Definition of day trading
"The American ""Security Exchange  Commission"" has imposed a rule upon all stock trading accounts. This rule is ""Regulation-T"". This rule specifies that stock trading accounts must be permitted three days after the termination of a trade to settle the account. This is just fancy lingo to justify the guarantee that the funds are either transferred out of your account to another persons  (the person that made money), or the money flows into your account.  A ""Day Trader's"" account avoids the hassle because you're borrowing money from your broker to trade with and circumvent Reg-T.  It's technically not how long you hold the trade that determines if you're a day trader, or not. It's your accounts liquidity and your credit worthiness."
There are several reasons why this may happen and I will update as I get more information from you. Volumes on that stock look low (supposing that they are either in a factor between 1s and 1000s) so it could well be that there was no volume on that day. If no trades occur then open, high and low are meaningless as they are statistics based on trades that occur that day and no trades occur. Remember that there has to be volume to get a price. The stock may have been frozen by either the exchange or the company for the day. This could be for various reasons including to prevent some illegal activity. In that case no trades were made because the market for that stock was closed. Another possibility is that all trades that day were cancelled by the exchange. The exchange may cancel all trades if there is unusual, potentially fraudulent or other illegal activity on the stock. In this case the last price for that day existed but was rolled back by the exchange and never occurred. This is a rare situation. Although I can't find any holidays on that date it is possible that this is how your data provider marks market holidays. It would be valid to ignore the data in that case as being from a non-market day. I cannot tell if this is possible without knowing exchange information. There is a possibility that some data providers don't receive data for a day or that it gets corrupted. It may be worth checking another source to ensure the integrity of the data that you are receiving. Whichever reason is true, the data provider has made the close equal to the previous day's close as no price movements occurred. Strictly the closing price is the price of the last trade made for that day and so should be null (and open, high and low should be null too and not 0 otherwise the price change on day is very large!). Therefore, to keep integrity, you have a few choices: That is such a vague statement, I highly recommend disregarding it entirely, as it is impossible to know what they meant. Their goal is to convince you that index funds are the way to go, but depending on what they consider an 'active trader', they may be supporting their claim with irrelevant data Their definition of 'active trader' could mean any one or more of the following: 1) retail investor 2) day trader 3) mutual fund 4) professional investor 5) fund continuously changing its position 6) hedge fund. I will go through all of these. 1) Most retail traders lose money. There are many reasons for this. Some rely on technical strategies that are largely unproven. Some buy rumors on penny stocks in hopes of making a quick buck. Some follow scammers on twitter who sell newsletters full of bogus stock tips. Some cant get around the psychology of trading, and thus close out losing positions late and winning positions early (or never at all) [I myself use to do this!!]. I am certain 99% of retail traders cant beat the market, because most of them, to be frank, put less effort into deciding what to trade than in deciding what to have for lunch. Even though your pension funds presentation is correct with respect to retail traders, it is largely irrelevant as professionals managing your money should not fall into any of these traps. 2) I call day traders active traders, but its likely not what your pension fund was referring to. Day trading is an entirely different animal to long or medium term investing, and thus I also think the typical performance is irrelevant, as they are not going to manage your money like a day trader anyway. 3,4,5) So the important question becomes, do active funds lose 99% of the time compared to index funds. NO! No no no. According to the WSJ, actively managed funds outperformed passive funds in 2007, 2009, 2013, 2015. 2010 was basically a tie. So 5 out of 9 years. I dont have a calculator on me but I believe that is less than 99%!   