using external indicators

[futurenets]

this appears to work ...

private ATR myATR;

private double myVar;

OnStartUp()
myATR = ATR(Closes[0],20);

OnBarUpdate()
myVar = myATR[0];

but is there a discussion on other approaches and what's the most efficient?

[NinjaTrader_Bertrand]

futurenets, correct this is a workable and efficient approach using indicator instances variables.

[futurenets]

and this also?

private DataSeries myATR;

Initialize()
myATR = new DataSeries(this);

OnBarUpdate()
myATR.Set(ATR(Closes[0],20);

I'm not sure why you would want to do that, since the ATR already directly returns a series to work with, just like any other indicator method.

ok thanks I guess that's what I was trying to ask.

[futurenets]

trying to implement this but not working so not quite there yet.

I'll provide more detail if required but meanwhile ... HL2 is an indicator that returns (H+L)/2 and
works fine on its own but when try and use it as follows it returns closing price only:

private HL2 MI;

OnStartUp()
MI = HL2();

OnBarUpdate()
Print(MI.PlotHL2[0]);

if the error is not obvious then I'll provide more code.

are there any guidelines or potential conflicts that I need to be aware of?

Ignore this post. See PatrickH's reply.
Thanks.

Hello futurenets,

Thank you for your response.

There should be no issue in the way you are assigning and calling the value. Can you provide further information on the HL2, such as the code?
