Quote driven and order driven financial markets
"- In a quote driven market, must every investor trade with a market        maker? In other words, two parties that are both not market makers        cannot trade between themselves directly? In a way yes, all trades go through a market maker but those trades can be orders put in place by a ""person"" IE: you, or me. - Does a quote driven market only display the ""best"" bid and ask        prices proposed by the market makers? In other words, only the        highest bid price among all the market makers is displayed, and        other lower bid prices by other market makers are not? Similarly,        only the lowest ask price over all market makers is displayed, and        other higher ask prices by other market makers are not? No, you can see other lower bid and higher ask prices. - In a order-driven market, is it meaningful to talk about ""the current stock price"", which is the price of last transaction? Well that's kind of an opinion. Information is information so it won't be bad to know it. Personally I would say the bid and ask price is more important. However in the real world these prices are changing constantly and quickly so realistically it is easier to keep track of the quote price and most likely the bid/ask spread is small and the quote will fall in between. The less liquid a security is the more important the bid/ask is. -- This goes for all market types. - For a specific asset, will there be several transactions happened at    the same time but with different prices? Today with electronic markets, trades can happen so quickly it's difficult to say. In the US stock market trades happen one at a time but there is no set time limit between each trade. So within 1 second you can have a trade be $50 or $50.04. However it will only go to $50.04 when the lower ask prices have been exhausted.   - Does an order driven market have market makers?  By definition, no. - What are some examples of quote driven and order driven financial markets, in which investors are commonly trading stocks and derivatives, especially in U.S.? Quote driven market: Bond market, Forex. Order driven market: NYSE comes from an order driven market but now would be better classified as a ""hybird market"" Conclusion: If you are asking in order to better understand today's stock markets then these old definitions of Quote market or Order market may not work. The big markets in the real world are neither. (IE: Nasdaq, NYSE...) The NYSE and Nasdaq are better classified as a ""hybird market"" as they use more then a single tactic from both market types to insure market liquidity, and transparency. Markets these days are strongly electronic, fast, and fairly liquid in most cases. Here are some resources to better understand these markets: An Introduction To Securities Markets The NYSE And Nasdaq: How They Work Understanding Order Execution"
"&gt;New Census Bureau data shows that median household net worth, excluding home equity, fell by 25% between 2005 and 2010. That decline was driven largely by the plummeting stock market, which devastated Americans' portfolios and retirement accounts.  Of course what the article *doesn't* mention, is that a significant part of that ""net worth"" was entirely illusory.  Both in the ""value of houses"" (artificially elevated by the housing bubble), and in the stock market (likewise and artificial boom, in no small part driven by the housing bubble, which itself was driven by a credit bubble)." This is similar to the overnight lending rate set by the US Federal Reserve Board. If money is more expensive to borrow (higher interest rate) then less will be borrowed.  Commercial and consumer loan rates follow up or down via market pressures (though possibly to a lesser extent in China) to adjust to the new central bank rate. Money creation is driven in part by fractional reserve banking: banks are required to have but a small percentage of deposits on hand in cash, and the rest can be lent out, deposited in another bank that has the same fractional reserve requirement, and that money can be lent out, etc.  Higher interest rates dampen this lending activity, so inflation is toned down. They are two different animals. When you rent you are purchasing a service.  The landlord, as your service provider, has to make a profit, pay employees to do maintenance, and buy materials. The price of these things will increase with inflation, and that rolls into your rent price. Taxes also are passed to the tenant, and those tend to only go upward. Market forces of supply/demand will drive fluctuation of prices as well, as other posts have described. When you buy, you are purchasing just the asset - the home. This price will also be driven by supply/demand in the market, but don't try to compare it to buying a service. Cheers!

This style should also match your personality and you should have the patience and appetite to deal with market fluctuations which can be wild in some cases (as we saw in 2008-2009).  Not an easy question to answer since everyone's situation is different and everyone has to make their own decisions. At any point of time, buyer wants to purchase a stock at lesser price and seller wants to sell the stock at a higher price.  Let's consider this scenario  Company XYZ is trading at 100$, as stated above buyer wants to purchase at lower price and seller at higher price, this information will be available in Market depth, let's consider there are 5 buyers and 5 sellers, below are the details of their orders Buyers List Sellers List Highest order in buyers list will contain the bid price and bid quantity, Lowest order in Sellers list will contain the offer price and offer quantity. Now, if I want to buy 50 Stocks of company XYZ, need to place an order first, it can be either limit or Market. Limit Order : In this order, I will mention the price(buy price) at which I wish to buy, if there is any seller selling the stock less than or equal to price I have mentioned, then the order will be executed else it will be added to buyers list Market Order : In this order, I will not mention the price, if I wish to purchase 50 Stocks, then it will find the lowest offer price and buy stocks, in our case it will be 101. if I wish to purchase 200 Stocks, then it will find the lowest offer price and buy stocks, in our case it will be 2 transactions, since entire request cannot be accommodated in single order Usually the volume(Ask Volume and Offer Volume) being displayed are all Limit orders and not Market orders, Market orders are executed immediately. This is just an example, However several transactions are executed within a second, hence we will get to know the exact value only after the order is completed(executed) "Note that the series you are showing is the historical spot index (what you would pay to be long the index today), not the history of the futures quotes. It's like looking at the current price of a stock or commodity (like oil) versus the futures price.  The prompt futures quote will be different that the spot quote. If you graphed the history of the prompt future you might notice the discontinuity more. How do you determine when to roll from one contract to the other? Many data providers will give you a time series for the ""prompt"" contract history, which will automatically roll to the next expiring contract for you.  Some even provide 2nd prompt, etc. time series.  If that is not available, you'd have to query multiple futures contracts and interleave them based on the expiry rules, which should be publicly available. Also is there not a price difference from the contract which is expiring and the one that is being rolled forward to? Yes, since the time to delivery is extended by ~30 days when you roll to the next contract. but yet there are no sudden price discontinuities in the charts. Well, there are, but it could be indistinguishable from the normal volatility of the time series." "The difficulty is that you are thinking of a day as a natural unit of time.  For some securities the inventory decisions are less than a minute, for others, it can be months.  You could ask a similar question of ""why would a dealer hold cash?"" They are profit maximizing firms and, subject to a chosen risk level, will accept deals that are sufficiently profitable.  Consider a stock that averages 1,000 shares per day, but for which there is an order for 10,000 shares.  At a sufficient discount, the dealer would be crazy not to carry the order.   You are also assuming all orders are idiosyncratic.  Dividend reinvestment plans (DRIP) trigger planned purchases on a fixed day, usually by averaging them over a period such as 10 days.  The dealer slowly accumulates a position leading up to the date whenever it appears a good discount is available and fills the DRIP orders out of their own account.  The dealer tries to be careful not to disturb the market leading up to the date and allows the volume request to shift prices upward and then fills them."
