What types of charts are available? For studying the markets by reading stock charts, here are the four main chart types used:
1. Bar charts (HLC / OHLC) – This is the most widely used chart and the default used throughout the site here on StockTrader.com. It is constructed to show four pieces of information: opening price (optional), closing price, high of the day, and low of the day. Looking at each day’s history, a vertical line shows the day’s trading range with a horizontal line pointing left to mark the opening price and a horizontal line pointing right to mark the closing price.
2. Candlestick charts – This chart presents the same data as a bar chart, but in a slightly different format. The chart has two main parts. The first is the thin line, known as the “shadow,” which shows the price range from high to low. The wider area, known as the “real body,” measures the difference between the opening price and the closing price. If the close is higher than the open, the real body is white.
3. Line charts – A line chart measures only the closing price and connects each day’s close into a line. Many technicians believe closing price is the only point that matters. For them, a line chart may be the most appropriate study.
4. Point and figure charts – A point and figure chart is concerned only with price, not time or volume. The chart uses an "X" to mark increases in price and an "O" to mark lower prices. With this approach, it is easier to spot trends and reversals. However, since time is not used as an input, P&F charts offer little guidance on timing, e.g. how long it will take for profit objectives to be met.
Each chart type for performing technical analysis has its benefits. By exploring the options each approach provides, investors can determine which type best meets their needs for reading stock charts.
Below I have taken a stock chart of the NASDAQ Composite and labeled the main parts. Below the chart I will explain these parts and what they mean when it comes to reading a stock chart.
Volume is one of the most basic and beneficial concepts to understand when trading stocks. Volume is defined as, "the number of shares (or contracts) traded during a given period of time." This means each time a person sells or buys shares of a stock, that is considered volume.
Tallying volume is done by the market exchanges and reported via every major financial website. To hand tally volume, simply add the shares traded for each order on the fly (you can see orders real-time with any streaming last sale tool). For example:
Total volume is then 1,600 shares for this sequence. Again, volume increases regardless if it is a buy or sell order.
It is not uncommon for stocks to trade millions of shares per day. For example, the S&P 500 ETF (SPY) trades on average around 75 million shares per market session. This is literally Billions of dollars worth of stock changing hands every day the market is open. On the other hand, smaller company stocks, known as penny stocks, might trade only a few thousand shares in a given day.
By understanding what volume is and how it is tracked, we can use this knowledge to help us make better informed trading decisions. There are two key benefits to tracking volume:
Learning to identify volume trends and count accumulation or distribution day strings on a stock chart does take practice. But, when applied correctly it is can give the investor a huge advantage in obtaining profits. Let's take a look at both.
To understand what an accumulation day is, it is important to look at the basic meaning of the actual word. Accumulation is based off of, "accumulate", which means to, "gather together or acquire an increasing number or quantity of". You accumulate a lot of things in life: wealth, strength, friends, etc. In the stock market, accumulation is used to describe the accumulation of shares by traders. The more people that buy, the more shares that are then purchased, which means more shares are accumulated. Make sense?
Things get easier when you add the word "day" into the picture. It is exactly as it sounds: an accumulation day is when the stock closes (finishes the day) higher on volume (or the amount of shares traded) that is also greater than the day prior. So, if stock XYZ closed yesterday at $13.50 a share with a total of 100,000 shares traded, and today closes as $14 a share with 300,000 shares traded, then we can say it was an accumulation day overall.
Accumulation days are very positive events, because they signal underlying strength due to the fact that institutions are accumulating shares and pushing the stock price higher. The more buying investors do, the more accumulating that is going on, and thus more a stock price will rise.
One final important concept to understand when identifying accumulation days on a stock chart is to look for days where volume was above the 60-day average. Low volume days have little meaning, because it means few institutions were involved. Personally, I ignore them. Here's a recent stock chart of Microsoft (MSFT) to help us out.
Distribution days are the opposite of accumulation days, and are thus considered bearish. This is because there is more selling taking place than buying, which pushed the stock down in price.
For a day to be considered a distribution day, the stock not only has to end down (net $ change), but there also has to be more volume (total shares traded) than the day before. Remember too that, like accumulation days, the volume not only needs to be greater than the day prior, but also greater than the 60-day average.
In summary, when you think of distribution days, think of the word "distribute", or selling, or heck, the color red. With a distribution day, there is simply more net sellers than buyers. Here's examples using the same chart of Microsoft (MSFT).
Every investor should have a strong understanding of volume and its role in the stock market. Every stock gives key buy and sell signals which can be found by simply knowing how to interpret volume on stock charts. This quiz will test the basics.
1. Volume is simply the number of _______ traded in a given day.
2. In a Accumulation day, a stock closes the day _______ (up or down), whereas in a Distribution day, a stock ends the day ________ (up or down).
3. Interpreting volume is a form of fundamental or technical analysis?
4. To be considered an accumulation or distribution day, one requirement is that volume must be greater than _______?
5. Stock ABC on Monday traded a total of 150,000 shares and finished the day up. Then, on Tuesday, the stock traded a total of 180,000 shares and finished the day down. The 60 day average daily volume is 200,000 shares. What is Tuesday considered?
