It's actually quite simple. You're actually confusing two concept. Which are taking a short position and short selling itself. Basically when taking a short position is by believing that the stock is going to drop and you sell it. You can or not buy it back later depending on the believe it grows again or not. So basically you didn't make any profit with the drop in the price's value but you didn't lose money either.  Ok but what if you believe the market or specific company is going to drop and you want to profit on it while it's dropping. You can't do this by buying stock because you would be going long right? So back to the basics. To obtain any type of profit I need to buy low and sell high, right? This is natural for use in long positions. Well, now knowing that you can sell high at the current moment and buy low in the future what do you do? You can't sell what you don't have. So acquire it. Ask someone to lend it to you for some time and sell it. So selling high, check.  Now buying low? You promised the person you would return him his stock, as it's intangible he won't even notice it's a different unit, so you buy low and return the lender his stock. Thus you bought low and sold high, meaning having a profit. So technically short selling is a type of short position. If you have multiple portfolios and lend yourself (i.e. maintaining a long-term long position while making some money with a short term short-term strategy) you're actually short selling with your own stock. This happens often in hedge funds where multiple strategies are used and to optimise the transaction costs and borrowing fees, they have algorithms that clear (match) long and short coming in from different traders, algorithms, etc. Keep in mind that you while have a opportunities risk associated.  So basically, yes, you need to always 'borrow' a product to be able to short sell it. What can happen is that you lend yourself but this only makes sense if:
The short answer to your initial question is: yes. The option doesn't expire until the close of the market on the day of expiration. Because the option is expiring so soon, the time value of the option is quite small.  That is why the option, once it is 'in-the-money', will track so closely to the underlying stock price. If someone buys an in-the-money option on the day of expiration, they are likely still expecting the price to go up before they sell it or exercise it. Many brokers will exercise your in-the-money options sometime after 3pm on the day of expiration.  If this is not what you desire, you should communicate that with them prior to that day.
What you're describing is called timing the market.  That is, if you correctly predict when the market will drop, you can sell before the drop, wait for the drop, then buy after the drop has occurred.  Sell high, buy low. The fundamental problem with that, though, is: What ends up happening, on average, is you end up slightly behind.  There's quite a lot of literature on this; see Betterment's explanation for example.  Forbes (click through ad first) also has a detailed piece on the matter. Now, we're not really talking HFT issues here; and there are some structural things that some argue you can take advantage of (restrictions on some organizational investors, for example, similar to a blackjack dealer who has to hit on 16).  However, everyone else knows about these too - so it's hard to gain much of an edge. Plenty of people say they can time the market right, and even yourself perhaps you timed a particular drop accurately.  This tends to lead to false confidence though; how many drops that you timed badly do you remember? Ultimately, most investors end up slightly down when they attempt to time the market, because of the transaction costs (if you guess two drops, one 'right' and one 'wrong', and they have exactly opposite gains/losses before commissions, you will lose a bit on each due to commission), and because of the overall upward trend in the market (ie, if you picked at random one month a year to be out of the market, you'd lose around 10% annualized gains from doing that; same applies here). All of that aside, there is one major caveat: risk tolerance.  If you are highly risk tolerant, say a 30 year old investing your 401(k), then you should stay in no matter what.  If you're not - say you're 58 and retiring in a few years - then knowledge that there's a higher risk time period coming up might suggest moving to a less risky portfolio, even at the known cost of some gains.
I believe this depends on the broker's policies. For example, here is Vanguard's policy (from https://personal.vanguard.com/us/whatweoffer/stocksbondscds/brokeragedividendprogram): Does selling shares affect a distribution? If you sell the entire position two days or more before the dividend-payable date, your distribution will be paid in cash. If, however, you sell an entire position within the two day time frame of the security's payable date, the dividend will be reinvested, resulting in additional shares. Selling these subsequent shares will require another sell order, which will incur additional commission charges. Dividends which would have been reinvested into less than one whole share will be automatically liquidated into cash. If you want to guarantee you receive no fractional shares, I'd call your broker and ask whether selling stock ABC on a particular date will result in the dividend being paid in shares.
