How do day-traders or frequent traders handle their taxes?
"There are two ways to handle this. The first is that the better brokers, such as Charles Schwab, will produce summaries of your gains and losses (using historical cost information), as well as your trades, on a monthly and annual basis. These summaries are ""ready made"" for the IRS. More brokers will provide these summaries come 2011. The second is that if you are a ""frequent trader"" (see IRS rulings for what constitutes one), then they'll allow you to use the net worth method of accounting. That is, you take the account balance at the end of the year, subtract the beginning balance, adjust the value up for withdrawals and down for infusions, and the summary is your gain or loss. A third way is to do all your trading in say, an IRA, which is taxed on distribution, not on stock sales." Starting of 2011, your broker has to keep track of all the transactions and the cost basis, and it will be reported on your 1099-B. Also, some brokers allow downloading the data directly to your tax software or to excel charts (I use E*Trade, and last year TurboTax downloaded all the transaction directly from them). You need to track every buy and sell to track your gains, or more likely, losses. Yes, you report each and every transactions. Pages of schedule D.
"How often do investors really lose money? All the time. And it's almost always reason number 1. Let's start with the beginner investor, the person most likely to make some real losses and feel they've ""learned"" that investing is no better than Vegas. This person typically gets into it because they've been given a hot stock tip, or because they've received a windfall, decided to give this investing lark a try, and bought stock in half a dozen companies whose names they know from their everyday lives (""I own a bit of Google! How cool is that?""). These are people who don't understand the cyclic nature of the market (bear gives way to bull gives way to bear, and on and on), and so when they suddenly see that what was $1000 is now $900 they panic and sell everything. Especially as all the pundits are declaring the end of the world (they always do). Until the moment they sold, they only had paper losses. But they crystallised those losses, made them real, and ended at a loss. Then there's the trend-follower. These are people who don't necessarily hit a bear market, or even a downturn, in their early days, but never really try to learn how the market works in any real sense. They jump into every hot stock, then panic and sell out of anything that starts to go the wrong way. Both of these reactive behaviours seem reasonable in the moment (""It's gone up 15% in the past week? Buy buy buy!"" and ""I've lost 10% this month on that thing? Get rid of it before I lose any more!""), but they work out over time to lots of buying high and selling low, the very opposite of what you want to do. Then there's the day-trader. These are people who sit in their home office, buying and selling all day to try and make lots of little gains that add up to a lot. The reason these people don't do well in the long run is slightly different to the other examples. First, fees. Yes, most platforms offer a discount for ""frequent traders"", but it still ain't free. Second, they're peewees playing in the big leagues. Of course there are exceptions who make out like bandits, but day traders are playing a different game than the people I'd call investors. That game, unlike buy-and-hold investing, is much more like gambling, and day-traders are the enthusiastic amateurs sitting down at a table with professional poker players – institutional investors and the computers and research departments that work for them. Even buy-and-hold investors, even the more sophisticated ones, can easily realise losses on a given stock. You say you should just hold on to a stock until it goes back up, but if it goes low enough, it could take a decade or more to even just break even again. More savvy stock-pickers will have a system worked out, something like ""ok, if it gets down to 90% of what I bought it for, I cut my losses and sell."" This is actually a sensible precaution, because defining hard rules like that helps​ you eliminate emotion from your investing, which is incredibly important if you want to avoid becoming the trend-follower above. It's still a loss, but it's a calculated one, and hopefully over time the exception rather than the rule. There are probably as many other ways to lose money as there are people investing, but I think I've given you a taste. The key to avoiding such things is understanding the psychology of investing, and defining the rules that you'll follow no matter what (as in that last example). Or just go learn about index investing. That's what I did." &gt; It will have minimal effects on buy &amp; hold traders since they typically research for a long time, then buy &amp; hold stock for many months.  This is the part I never understand. If a short term tax doesn't affect buy &amp; hold traders, when why would HFT affect buy &amp; hold traders? "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. As I said, I won't get into this because while it's a nice debate for small traders, at large trading firms, they don't care; they want to make profit, and any strategy that can be vetted, whether it's fundamental, technical, or astrological, will be vetted.  I want to add more information to my answer to clear up some of the misconceptions in the comments, including those talking about biased studies and a lack of evidence for or against technical analysis (and candlestick charts; I'll explore this relationship further down).  It's important to keep in mind that charting methods, including candlestick charts, are visually subjective ways of representing data, and that any interpretations drawn from such charts should, ideally, represent objective technical indicators. A charting method is only as good as the indicators it's used to represent. Therefore, an analysis of the underlying indicators provides a suitable analysis for the visual medium in which they're presented.  One important study that evaluates several of these indicators is Foundations of Technical Analysis: Computational Algorithms, Statistical Inference, and Empirical Implementation by Lo, Mamaysky, and Wang. Lest anyone accuse its authors of bias, I should point out that not only is it published by the National Bureau of Economic Research (a highly reputable organization within economics and finance), but also that the majority of its authors come from MIT's Sloan school, which holds a reputation second to none. This study finds that several technical indicators, e.g. head-and-shoulder, double-bottom, and various rectangle techniques, do provide marginal value. They also find that although  human judgment is still superior to most computational algorithms in the area of visual pattern recognition, ... technical analysis can be improved by using automated algorithms Since this paper was published in 2000, computing power and statistical analysis have gained significant ground against human ability to identify and exploit for visual pattern detection like candlestick charts.  