There are several types of markets and I will shortly state and describe them.
The first digit is direct search markets, and it is the least organized of markets. Buyers and sellers simply seek each another out directly, as if you are shopping around in an auction. A good example of this, is the sale of a used table where the buyer and seller found each another online.

The next field is brokered market, where you have someone who takes the task of finding the right person who is going to acquire securities from you or sell you theirs. A good example of this is the actual realty market, where you really can’t acquire a concern without a professional actual realty broker to take tending of all the tasks and find proper homes.

Markets in which traders specializing in particular assets (stocks, bonds, boats, cars, etc…) acquire and sell for their own accounts are called the dealer markets. A quick example of this is the over-the-counter (OTC) market. Dealer markets spend traders on search fees because people participating in the mart can easily look up the price range that they want to purchase or sell in the market.

The most integrated area is an auction market, where all traders get together at digit locate to acquire and/or sell an asset. The New York Stock Exchange (NYSE) is a great example of this auction market. An advantage if this, over other markets, is that no digit has to search across dealers to find the best prices. If all participants are in digit area then the general consensus can find a mutually agreeable price and spend the bid-ask spread.
