EMA Slope Indicator NT8

[demo152160]

Good Morning all, I am contacting you to ask you support regarding one indicator that I am trying to develop.

I am writing a strategy and I do need an indicator who print the slope value of the Exponential Moving Average EMA.

I've tried to create this indicator the inputs are:

1) The length of the EMA to be used.
2)The starting point of a series to be evaluated

I've copied and modified this example from the NT help:

// Original
// Prints the slope of the 20 period simple moving average of the last 10 bars
*
Print(Slope(SMA(20), 10, 0));

// Mine
// Prints the slope of the EMALenght period Exponential moving average of the //SeriesStartingPoint bars


Print(Slope(EMA(EMALenght), SeriesStartingPoint, 0));


The Script is compiling but when I load it on the chart the indicator box it is Empty.
Could you please have a look to it if I've made any mistake when I created the indicator.

Here attached a copy of the indicator that I made.

Thank you in advance for your support.

Good Evening Alan and thank you for your reply.
I've done the modification requested here to follow the code of the indicator:

protected override void OnBarUpdate()
{
/// Prints the slope of the SeriesStartingPoint period Exoponential moving average of
///the last EMALenght bars
*
if (CurrentBar < 1)
return;


Print(Slope(EMA(EMALenght), SeriesStartingPoint, 0));

}

But is still not printing any line in the indicator's box, the chart set is 500 Bars which should be enough, this indicator it should be pretty easy to do maybe I've done some stupid mistake when I've created it.
Have you got any other advice for me?

Thank you
Marco

Click Add>Select the indicator>OK>Export.
Then attach that file you saved; under My Docs>NT8>Bin>Custom>Select the downloaded .zip file.

Hi Alan,

Is there a finished indicator for this available somewhere? I'd like to see it as an oscillator.

Thanks in advance!

Hello PN720,

I'm unaware of an existing finished version of this indicator, but perhaps someone on the forum can provide you with a copy.
