Is there software to buy and sell stocks in real time on very small moves in price?
I'm answering in a perspective of an End-User within the United Kingdom. Most stockbrokers won't provide Real-time information without 'Level 2' access, however this comes free for most who trade over a certain threshold. If you're like me, who trade within their ISA Holding each year, you need to look elsewhere.  I personally use IG.com. They've recently began a stockbroking service, whereas this comes with realtime information etc with a paid account without any 'threshold'. Additionally, you may want to look into CFDs/Spreadbets as these, won't include the heavy 'fees' and tax liabilities that trading with stocks may bring. Note that the pros pay for extremely fast access and are literally fighting over nanoseconds to get every possible advantage. Your system won't come close to that by several orders of magnitude. Consider the implications for the kinds of automated trading you want to perform. (Pico was overstating it. Nano, at the processor level and in terms of which transaction is first into the buffers, is certainly true. A millisecond is a Long Time in this domain.)
What I know about small companies and companies who are not listed on the stock markets is this: If a small company has shares issued to different people either within an organization or outside the value of the shares is generally decided by the individual who wants to sell the share and the buyer who wants to buy it. Suppose my company issued 10 shares to you for your help in the organization. Now you need money and you want to sell it. You can offer it at any price you want to to the buyer. If the buyer accepts your offer thats the price you get. So the price of the share is determined by the price a buyer is willing to buy it at from you. Remember the Face value of the shares remains the same no matter what price you sell it for. Now annual profit distribution is again something called dividends. Suppose my company has 100 shares in total out of which I have given you 10. This means you are a 10% owner of the company and you will be entitled to 10% of the net profit the company makes. Now at the end of the year suppose my company makes a 12,000 USD net profit. Now a panel called board of directors which is appointed by share holders will decide on how much profit to keep within the company for future business and how much to distribute about share holders. Suppose they decide to keep 2000 and distribute 10,000 out of total profit. Since you own 10% shares of the company you get 1000. The softwares you are talking are accounting softwares. You can do everything with those softwares. After-all a company is only about profit and loss statements. "Not at all impossible. What you need is Fundamental Analysis and Relationship with your investment. If you are just buying shares - not sure you can have those. I will provide examples from my personal experience:  My mother has barely high school education. When she saw house and land prices in Bulgaria, she thought it's impossibly cheap. We lived on rent in Israel, our horrible apartment was worth $1M and it was horrible. We could never imagine buying it because we were middle class at best. My mother insisted that we all sell whatever we have and buy land and houses in Bulgaria. One house, for example, went from $20k to EUR150k between 2001 and 2007. But we knew Bulgaria, we knew how to buy, we knew lawyers, we knew builders.  The company I currently work for. When I joined, share prices were around 240 (2006). They are now (2015) at 1500. I didn't buy because I was repaying mortgage (at 5%). I am very sorry I didn't. Everybody knew 240 is not a real share price for our company - an established (+30 years) software company with piles of cash. We were not a hot startup, outsiders didn't invest. Many developers and finance people WHO WORK IN THE COMPANY made a fortune. Again: relationship, knowledge!  I bought a house in the UK in 2012 - everyone knew house prices were about to go up. I was lucky I had a friend who was a surveyor, he told me: ""buy now or lose money"". I bought a little house for 200k, it is now worth 260k. Not double, but pretty good money!  My point is: take your investment personally. Don't just dump money into something. Once you are an insider, your risk will be almost mitigated and you could buy where you see an opportunity and sell when you feel you are near the maximal real worth of your investment. It's not hard to analyse, it's hard to make a commitment." Using Fundamental and Technical Analysis together is actually a good idea for longer term trading of up to 6 months or longer.  The whole idea behind trading with Technical Analysis is to increase the probabilities of a trade going in the desired direction by using uncorrelated indicators that produce the same signal to buy or sell at the same time. For example, you might use a Moving Average (MA) as a buy signal when the price falls for a few days, hits the MA and then reverses and starts moving back up. If however, you also include a Stochastic Oscillator (SO) to indicate when the stock is oversold (under 20%), and if the price rebounds from the MA average at the same time as the Stochastic is crossing over in the oversold position, then this may be a higher probability trade. If you also only trade stocks that are Fundamentally healthy (as fundamentally good stocks are more likely to go up than fundamentally bad stocks) then this might increase the probabilities again. Then if you only buy when the market as a whole is moving up, then this will increase your chances again. A few weeks ago at a seminar, the presenter totalled the men in the room to be 76 and the women in the room to be 8. He then asked what will most likely be the next person to walk in the room - a man or a woman? The statistics are on the side of a wan walking in next. This is what we try to do with Technical Analysis, increase our chances when we take a trade. Of course a woman could be the next person to walk in the room, just like any trade can go against you, and this is why we use money management and risk management and take a small loss when a trade does go against you. Lets look at an example where you could incorporate FA with TA to increase your chances of profits:  Above is a candlestick chart of Select Harvest (SHV), the green line above the price is the perceived value, the pink line is the 40 day MA, the blue line is the EPS, and the white lines is the Stochastic Oscillator (above 80% being overbought and below 20% is oversold). From Feb 2015 to start of Aug 2015 the stock was uptrending, since then the price reversed and started to downtrend. The stock was determined to be fundamentally good early in 2015 with the perceived value gradually increasing and greater than the share price, and the EPS starting to increase regularly from mid April. Thus, as the stock is seen as fundamentally healthy any price reversal in the vicinity of the MA could be seen as a buy opportunity. In fact there where 2 such opportunities on 31st March and 11th June where price had reversed and rebounded off the MA whist the SO crossed over in or near the oversold area. The price did reverse and then rebounded off the MA again on 9th July, however the SO was not in or near the oversold area on this occasion, so not as high in probability terms. The price still rebounded and went up again, however another momentum indicator (not shown here) shows some bearish divergence in this case - so another reason to possibly keep away at this point in time. A good signal to get out of the trade, that is your stop loss has not already taken you out, is when the price breaks and closes below the MA line. This occurred on 7th August. So if we had bought on the first signal on 31st March for $7.41 and sold when the priced broke through the MA on 7th August for $11.76, we would have made a profit of approx. 