Whats interesting is that this false belief that index funds are always better has become so pervasive that you can see active funds have huge outflows and passive have huge inflows. It is becoming a crowded trade. I will spare you the proverb about large crowds and small doors. Also, index funds are so heavily weighted towards a handful of stocks, that you end up becoming a stockpicker anyway. The S&P is almost indistinguishable from AAPL. Earlier this year, only 6 stocks were responsible for over 100% of gains in the NASDAQ index. Dont think FB has a good long term business model, or that Gilead and AMZN are a cheap buy? Well too bad if you bought QQQ, because those 3 stocks are your workhorses now. See here 6) That graphic is for mutual funds but your pension fund may have also been including hedge funds in their 99% figure. While many dont beat their own benchmark, its less than 99%. And there are reasons for it. Many have investors that are impatient. Fortress just had to close one of its funds, whose bets may actually pay off years from now, but too many people wanted their money out. Some hedge funds also have rules, eg long only, which can really limit your performance. While important to be aware of this, that placing your money with a hedge fund may not beat a benchmark, that does not automatically mean you should go with an index fund. So when are index funds useful? When you dont want to do any thinking. When you dont want to follow market news, at all. Then they are appropriate. Understood. Similar to how doctors who go through/pay for med school prevent me from practicing medicine to profit.   Unsure what you think the average bbg user is doing with the terminal, bud. It's definitely not day-trading, at least not in the way you the think. "You have already indicted in another question, titled Which risk did I take winning this much?, that you did not understand (1) Why a previous trade made you as much money as it did; nor (2) How much you could have lost if things went a different way. You were, in that other question, talking about taking short position, without understanding (apparently) that a short position can create losses exceeding the value of your initial investment. Can one make money doing day trading? Yes, an educated investor may be able to prudently invest in short term positions making knowledgeable judgments about risk, and still make money. Can you make money doing day trading? Well, maybe. You have in the past, in what you described in a previous post as ""winning"". So even in your own eyes, you were effectively gambling, and got lucky. Perhaps the more relevant questions you can ask yourself are: Can you lose money doing day trading? And, most importantly, Are you more likely to lose money day trading, or consistently make money by taking on reasonable and educated risks?" When I place an order with Scottrade I also have to specify if I am wanting to trade outside of normal hours. "....causes loses [sic] to others. Someone sells you a stock.  The seller receives cash.  You receive a stock certificate.  This doesn't imply a loss by either party especially if the seller sold the stock for more than his purchase price. A day trading robot can make money off of the price changes of a stock only if there are buyers and sellers of the stock at certain prices.  There are always two parties in any stock transaction: a buyer and a seller.  The day trading robot can make money off of an investment for 20 years and you could still make money if the investment goes up over the 20 years.  The day trading robot doesn't ""rob"" you of any profit." "Can you give me a rundown of what I'm seeing?  Is this basically a super zoomed in tracker of a current stock or something?  Where a stock fluctuates a few cents up/down on the day, and you just trade before it goes down, then trade as it goes up or what?  EDIT: Is this really live?  Can you say, ""Yes this is live narwalls""" Levarge in simple terms is how of your own money to how much of borrowed money.   So in 2008 Typical leverage ratios were Investment Banks 30:1 means that for every 1 Unit of Banks money [shareholders capital/ long term debts] there was 30 Units of borrowed money [from deposits/for other institutions/etc]. This is a very unstable situation as typically say you lent out 31 to someone else, half way through repayments, the depositors and other lends are asking you 30 back. You are sunk. Now lets say if you lent 31 to some one, but 30 was your moeny and 1 was from deposits/etc. Then you can anytime more easily pay back the 1 to the depositor. In day trading, usually one squares away the position the same day or within a short period. Hence say you want to buy something worth 1000 in the morning and are selling it say the same day. You are expecting the price to by 1005 and a gain 5. Now when you buy via your broker/trader, you may not be required to pay 1000. Normally one just needs to pay a margin money, typically 10% [varies from market to market, country to country]. So in the first case if you put 1000 and get by 5, you made a profit of 0.5%. However if you were to pay only 10 as margin money [rest 990 is assumed loan from your broker]. You sell at 1005, the broker deducts his 990, and you get 15. So technically on 10 you have made 5 more, ie 50% returns. So this is leveraging of 10:1. If say your broker allowed only 5% margin money, then you just need to pay 5 for the 1000 trade, get back 5. You have made a 100% profit, but the leveraging is 20:1.  Now lets say at this high leveraging when you are selling you get only 990. So you still owe the broker 5, if you can't pay-up and if lot of other such people can't pay-up, then the broker will also go bankrupt and there is a huge risk.  Hence although leveraging helps in quite a few cases, there is always an associated risk when things go wrong badly.
