How to use Indicators in Strategies

Hello folks,

hopefully this is the right section. I got the t2u.liberator.dll from here: http://indo-investasi.com/showthread.php/19205-REQ-john-maddog-doe-or-zeraw31-pls-educate-t2u-systems/page3

Working with the indicators in a chart works like a charm.

But how can I call these indicators from another indicator? I allready added the DLL as a reference.

Then I try to call it via NinjaTrader.Indicator.Indicator.METHODNAME.

But at this point, I will get a compiling error. There is no definition for this method.

In example:

base.Liberator_Momentum(5, 5, MA_1271Type2.EMA, 5, true, "a"); Throws me this error.

So, how can I call these indicators? Do I need the cs-files from the dll? Where do I have to put these?

Thanks in advance!

First, DLL's typically have "base", "this", etc. in them, but if you are coding a strategy (cs) you don't need to add this. You typically call something specific from the DLL, like a dataseries (for example).

I typically add a variable like this: private DllName VariableName;

Then in "initialize" I will define the variable (make sure you insert inputs in correct order): VariableName = Liberator_Momentum(5, 5, MA_1271Type2.EMA, 5, true, "a");

Then I will call the dataseries I want, for example: Values[0].Set(VariableName.DataseriesName[0]);

Assuming the dll has exposed them for you to call.

Tanks for reply!

How can I make clear, that I can userId functions from the DLL.

Decompiling and getting the cs Files is no Problem. But the following steps arent clear.

Tanks for replies till now!
