Candlestick charts show the same information as a bar chart but in a graphical format that is more fun to look at. Candlestick charts indicate the high and low of the given time period just as bar charts do, with a vertical line. The top vertical line is called the upper shadow while the bottom vertical line is called the lower shadow; you might also see the upper and lower shadows referred to as “wicks”. The main difference lies in how candlestick charts display the opening and closing price. The large block in the middle of the candlestick indicates the range between the opening and closing price. Traditionally this block is called the “real body”.
Generally if the real body is filled in, or darker in color the currency closed lower than it opened, and if the real body is left unfilled, or usually a lighter color, the currency closed higher than it opened. For example, if the real body is white or another light color, the top of the real body likely indicates the close price and the bottom of the real body indicates the open price. If the real body is black or another dark color, the top of the real body likely indicates the open price and the bottom indicates the close price (I used the word “likely” since you can make the real body whatever color you want). This will all become clear with an illustration:
Now, here’s the same EURUSD daily chart that I showed you in line and bar form, as a candlestick chart. Note that I have made the candles black and white, you can pick whatever colors you want, just make sure they are friendly to your eye but also that they convey bullish and bearishness to you. Bullish candles are the white ones (close higher than open) and bearish candles are the black ones (close lower than open):
Candlestick charts are the most popular of all three major chart forms, and as such, they are the type you will see most often as you trade, and they are also the type I recommend you use when you learn and trade with price action strategies. I use candlestick charts in my Forex trading course, and I recommended all my members use them when posting up charts in the members’ forum, because their visual pleasantness and simplicity make it easier for everyone to learn from.
