How to access indicator in a strategy

[MrScrillz]

I have a strategy where I would like to use many indicators.

If I take for example the ADX indicator, and instantiate an object of this type in the strategy's Initialize method and I also set CalculateOnBarClose = true; in the strategy's initialize method, then how am I able to access the value of the ADX indicator in the OnBarUpdate method?

I notice in another thread:

user koganam discusses having a variable as type of a class, and being able to access that variable (PricePoint in his example) directly through the instantiated object (standard object oriented programming), but the problem that I see here, is no variable in ADX to access the value of the indicator.

MrScrillz,

To access ADX in a strategy you can just call its value:
double myADXValue = ADX(14)[0];

You can create your own ADX variable as well if you want. Best place to declare is variables region and then instantiate in OnStartup().
Variables:
private ADX myADX;

OnStartup:
myADX = ADX(14);

Access in OnBarUpdate()
double myADXValue = myADX[0];
