ChartDirector 6.2 (.NET Edition)

Finance Chart (1)




This example demonstrate creating a full-featured finance chart, with HLOC, moving averages, Bollinger band, volume bars, RSI and Momentum indicators.

This example employs the FinanceChart library add-on to allow complex financial charts to be composed easily. In this example, the key steps are:

For simplicity and to allow this example to run without connecting to a real database, a RanTable object is used to simulate the data. RanTable is a ChartDirector utility class used for creating tables with random numbers.
