$).$ What

are the inside quotes for Microsoft?