"Great answer by @duffbeer. Only thing to add is that the option itself becomes a tradeable asset. Here's my go at filling out the answer from @duffbeer. ""Hey kid... So you have this brand-new video game Manic Mazes that you paid $50 for on Jan 1st that you want to sell two months from now"" ""Yes, Mr. Video Game Broker, but I want to lock in a price so I know how much to save for a new Tickle Me Elmo for my baby sister."" ""Ok, for $3, I'll sell you a 'Put' option so you can sell the game to me for $40 in two months."" Kid says ""Ok!"", sends $3 to Mr Game Broker who sends our kid a piece of paper saying: The holder of this piece of paper can sell the game Manic Mazes to Mr Game Broker for $40 on March 1st. .... One month later .... News comes out that Manic Mazes is full of bugs, and the price in the shops is heavily discounted to $30. Mr Options Trader realizes that our kid holds a contract written by Mr Game Broker which effectively allows our kid to sell the game at $10 over the price of the new game, so maybe about $15 over the price in the second-hand market (which he reckons might be about $25 on March 1st). He calls up our kid. ""Hey kid, you know that Put option that Mr Game Broker sold to you you a month ago, wanna sell it to me for $13?"" (He wants to get it a couple of bucks cheaper than his $15 fair valuation.) Kid thinks: hmmm ... that would be a $10 net profit for me on that Put Option, but I wouldn't be able to sell the game for $40 next month, I'd likely only get something like $25 for it. So I would kind-of be getting $10 now rather than potentially getting $12 in a month.
"I interned for about six months at a firm that employed a few technical analysts, so I'll try to provide what little information I can. Since the bulk of the intra-day trading was decided algorithmically, technical analysts had two main functions: This basically boils down to my answer to your question. There are still enough people, trading firms, etc. who believe in candlestick charting and other visually subjective patterns that if you notice a trend, pattern, etc. before the majority of traders observing, you may be able to time the market successfully and profit. This is becoming increasingly dangerous, however, because of the steps I outlined above. Over time, the charting patterns that have been proven effective (often in many firms individually since the algorithms are all proprietary) are incorporated into computer algorithms, so the ""traders"" you're competing with to see the pattern are increasingly low-latency computer clusters less than a few blocks from the exchange. Summary: Candlestick charting, along with other forms of subjective technical analysis, has its believers, and assuming enough of these believers trade the standard strategies based on the standard patterns, one could conceivably time the market with enough skill to anticipate these traders acting on the pattern and therefore profit. However, the marginal benefits of doing so are decreasing rapidly as computers take over more trading responsibility. Caveats: I know you're in Australia, where the market penetration of HF/algo traders isn't as high as in the US, so it might be a few more years before the marginal benefits cease to be profitable; that being said, if various forms of technical analysis proved wildly profitable in Australia, above and beyond profits available in other markets, rest assured that large American or British trading firms would already have moved in. My experience is limited to one trading firm, so I certainly can't speak for the industry as a whole. I know I didn't address candlestick charts specifically, but since they're only one piece of visual technical analysis, I tried to address the issue as a whole. This somewhat ties into the debate between fundamental or technical analysis, which I won't get into. Investopedia has a short article on the subject.
BATS CHi-X Europe is a market maker. They provide liquidity to the order books of different kinds of equities on certain exchanges. So the London Stock Exchange lists equities and the order books show the orders of different market participants. Most of those market participants are market makers. They allow others to complete a trade of an equity closer to the price that persons wants, in a faster time period and in larger amounts, than if there were no market makers providing liquidity.
Whenever you trade, it's critical to completely understand the risk you're taking and the bet you're actually making, not just the bet you think you're making. Also, according to my ""algorithm"" a sale only takes place once the stock rises by 1 or 2 points; otherwise the stock is held until it does. Does this mean you've removed the lower limit order? If yes, then you expose yourself to downside risk. What if the stock has traded within a range, then suddenly starts declining because of bad earnings reports or systemic risks (to name a few)? If you haven't removed the lower limit order, then point #4 still stands. However, I never specified that the trades have to be done within the same day. Let the investor open up 5 brokerage accounts at 5 different firms (for safeguarding against being labeled a ""Pattern Day Trader""). Each account may only hold 1 security at any time, for the span of 1 business week. How do you control how long the security is held? You're using limit orders, which will be triggered when the stock price hits a certain level, regardless of when that happens. Maybe that will happen within a week, or maybe it will happen within the same day. Once again, the bet you're actually making is different from the bet you think you're making. Can you provide some algorithms or methods that do work for generating some extra cash on the side, aside from purchasing S&P 500 type index funds and waiting? When I purchase index funds, it's not to generate extra liquid cash on the side. I don't invest nearly enough to be able to purchase an index fund and earn substantial dividends. I don't want to get into any specific strategies because I'm not in the business of making investment recommendations, and I don't want to start. Furthermore, I don't think explicit investment recommendations are welcome here (unless it's describing why something is a bad idea), and I agree with that policy. I will make a couple of points, however. Understand your goals. Are you investing for retirement or a shorter horizon, e.g. some side income?
