WHAT IS CANDLE STICK CHART?
The candlestick techniques we use today originated in the style of technical charting used by the Japanese for over 100 years before the West developed the bar and point-and-figure analysis systems. In the 1700s, a Japanese man named Homma, a trader in the futures market, discovered that, although there was a link between price and the supply and demand of rice, the markets were strongly influenced by the emotions of traders.
HOW TO READ CANDLESTICK CHART?
In order to create a candlestick chart, you must have a data set that contains open, high, low and close values for each time period you want to display. The hollow or filled portion of the candlestick is called “the body” (also referred to as “the real body”). The long thin lines above and below the body represent the high/low range and are called “shadows” (also referred to as “wicks” and “tails”). The high is marked by the top of the upper shadow and the low by the bottom of the lower shadow.
