I am aware that the exchanges will halt or restrict trading when there are unexpected large drops in a stock price. Right now institutions are rushing to halt trading because a stock is rising. Regardless of what f whether you think it is the right thing to do (you can get into that as well) have you ever seen trading get restricted on a stock that is rising?

Big difference between exchange halting the trading in the exchange.

And a difference between a private or public company deciding to ban the security from.being traded on their platform.

99% of Firms Must allow you to SELL.

But a firm can decide to not let you Buy whenever they want.

A business decision is one thing.

An exchange that matches together buyers and sellers. Had the security listed and must honor all trades that goes thru their platform . They don't give a shit about anything. They have only 1 job.

Match the buyer to the seller. Make everyone market.

They have 1 rule. Create a Market. Create Liquidity.

Keep the security moving .

Make everyone happy. Do it fast. And do it again.

They don't care about anything else.

Some exchanges like to pay out kickbacks to attract brokerages to recieve FLOW , this means the customer is losing a very small amount of money. Multiplied by millions and millions of volume the pennies add up to Millions!

Order size and dollar amount matter.

The opposite of this process is called "price improvment" when you get more than you expected for a transaction you send to the exchange