Second, I suggest you look into David Aaronson's book, Evidence-Based Technical Analysis: Applying the Scientific Method and Statistical Inference to Trading Signals. He finds similar results to the Lo, et. al. paper, in that some technical indicators do add value to the investment process, but those that do are those that can be represented mathematically and thus programmed directly into trading algorithms (thus bypassing visual tools like candlestick charts).  He describes how studies, including Lo, et al., have found that head and shoulders patterns are worse than random, i.e. you would earn higher returns if you simply traded at random. That point is worth than repeating. If a day-trader is using a candlestick chart and using head-and-shoulders patterns as part of their toolkit, he's rolling the dice when he uses that pattern and returns that come from its application come from chance. This reminds me of that old story about a company that sends out pamphlets predicting the results of sports games, complete with ""strategies"" and ""data"" to back up the predictions. The company sends out several versions of the pamphlet every game, each predicting a different winner. Given a large enough sample size, by the end of the season, there are a few people who have received a pamphlet that accurately predicted the winner for every game and they're convinced the system is perfect. The others weren't so lucky, however. Relying on candlestick charts and TA patterns that are relics from the pre-computerized era is reassuring to some traders and gives them a sense of control and ""beating the market,"" but how long will chance remain on your side? This is why I maintain that visual tools like candlestick charts are a slowly dying medium. They certainly still add value to some trading firms, which is why Bloomberg terminals still ship with this functionality built in, but as more and more research shows, automated algorithms and statistical indicators can provide more value. It's also important to think about whether the majority of the value added by visual tools like candlestick charts comes in the form of profit or a sense of security to traders who learned the field using them over the past few decades.  Finally, it's extremely important to realize that the actions of retail investors in the equities market cannot begin to represent the behaviors of the market as a whole. In the equities markets alone, trading firms and institutional investors dwarf retail investors, and the difference in scale is even more vastly pronounced in derivatives and currency markets. The fact that some retail investors use candlestick charts and the technical indicators they (hope) underlie them provides nothing but minor anecdotal evidence as to their effectiveness." "If you're going to be a day trader, you really need to know your stuff.  It's risky, to say the least. One of the most important elements to being successful is having access to very fast data streams so that you can make moves quickly as trends stat to develop in the markets.  If you're planning on doing this using consumer-grade sites like eTrade, that's not a good idea.  The web systems of many of the retail brokerage firms are not good enough to give you data fast enough for you to make good, timely decisions or to be able to execute trades way that day traders do in order to make their money.  Many of those guys are living on very thin margins, sometimes just a few cents of movement one way or the other, so they make up for it with a large volume of trades. One of the reasons you were told you need a big chunk of money to day trade is that some firms will rent you out a ""desk"" and computer access to day trade through their systems if you're really serious about it.  They will require you to put up at least a minimum amount of money for this privilege, and $25k may not be too far out of the ballpark. If you've never done day trading before, be careful.  It doesn't take much to get caught looking the wrong way on a trade that you can't get out of without losing your shirt unless you're willing to hold on to the stock, which could be longer than a day. Day trading sounds very simple and easy, but it isn't.  You need to learn about how it works (a good book to read to understand this market is ""Flash Boys"" by Michael Lewis, besides being very entertaining), because it is a space filled with very sophisticated, well-funded firms and individuals who spend huge sums of money to gain miniscule advantages in the markets. Be careful, whatever you do.  And don't play in day trading with your retirement money or any other money you can't afford to walk away from. I hope this helps. Good luck!" "You have a high risk tolerance? Then learn about exchange traded options, and futures. Or the variety of markets that governments have decided that people without high income are too stupid to invest in, not even kidding. It appears that a lot of this discussion about your risk profile and investing has centered around ""stocks"" and ""bonds"". The similarities being that they are assets issued by collections of humans (corporations), with risk profiles based on the collective decisions of those humans. That doesn't even scratch the surface of the different kinds of asset classes to invest in. Bonds? boring. Bond futures? craziness happening over there :) Also, there are potentially very favorable tax treatments for other asset classes. For instance, you mentioned your desire to hold an investment for over a year for tax reasons... well EVERY FUTURES TRADE gets that kind of tax treatment (partially), whether you hold it for one day or more, see the 60/40 rule. A rebuttal being that some of these asset classes should be left to professionals. Stocks are no different in that regards. Either educate yourself or stick with the managed 401k funds." If you have made $33k from winning trades and lost $30k from loosing trades your net gain for the year would be $3k, so obviously you would pay taxes only on the net $3k gains. Unless your investments are held within a special tax-free account, then every sale transaction is a taxable event, meaning a gain or loss (capital gain/loss or income gain/loss, depending on various circumstances) is calculated at that moment in time. Gains may also accrue on unrealized amounts at year-end, for specific items [in general in the US, gains do not accrue at year-end for most things]. Moving cash that you have received from selling investments, from your brokerage account to your checking account, has no impact from a tax perspective. "Long term: Assuming you sold stock ABC through a registered stock exchange, e.g., the Bombay Stock Exchange or the National Stock Exchange of India, and you paid the Securities Transaction Tax (STT), you don't owe any other taxes on the long term capital gain of INR 100. If you buy stock BCD afterwards, this doesn't affect the long term capital gains from the sale of stock ABC.  Short term: If you sell the BCD stock (or the ABC stock, or some combination therein) within one year of its purchase, you're required to pay short term capital gains on the net profit, in which case you pay the STT and the exchange fees and an additional flat rate of 15%.  The Income Tax Department of India has a publication titled ""How to Compute your Capital Gains,"" which goes into more detail about a variety of relevant situations."
