The broad part of the candlestick line in Exhibit 1 is called the real body. The real body represents the range between the session's open and close. If the close of the session is above the open then the real body is white. If the real body is black the close of the session is lower than the open.
The thin lines above and below the real body are the shadows. These are the session's price extremes. The shadow above the real body is called the upper shadow and the peak of the upper shadow is the high of the session. The shadow under the real body is the lower shadow and the bottom of the lower shadow is the session's low.
Candle lines can be drawn for all time-frames, from intra-day to monthly charts. For example, a 60-minute candle line uses the open, high, low and close of that 60-minute period; for a daily chart it would be the open, high, low and close for the day. On a weekly chart the candle would be based on Monday's open, the high and low of the week and Friday's close.
Notice that the candles to the right have no real bodies. These are examples of doji (pronounced doe-gee). A doji is a candle in which the opening and close are the same. Doji represent a market that is in balance between the forces of supply and demand.
While the candlestick line uses the same data as a bar chart, the colour of the candlestick's real body and the length of the candle line's real body and shadows convey an instant x-ray into who's winning the battle between the bulls and the bears.
For instance, when the real body is black, that means the stock closed below its opening price. This gives you an instant picture of a positive or negative close. Those of us who stare at charts for hours at a time find candlesticks are not only easy on the eyes, they convey strong visual signals sometimes missed on bar charts.
The logo of our firm, which is a spinning top, is “ Helping Clients Spot Market Turns Before the Competition ”. This is because one of the most powerful aspects of candle charts is that they will often provide reversal signals not available with traditional bar charting techniques. Let's take a look at this aspect with a “spinning top.”
As mentioned previously, one of the more powerful aspects of candle charts is the quick visual information they relay about the market's heath. For example, a small real body (white or black) indicates a period in which the bulls and bears are more in a tug of war. The Japanese have a nickname for small real bodies - “spinning tops” - because of their resemblance to the tops we had as children. Such small real bodies give a warning that the market's trend may be losing momentum. As the Japanese phrase it, the "market is losing its breath."
