Can you sell stocks/commodities for any price you wish (either direct or market)?
"You answered your own question ""whether someone buys is a different thing"". You can ask any price that you want. (Or given an electronic brokerage, you can enter the highest value that the system was designed to accept.) The market (demand) will determine whether anyone will buy at the price you are asking. A better strategy if you want to make an unreasonable amount of money is to put in a buy order at an unreasonably low price and hope a glitch causes a flash crash and allows you to purchase at that price. There may be rules that unravel your purchase after the fact, but it has a better chance of succeeding than trying to sell at an unreasonably high price." "In other words, does the market have control over sale numbers or do I? You both do, just like for the bike.  You have control over the price you ask, and the buyer has control over the price they pay.  If the two do not align, no sale takes place. Your question uses the words ""sell"" and ""sale"" ambiguously.  You can decide to ask for any price you want.  You cannot actually sell anything until someone agrees to buy what you are offering." "I think for this a picture is worth a thousand words.  This is a ""depth chart"" that I pulled from google images, specifically because it doesn't name any security.  On the left you have all of the ""bids"" to buy this security, on the right you have the ""asks"" to sell the security.  In the middle you have the bid/ask spread, this is the space between the highest bid and the lowest ask.  As you can see you are free to place you order to the market to buy for 232, and someone else is free to place their order to the market to sell for 234.  When the bid and the ask match there's a transaction for the maximum number of available shares.  Alternatively, someone can place a market order to buy or sell and they'll just take the current market price. Retail investors don't really get access to this kind of chart from their brokers because for the most part the information isn't terribly relevant at the retail level."
That's up to you. If you instruct your broker to sell shares purchased in specific lots, they can do that -- but doing so requires that you and/or they track specific fractional lots forever afterwards so you know what is still there to be sold. FIFO simplifies the bookkeeping. And I am not convinced selecting specific lots makes much difference; the government gets its share of your profits sooner or later. For exchange contracts, yes. A trader can close a position by taking an offsetting position. CME's introduction to Futures explains it quite well (on page 22).  Exiting the Market Jack entered the market on the buy side,   speculating that the S&P 500 futures price would move higher. He has   three choices for exiting the market: You can execute block trades on the options market and get exercised for shares to create a very large position in Energy Transfer Partners LP without moving the stock market. You can then place limit sell orders, after selling directly into the market and keep an overhang of low priced shares (the technical analysis traders won't know what you specifically are doing, and will call this 'resistance'). If you hit nice even numbers (multiples of 5, multiples of 10) with your sell orders, you can exacerbate selling as many market participants will have their own stop loss orders at those numbers, causing other people to sell at lower and lower prices automatically, and simultaneously keep your massive ask in effect. If your position is bigger than the demand then you can keep a stock lower. The secondary market doesn't inherently affect a company in any way. But many companies have borrowed against the price of their shares, and if you get the share price low enough they can get suddenly margin called and be unable to service their existing debt. You will also lose a lot of money doing this, so you can also buy puts along the way or attempt to execute a collar to lower your own losses. The collar strategy is nice because it is unlikely that other traders and analysts will notice what you are doing, since there are calls, puts and share orders involved in creating it. One person may notice the block trade for the calls initially, but nobody will notice it is part of a larger strategy with multiple legs. With the share position, you may also be able to vote on some things, but that solely depends on the conditions of the shares. "They are not selling stocks. They are selling OJ futures contracts. Selling a futures contract at 142 gives the buyer the right to buy a fixed number of pounds of orange juice concentrate (""OJ"") on a future date at 142 cents per pound. The seller has an obligation to suppy that fixed number of pounds of OJ to the buyer on the future date for 142 cents per pound. When the seller turns around and buys future contracts at 29, the seller gets the right to buy OJ on a future date at 29. This ""zeros his position"" -- meaning he's guaranteed himself the ability to deliver the pounds of OJ he was obligated to supply when he sold futures contracts at 142. And since he'll only have to pay 29 cents per pound, and he'll be selling the OJ for 142 per pound, he'll walk away with 113 cents of profit for every pound sold. You can read a blow-by-blow account of what Winthorpe and Valentine did at the end of ""Trading Places"" here and here. Note that what they did would not be legal today under the ""Eddie Murphy rule"", which prohibits trades based on illicitly obtained government information." If the share is listed on a stock exchange that creates liquidity and orderly sales with specialist market makers, such as the NYSE, there will always be a counterparty to trade with, though they will let the price rise or fall to meet other open interest.  