59% in just over 4 months. If bought on the second signal on 11th June for $9.98 and again sold on 7th August for $11.76, we would have made about 18% in under 2 months. So the fundamentals, the Price (in relation to MA) and the SO where all lining up to provide two high probability trades. Of course you would need to incorporate you risk management (including stops) in case the price did not continue upwards after you bought. If the market is also moving up on the day of the signal this will further increase your chances.  Unless you day trade, which I would avoid, a good way to enter your trades after a signal is to enter a stop buy order after market close to buy if the price moves above the high of the signal day. That way if the market and the stock open and move lower during the day after the signal you avoid entering the trade altogether. This can be incorporated as part of your risk management and trading rules. After the price broke down through the MA we can see that a downtrend commenced which is still current today (in fact I just took a short trade on this stock yesterday). We can also see that the perceived value, whilst still above the price, has reached a peak and is currently moving downwards and the EPS after being flat for a few months has just moved down for the first time in 10 months. So maybe the fundamentals are starting to waver a bit on this stock. It may be a good stock to continue shorting into the future. So basically you can continue using Fundamental Analysis to select which stocks to buy, place them in a watch-list, and then use Technical Analysis to determine when these stocks are starting to uptrend and use a combination of uncorrelated indicators to produce higher probability signals for when to enter your trades. "The price of real estate reacts to both demand for property and the rate of inflation and rate of income growth. Mortgage rates generally move as treasury rates move. See this paragraph: As we mentioned, intermediate term bonds and long-term mortgages (more properly, Mortgage-Backed Securities, or MBS) compete for the same fixed-income investor dollar. Treasury issues are 100% guaranteed to be repaid, but mortgages are not; therefore mortgages carry more risk of default or early repayment, which could potentially disturb the return on the investment. Therefore, mortgage rates must be priced higher to compensate for that risk. But how much higher are mortgages priced? In a normal market, the average ""spread"" or markup above the 100% secured Treasury is about 170 basis points, or 1.7%. That markup -- the spread relationship -- widens and contracts with a range of market conditions, investor appetites and supply of available product -- as well as the presence of competing investment opportunities, like corporate bonds or domestic (or foreign) equity markets Source: What Moves Mortgage Rates? And when the stock market crashes, investors tend to run to bonds and treasuries, which causes prices to go up and treasury yields to drop. Theoretically, this would also cause mortgage rates to drop, although most mortgage rates have a base price below which they cannot fall. How easy is it to profit from recent stock market drops and at what frequency? Incredibly difficult. The issue with your strategy is that you cannot predict the bottom of the market (at least us mortals can't). Just take the month of August for example. Stocks fell something like 15%? After the first 5-10% drop, people felt that the bottom was there, so they rushed in, only to have the market fall even more.  How will you know when to invest? Even if the market falls by 50%, and there's a huge buying opportunity, and you increase the mortgage on your house, odds are your rates will increase because of the equity you take out. What if the market stays low for a very long time? Will you be able to maintain mortgage payments? Japan's stock bubble popped in the early 90's, and they've had two lost decade's now. Furthermore, there are issues of liquidity. What if you need more capital? Can you just sell a property or can you buy now property to draw equity against? What if the market is moving too fast for you to take advantage of. Don't ignore transaction costs and taxes either.  Overall, there are a lot of ways that your idea can go wrong, and not many ways it can go right." Investopedia has one and so does marketwatch    I've always used marketwatch, and I have a few current competitions going on if you want me to send the link    They recently remodeled the website so it works on mobile and not as well on desktop    Don't know anything about the investopedia one though I've looked into Thinkorswim; my father uses it. Although better than eTrade, it wasn't quite what I was looking for. Interactive Brokers is a name I had heard a long time ago but forgotten. Thank you for that, it seems to be just what I need. I've never heard of such a thing, but seems like if such a product existed it would be easily manipulated by the big trading firms - simply bet that trading volume will go up, then furiously buy and sell shares yourself to artificially drive up the volume. The fact that it would be so easily manipulated makes me think that no such product exists, but I could be wrong. You can't tell for sure.  If there was such a technique then everyone would use it and the price would instantly change to reflect the future price value. However, trade volume does say something.  If you have a lemonade stand and offer a large glass of ice cold lemonade for 1c on a hot summer day I'm pretty sure you'll have high trading volume.  If you offer it for $5000 the trading volume is going to be around zero. Since the supply of lemonade is presumably limited at some point dropping the price further isn't going to increase the number of transactions.   Trade volumes reflect to some degree the difference of valuations between buyers and sellers and the supply and demand.  It's another piece of information that you can try looking at and interpreting.  If you can be more successful at this than the majority of others on the market (not very likely) you may get a small edge.  I'm willing to bet that high frequency trading algorithms factor volume into their trading decisions among multiple other factors.
