Read strategy parameters

[Stephan123]

Hi,

how does one obtain the values of
<mystrategy>.Parameters[index] ?
When I try it with Parameters[index].Value it's empty.
Parameters[index].Name works though.

What's wrong here?

Hi Stephan123, accesing the running strategy instance parameters is unfortunately not supported in NinjaScript.

if you want to edit the running strategy parameters, then my tool might be of help:

Is accessing the running strategy instance parameters also not possible
within OnTermination()?

I only want to read and print them to a file. No editing is neccessary.

i think a simple this.ToString() would be enough for your needs, else you could get the propertyinfo from the Type.

I already tried this.ToString() .
The problem: parameter values are separeted by commas.
If the parameters are double values they have commas as well and there is no way to
recognice the separation of the parameters.

using propertyinfo gives me all properties of the strategy class, if applied to the type of the strategy class. I didn't find a way to filter for
the strategy parameters only.

In that case, it looks like you will need to use the CultureInfo and IFormatProvider in the ToString() method.

I tried:

Print(this.ToString(CultureInfo.CreateSpecificCult ure("en-GB")));

It gives error CS0103.
it doesn't know CultureInfo in this context.
How should it be?

You can filter the strategy properties for the gridcategory attribute

This is what i do in my ninjatinymobiletrader

"this" is the class itself. CultureInfo is used on numbers.

yes split the same, use regex etc etc.

if you need to do more then you have to use the propertyinfo. as Andreas rightly said, filter the values as per required.

Still two questions:

1) When using this.ToString() I get a string such as
mystrategy(2,5,2,4,true)

Since the comma is both decimation and seperating sign
parameter values can't be directly obtained from the string.
Is there a solution to that?

2) I would like to define the strategy itself as an input parameter of a function.
I tried it with

testfunction(this) for calling the function within the strategy
and
public void testfuntion(object myclass)
for defining the function within UserDefinedMethods.

Now I wonder how to extract any information from the object myclass,
such as myclass.performance or typeof(myclass).
How must this be coded?

Thanks in advance, Stephan
