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.
