One of the first things you should learn before you can get started in forex is read charts, and here are the ones that are commonly used:
- Line chart
- Bar chart
- Candlestick chart
Line Charts
As the name implies, these are simple charts consisting of a line drawn across the chart as from one closing price to the another. When these plotted points are connected together with a line, we can see the general trend of a currency pair, euro versus US dollar for instance, over a time period.
This is an example of a line chart:

Bar Charts
A bar chart, just like the line chart also reveals closing prices, however, it also allows you to see more than that, it shows the opening prices, the highs as well as the lows. Take a look at the vertical bar. The bottom pertains to the lowest traded price falling within that period of time, while the topmost portion of the bar tells you the highest price paid during that time period. All in all what is indicated by vertical bar is the trading range of the currency pair, EUR-USD for example. Do you see a horizontal hash on the bar’s left side? This indicates the opening price. The other side of the bar - the right side - indicates the closing price.

Remember that when the word bar is used, it pertains to a particular data on a chart. A single bar represents a time segment that can be an hour, a day or a week. When you encounter something like the bar going forward, it usually references a particular time frame, and you should pay attention as to what time frame is being referenced by it.
What is OHLC? This another name for the bar chart which stands for Open, High, Low, and Close for a specific currency.
Open indicates the opening price and indicated by that tiny line that runs across the left side. High, as the term implies, is at the top of the upright line, which indicates the highest price within that time frame. Low can be found at the bottom of the vertical line, and as the name implies indicate the lowest price paid within that period of time. Close is that little line running horizontally, which simplyt means the currency’s closing price.
Candlestick Charts
Candlestick charts have the same use as the bar chart, however it looks more pleasing to the eye, and is best suited for the beginner because it also serves as a visual aid.
Candlestick bars also indicate OHLC with some slight differences. The large block that you see in the middle pertains to the opening and closing range of prices. If the middle block has been shaded, colored, or filled it simply means that the currency closed lower than the opening price.

If you like candlestick charts, you are not confined to the use of traditional “colors” like black and white. You can substitute other colors for shading the middle blocks if you prefer.
Remember your preference for candlestick charts is purely esthetic, since in reality it is no better than an OHLC bar, which provides exactly the same information as the candlestick bar.
