There are no people running MMs in this market. So, no computers setting up codes to buy or sell. All they have to do is adjust their spread. Besides, computers can talk to each other without sending signals to the public. Good god!
The 500 share tranches are simply partial trades. As we all know mm spreads also have a quantity. They are only required to trade that quantity before they can adjust the spread. If you look carefully, you should see the price paid shift slightly after each tranche.
