Using stock charts
Using OHLC values
Creating a scenario stock chart
Adding overlays
Generating OHLC values
Stock charts provide the ability to view the Open, High, Low, and Close values (OHLC) for a scenario variable or DataView field such as stock price over set time intervals. The intervals may be small such as 5 seconds if being used for intra-day trading or larger for longer time periods such as hours, days, or weeks. The following illustration is from the Stock Chart tutorial sample.
In this example, the OHLC values are shown as a candlestick chart where each “stick” represents a 5 second interval. The stock chart supports others display formats such as OHLC, line, and bar.
1. Open the file tutorial-stock-chart.rtv by double-clicking Stock Chart on the tutorial main page.
2. Select the stock chart object and in the Object Properties panel, select the priceTraceType property and change its value to OHLC.
The data displayed is the same as that displayed in the previous illustration where priceTraceType was set to Candlestick. Only the presentation has changed.
Although named “stock chart” you are not limited to using it for stock data. You can chart Open, High, Low, and Close values for any scenario variable or DataView field. Other financial and non financial data can often benefit from being visualized as a stock chart.
Detailed reference information on stock charts is provided in Stock charts.