On other exchanges, or in closely held or private equity scenarios, this is not necessarily the case (NASDAQ has market maker firms that maintain the bid-ask spread and can do the same thing with their own inventory as the specialists, but are not required to by the brokerage rules as the NYSE brokers are).  The NYSE has listing requirements of at least 1.1 million shares, so there will not be a case with only 100 shares on this exchange. I am going to. Like I said I have not traded options much in general, but I can see a lot of potential in derivatives in general, and it makes me kind of grin. In the case of commodities, the advantages are really apparent. The only problem I see with stock options is that they expire, and thus if you are more long term bull on a stock, it would be harder. But for things like commodities, that are shorter term any ways and require margin, it makes a lot of sense IMO. I could see how you could gain a larger diversification through options (being able to bet on Russell 2000, S&amp;P, etc. ) or esoteric markets (electricity).   I will look up that book that you mentioned. Thanks man. Which is what [flash trading](http://www.investopedia.com/financial-edge/0809/flash-trading-wall-streets-latest-scam.aspx) is for.   edit: I promise you, you could. You would just need a faster line. I promise that's why the NYSE banned it. However, that still doesn't mitigate the problem of creating your own exchange. Rule 610 (Google for it) stands that if Bid and Ask are the same, the market is considered Locked, and the exchange must stop all trading. So the same person can't quote the same bid and ask price. However, HFTs have found ways to circumvent this limitation when exchanges created special order types for them, e.g. Spam-and-Cancel I've been a retail trader for close to 7 years and while I have a specialized futures account, I use Interactive Brokers for my other trading. They charge per share or contract rather than per trade (good for smaller accounts  or if you want to piece into and out of positions). You can also trade just about anything. Futures, options, options on futures, individual stocks, ETFs, Bonds (futures), currencies. The interface is pretty good as well. I have seperate charts (eSignal) so I'm not sure how good their charting is Bid and ask prices are the reigning highest buy price and lowest sell price in the market which doesn't mean one must only buy/sell at thise prices. That said one can buy/sell at whatever price they so wish although doing it at any other price than the bid/ask is usually harder as other market participants will gravitate to the reigning bid/ask price. So in theory you can buy at ask and sell at bid, whether or not your order will be filled is another matter altogether. Depending on your broker, you can buy these stocks directly at the most liquid local exchanges. For instance, if you are US resident and want to to buy German stocks (like RWE) you can trade these stocks over InteractiveBrokers (or other direct brokers in the US). They offer direct access to German Xetra and other local markets. I am able to place an 'all or none' order with my broker. But doing so reduces the number of potential sources to fulfill the order. As others have mentioned, try a limit order to get a specific price. "As far as I know, the answer to this is generally ""no.""  The closest thing would be to identify the stock transfer company representing the company that you want to hold and buy through them. (I have held this way, but I don't know if it's available on all stocks.)  This eliminates the broker, but there's still a ""middle man"" in the transfer company. Note this section from the Stock transfer agent Wikipedia article: A public company usually only designates one company to transfer its stock. Stock transfer agents also run annual meetings as inspector of elections, proxy voting, and special meetings of shareholders. They are considered the official keeper of the corporate shareholder records. The decision to have a single transfer company is a practical one, ensuring that there is one entity responsible for recording this data - Hence even if you could buy stock ""directly"" from the company that you want to own, it would likely still get routed through the transfer company for recording." "Stocks prices are determined whenever a buyer and seller agree to trade at a given price. The company (you use AAPL as an example) doesn't set its own stock price. Rather, the investors set the price every time it trades. There's no ""official"" price -- just the last trade. Likewise, you can offer to trade a stock at whatever price you want: that's the definition of a limit order. You might not find a willing buyer or seller at that price, but you can certainly open an order. Stock quotes that you get from your broker or a finance web site reflect the price as last traded. These quotes are updated throughout the trading day and the frequency and delay varies amongst quote providers. Like Knuckle-Dragger suggests in the comments, there are ways to get real-time quotes. It's often more helpful to think in terms of bid/ask instead of ""official price"". See this question for details." "I guess there are accepted channels for this sort of thing, but I don't really understand why. Couldn't anyone sell them to anyone else at any time in any kind of market? I mean, if I had a friend who was talking the the IPO up, couldn't I have just said, ""Hey Fred, I'll sell you a Facebook share in two weeks time for thirty five bucks"" and be done with it?  Do exchanges provide legal services? Is there a law that says you have to go through them? And even if you *did* have to go through them, why wouldn't multiple exchanges list them instead of just one, and why wouldn't an exchange start listing them from the minute the gun fired (or before)?"
