| I just discovered your product tonight. Seems very nice. I have a few questions and hopefully someone can assist. All of my questions are related to the finance charting features for asp.net. 1) Is it possible to add additional custom technical indicators to the chart (that are not already in the product)? 2) Is it possible to draw trend lines using: - client side browser - server side 3) Is it possible to display only a portion of a stock's data, yet perform technical indicator calculation on a broader set of data? For example, I might only display 3 months of a stock's data, but I want to show the 200 day moving average. 4) Can the chart be setup so that individual values are displayed (perhaps in a different html element) when the user mouses over the chart? 5) If I wanted to display the charts on my site and also allow other sites to show them, what license would be appropriate? Kind regards, Travis | |

| Hi Travis, 1) Is it possible to add additional custom technical indicators to the chart (that are not already in the product)? Yes. A lot of customers have proprietary indicators in which the formulas are secret. Basically, after computing the indicators with your own code, you may use the FinanceChart.addLineIndicator, FinanceChart.addLineIndicator2, FinanceChart.addBarIndicator, FinanceChart.addLineIndicator2 or other methods to add them to the chart. 2) Is it possible to draw trend lines using: - client side browser - server side By "draw trend lines", do you mean to draw programmatically and automatically (some code computes the trend line and add it ot the chart) or interactively (the user uses the mouse to create a line, similar to using Windows Paint or Photoshop to draw a line)? You can always draw lines programmatically and automatically on the server side. For example, some of our customers developd algorithms that can automatically compute support and resistance lines, fibonacci retracements, etc., and ask ChartDirector to add them to the charts. If you are referring to a "Windows Paint" or "Photoshop" like user interface for the user to draw things, unluckily, ChartDirector does not have such an interface. You would need to develop them with your own code. For example, in the simplest case, you may let the customer clicks two points, and then pass them to ChartDirector to create a line. 3) Is it possible to display only a portion of a stock's data, yet perform technical indicator calculation on a broader set of data? For example, I might only display 3 months of a stock's data, but I want to show the 200 day moving average. Yes. If you want to display 90 days of data, but 200 days moving average, you may pass 290 days of data to ChartDirector (so that ChartDirector can compute the moving averages for the last 90 days), and ask ChartDirector to display just the last 90 days. 4) Can the chart be setup so that individual values are displayed (perhaps in a different html element) when the user mouses over the chart? Yes. See the "Finance Chart Track Line (Web)" sample code. 5) If I wanted to display the charts on my site and also allow other sites to show them, what license would be appropriate? For licensing issues, I will forward your enquiry to sales@advsofteng.net. Please expect a response within 12 hours. Hope this can help. Regards Peter Kwan | |
