Despite the fact that there are normally several chart types, the mostly used are line chart, the bar chart and the highly popular chart which is the candlestick chart. Charts and chart reading and understanding are essential for implementing and applying technical indicators.
A line chart is rarely put into use regularly a lot of now days. It was initially the essential chart used prior to the arrival of the personal pc. At that time, stock price information was documented by hand, considering that solely final prices had been recorded. The line chart was created joining the final prices.
With regard to a bar chart, the highest in addition to the very least prices within a prescribed span of time (minutes, hours, days, weeks, or months) can be linked with a vertical bar. The initial price might be displayed by way of a tick mark at the left side; the fnal price is represented simply by the tick mark at the right side. The bottom and the top of the vertical bar symbolize the cheapest in addition to highest prices involving the span, respectively. The bar chart is utilized mostly in Western technical analysis.
The beginnings of candlestick charts was in Japan several hundred years ago. It was not until 1990 that the world knew about it when it was introduced in his book Candlestick Charting Techniques (Nison, 1991).
Candlesticks basically outline price variations that occur during a specific time.the candlestick body display the price change that occurred between the market open and close during the given time span. The candle is shown white if the closing price is higher than the opening price, but shown dark when the closing price is lower than the opening price. Candlestick can be shown in a body or a body with short and long wicks. When it comes to Candlestick charts, the subject is huge and needs a separate study.
Looking at price movements of 100% and more it may be a good idea to make use of a logarithmic scaling on the vertical price axis of the chart. If you are employing a scale of five points on a linear scale, a price change from $15 to $30 comprises three divisions, whereas a price variation from $30 to $60 consists of six divisions. This means that the distance on the vertical axis from $30 to $60 is twice as large as the one from $15 to $30. On the other side, a price move from $15 to $30 or from $30 to $60 equates to the same 100% price increase. A price moving from $15 to $30 or from $100 to $115 is the same comparable on a linear scale. Evidently, this really does not allow for a good graphic understanding associated with exactly what the price change definitely offers.
When stock price moves from $15 to $30 , this price movement is measured as 100% price move but when the price moves from $100 to $115 , only 15%. In order to have the same distance on the vertical axis display the same percent increase in the price, you will need to employ the logarithmic scale. So when using the logarithmic scale, you can a price increase of 100% when the price move from $30 to $60 similar to a price increase from $15 to $30. So looking at the chart will give more meaningful visual representation.
The moment there are sizable price movements, using a linear scale will constitute a disadvantage. It is basically not possible to sketch a linear scale underneath a upside trend or possibly a downside-moving trend. However, the majority of people use the linear which is acceptable provided that the move is within a very small price range. Logarithmic scale is more important when it comes to long-term time ranges such as weekly and monthly charts, mainly because the price changes are more noticeable. The best solution to this situation is to apply logarithmic scales of price movement always.
