ohlc chart การใช้

In technical analysis OHLC charts are often combined with charts of other types such as line charts ( showing moving average ), column charts ( trading volume ), and range areas ( Bollinger Bands ).
An "'open-high-low-close chart "'( also "'OHLC chart "') is a type of chart typically used to illustrate movements in the price of a financial instrument over time.
A simple variant on the OHLC chart is the HLC "'high-low-close chart "'that identifies the range of the time unit's price action ( high-low ) and the end result of the time unit's price action ( the close ).
