Price chart types
Bar charts
The most common type of chart showing price action. Each bar represents a period of time - a "period" as short as 1 minute or as long as several years. Over time, bar charts show distinct price patterns.
Candlestick charts
Instead of a simple bar, each candlestick shows the high, low, opening and closing price for that period of time it represents. Candlestick patterns provide greater visual detail as they develop.
Point & figure charts
Point & figure patterns resemble bar chart patterns, except Xs and Os are used to mark changes in price direction. Point & figure charts make no use of time scale to associate a certain day with a certain price action.