No, Mark is right, if you place a market order there will always be someone to buy or sell at the market price.  Only if you place a limit order on the price can it not sell or be bought.  Just research on your computer and you will find your answer.  You must be specify about open order or limit order when asking.
You would generally have to pay interest for everyday you hold the position overnight.  If you never close the position and the stock price goes to zero, you will be closed out and credited with your profit. If you never close the position and the stock price keeps going up and up, your potential loss is an unlimited amount of money.  Of course your broker may close you out early for a number of reasons, particularly if your loss goes above the amount of capital you have in your trading account.
How much time does the automated system wait to increment the price, the frequency of the price change and by what percentage to increment etc. So I think the answer to all these questions is that the automated system does none of these things. It merely publishes information about (a) the last trade price, (b) the price that is currently the lowest price at which anyone has expressed a willingness to sell, and (c) the price that is currently the highest price at which anyone has expressed a willingness to buy. ::edit:: Oh, I forgot to answer your primary question. Can we estimate the impact of a large buy order on the share price? Not only can we estimate the impact, but we can know it explicitly. Because the exchange publishes information on all the orders it knows about, anyone tracking that information can deduce that (in this example) there were exactly 100,000 shares waiting to be purchased at $15.00. So if a ""large buy order"" of 1M shares comes in at $15.00, then we know that all of the people waiting to sell at $15.00 will be matched, and the new lowest ask price will be $15.01 (or whatever was the next lowest sell price that the exchange had previously published)."
Here's a good link that can answer your question: How to take delivery of a futures contract The relevant part states: Prior to delivery day, they inform customers who have open long positions that they must either close out the position or prepare to take delivery and pay the full value of the underlying contract. By the same token traders with short positions are informed that they must close out their trades or prepare to deliver the underlying commodity. In this case, they must have the required quantity and quality of the deliverable commodity on hand.   On the few occasions that a buyer accepts delivery against his futures contract, he is usually not given the underlying commodity itself (except in the case of financials), but rather a receipt entitling him to fetch the hogs, wheat, or corn from warehouses or distribution points. I hope this helps. Good luck!
Well they do have incentive, the more volume you trade the more they make in commission. The shop is mostly daytrading oriented but you can do whatever you want. From what I gather, alot of their revenue comes in the form of training programs (although they offer one for free when you sign up, mostly in equities) which are completely optional. Also, they're willing to sponsor me for my 7, which is good. I mean this is a super risky career move but you roll the dice when you enter prop trading, in more ways than one.
The program placed orders in 25-millisecond bursts involving about 500 stocks, according to Nanex, a market data firm. The algorithm never executed a single trade, and it abruptly ended at about 10:30 a.m. ET Friday.  So it changed its mind every single time?  That's either a bug or it's front running.  I think it's front running no matter how you look at it.    If I ran the SEC, I'd put in place a rule that says all orders must stand for 2 seconds before they can be cancelled.  That's enough time for humans to react in the market.  This 25 ms for 500 stocks is nonsense.  That's just front running to defraud real investors and make money on very small differences in price millions of times a day.  It distorts the markets and does no good for anyone except the brokerage that is running the scam.
There are classes of 'traders' who close their positions out every evening, not just on fridays.  But their are other types of businesses who trade shortly before or nearly right at market close with both buys and sells  There are lots of theories as to how the market behaves at various times of day, days of the week, months of the year.  There are some few patterns that can emerge but in general they don't provide a lot of 'lift' above pure random chance, enough so that if you 'bet' on one of these your chances of being wrong are only very slightly different from being right, enough so that it's not really fair to call any of them a 'sure thing'.  And since these events are often fairly widely spaced, it's difficult to play them often enough to get the 'law of large numbers' on your side (as opposed to say card-counting at a blackjack table) which basically makes betting on them not much different from gambling
The best thing to do is not worry about what time is best to buy but put in a conditional order before the market opens. If your conditions are met during the trading day your order will go through and you will buy the shares. This keeps your emotions out of your trading and will stop you from either chasing the market or buying when you consider the wrong time. As you have already done your analysis and made your decision before market open, thus you should place your conditional orders and stop losses before market opens as well.
As far as trading is concerned, these forward curves are the price at which you can speculate on the future value of the commodity.  Basically, if you want to speculate on gold, you can either buy the physical and store it somewhere (which may have significant costs) or you can buy futures (ETFs typically hold futures or hold physical and store it for you).  If you buy futures, you will have to roll your position every month, meaning you sell the current month's futures and buy the next month's.  However, these may not be trading at the same price, so each time you roll your position, you face a risk.  If you know you want to hold gold for exactly 1 year, then you can buy a 1-year future, which in this case according to your graph will cost you about $10 more than buying the front month.  The forward curve (or sometimes called the futures term structure) represents the prices at which gold can be bought or sold at various points in the future.
