There are cases when brokers will buy the tickets after they get the order.

A broker buys 200 shares instead of the 100 requested.

Some brokers bought the notes themselves, he added, "and they feel that they're victims too."

That does not mean brokers cannot buy for themselves.

Except, of course, for the fact that the brokers bought their shares in 1993 at much cheaper prices.

The broker buys for himself first, at the current price, but his order may drive the price up for the customer.

Next, the broker buys for the customer, further raising the price, and then he sells his own contract at a profit.

When we had a different database, brokers bought both.

Nasdaq uses a dealer system, in which competing brokers, called market-makers, buy and sell stock for their own accounts.

What is new here, and good, is that such a requirement would come into play if a broker bought stock at a lower price.
