Get plot value through reflection

March 3rd, 2015, 06:32 AM

I am able to get the value of middle band of Bollinger with the below code.

Code

double value = Bollinger(2,14).Values[1][0];

How can I do it with Reflection? Below is the code I have tried so far.

Code

Type[] dataTypes = null;
MethodInfo methodInfo = null;
object[] params = new object[2];

// Some code to get data types of method to "dataTypes" (System.Double,System.Int32)
// Some code to get parameters for the method to "params" (2,14)
// Some code to get information to "methodInfo" (Bollinger(2,14))

IDataSeries dataSeries = (IDataSeries)methodInfo.Invoke(this, params);
double value = dataSeries[0];

When I execute the above statement , I could get the value(for example,1650.00) in the variable "value". The issue is, I could not specify the band ,ie, Upper or Middle or Lower. I tried the below code.

Code

double value = dataSeries.Values[1][0];

but didn't work and throws error. Is there a way out?

Thanks in advance,

What do you need it for, I mean what is the purpose of the whole exercise?

I can select a set of indicators from a list, can select the plot for each indicator and need to get each indicator's plot value at runtime.

I have used an enum for the list of indicators and then attributed the selected indicators to an IDataSeries object in OnStartUp. An example would be the SuperTrendU11, which works with 29 different moving averages. It can be downloaded here:

Is that the solution you look for, or do you try to instantiate indicators dynamically?

PS: I just saw that you cannot download files, as you are not an elite member. Please send me a private message with your e-mail and I will send you the indicator, so that you can check it.

Yes. I instantiate the indicators dynamically at runtime in a loop and store them in a List<IDataSeries>.

But do you want to select the indicators from a dropdown list, or would you prefer instantiating them by using a string?

I have sent you the SuperTrendU11, so you can check whether that solution would work for you.