"Nobody has mentioned the futures market yet. Although the stock market closes at 4pm, the futures market continues trading 24 hours a day and 5.5 days a week. Amongst the products that trade in the future market are stock index futures.  That includes the Dow Jones, the S&P 500. These are weighted averages of stocks and their sectors. You would think that the price of the underlying stock dictates the price of the average, but in this day and age, the derivative actually changes the value of the underlying stock due to a very complex combination of hedging practices. (this isn't meant to be vague and mysterious, it is ""delta hedging"") So normal market fluctuations coupled with macroeconomic events affect the futures market, which can ripple down to individual stocks. Very popular stocks with large market caps will most certainly be affected by futures market trading. But it is also worth mentioning that futures can function completely independently of a ""spot"" price. This is where things start to get complicated and long winded. The futures market factor is worth mentioning because it extends even outside of the aftermarket and pre-market hours of stock trading."
This all happens at once and quickly. Not in order.  So the HFT floods the exchange with orders. This is independent of anything. They would be doing this no matter what. Simply in anticipation of finding someone who will want what they're trying to buy.   They then notice someone wants what they have a buy order for. They, at the same time, cancel all orders that don't fit this criteria. At the same time, they're testing this guy to see what his price is. So while they're testing this guy they're cancelling all orders that are above his strike price for that stock. They let the right order go through, for a lower price. If they can't get a lower price, they just forget it. However, they probably can because they were in line first. They're buying before this guy and AFTER they know what he wants to pay.    Then, they sell it to him.
"Basically, your question boils down to this: Where and how do I squeeze the stock market so that within time period X, it will make me Y dollars. (Where I'm emotionally attached to the Y figure because I recently lost it, and X is ""as soon as possible"".) To make money on the stock market (in a quasi-guaranteed way), you have to adjust X and Y so that they are realistic. For instance, let X be twenty-five years, and Y be ""7% annual return"". Small values of X are risky, unless X is on the order of milliseconds and you have a computer program working for you. To mitigate some of the risk of short term trading, you have to treat trading seriously and study like mad: study the stock market in general, and not only that, but carefully research the companies whose stocks you are buying. Work actively to discover stocks which are under-valued relative to the performance of their corporation, and which might correct upward relative to the performance of similar stocks. Always have an exit strategy for every position and stick to it. Use instruments like ""trailing stops"": automatic tracking which follows a price in one direction, and then produces an order to close the position when the price reverses by a certain amount."
the financial information is generally filed via SEDAR (Canada) or SEC (US) before the conference call with the investment community.  This can take before either before the market opens or after the market closes.  The information is generally distribute to the various newswire service and company website at the same time the filing is made with SEDAR/SEC.
By this token, most fx trading is necessarily short-term 'day-trading', which by itself carries inherent risk. 2) Fx markets are insanely efficient (I will lightly state that this is my opinion, but one that I am not alone in holding firmly). This means that public information about a currency [ie: economic news, political news, etc.] is nearly immediately acted upon by many, many people, so that the revised fx price of that currency will quickly adjust. The more efficient a market is, the harder it is to 'time a trade'. As an example, if you see on a news feed that the head of a central bank authority made an announcement about interest rates in that country [a common driver of fx prices], you have only moments to make a trade before the large institutional investors already factor it into their bid/ask prices. Keep in mind that the large fx players are dealing with millions and billions of dollars; markets can move very quickly because of this. Note that some currencies trade more frequently than others. The main currency 'pairs' are typically between USD and / or other G10 country-currencies [JPY, EUR, etc.]. As you get into currencies of smaller countries, trading of those currencies happens less frequently. This means that there may be some additional time before public information is 'priced in' to the market value of that currency, making that currency 'less efficient'. On the flip side, if something is infrequently traded, pricing can be more volatile, as a few relatively smaller trades can have a big impact on the market. 3) Uncertainty of political news. If you make an fx trade based on what you believe will happen after an expected political event, you are taking risk that the event actually happens. Politics and world events can be very hard to predict, and there is a high element of chance involved [see recent 'expected' election results across the world for evidence of this]. For something like the stock market, a particular industry may get hit every once in a while with unexpected news, but the fx market is inherently tied to politics in a way that may impact exchange rates multiple times a day. 4) Leveraging. It is very common for fx traders to borrow money to invest in fx.
