Help writing acceleration indicator

[markp77]

Hi!

I was wondering if someone could help me write an acceleration indicator. It would basically measure the slope of the slope of the graph and plot it as an oscillator.

This is how far i am

protected override void OnBarUpdate()
        {
            accel = ((Typical[0] - Typical[5]) / 5) - (Typical[5] - Typical[9]) / 5) / 5;
            Value.Set(accel);
        }

This isn't giving me any errors when I compile, but nothing is showing up on the graph.
Thanks in advance!

This indicator coding error seems to come up fairly regularly here. Maybe it would be helpful to notify the user of this problem in a more obvious way, such as a message directly on the bottom of the chart, when this exception happens. Clicking the message could link to the help with some related hints/examples.

Hello Anagoge,

I will forward your suggestion to our development team and ask them if they can add this to the list of future considerations for the software.

Thank you for your feedback.
