Open-High-Low-Close (OHLC) chart is popular as a visual aid for decision making in stock, foreign exchange, commodities, and options trading. In Origin, an OHLC chart is created using XYYYY columns, arranged in the following order: Date/Time (X axis positon), open price, high daily price, low daily price, closing price.
The vertical line component (the price bar) shows the daily price range (min to max) and the left/right ticks indicate the opening and closing prices, respectively. Origin's OHLC chart supports use of different colors to indicate an advancing price bar (today's close higher than yesterday's) or a declining price bar. You can customize different bars in Advancing/Declining Price tab.
