Among the many types of technical analysis available to forex traders, the single most useful and popular are probably candlestick charts. These were originally developed in Japan during the 18th century by a prominent commodity trader who used them to chart the fluctuations in the price of rice. For this reason they are often known as Japanese candlestick charts, and many of the patterns that they form have Japanese names.
Simple line graphs plotting the price of a commodity at regular intervals in time had been used for centuries, but traders were in need of something that could plot more variables within a two dimensional graph. The bar chart showing the opening, high, low and closing prices of a commodity was useful and helped traders to predict future price movements in a more reliable way than line charts, but candlestick charts were even better.
They were introduced to the American stock market and from there to the worldwide financial markets by Charles Dow at the beginning of the 20th century. Dow was the founder of the Wall Street Journal and co-founder of the Dow Jones company.
Candlestick Formation
The chart is made up of a series of 'candlesticks' which typically have a chunky body with vertical lines stretching up from the top (the upper shadow or wick) and bottom (the lower shadow or wick). The different points measure the differential in prices over a certain period of time, which might be 5 minutes, 15 minutes or longer.
The top of the wick is the highest point reached during the time period and the lowest point of the lower wick is the low. The top and bottom of the body are the opening and closing prices. If price rose during the period the body will be white (or green or blue if colored). The bottom of the body marks the opening price and its top marks the close. If the price fell during the period the prices are the other way around and to show this at a glance the body will be black (or red if colored).
How To Use Candlestick Charts In Forex Trading
A chart showing 5 or 15 minute candles over a period of several hours can provide the forex trader with many patterns on which he can base a system for determining when a trend is developing. For example, when the candle body is white or green and higher than the preceding candles, it indicates that buyers are very bullish. When it is black or red and lower than the preceding candles, it indicates that buyers are very bearish.
Being able to see these implications at a glance is vital in the fast moving forex markets where trading decisions often need to be made in a split second. So candlestick charts are one of the most useful visual aids for any forex trader.
