trying to convert band distance to a TickSize value

[stafe]

i keep getting a CS0120 error on compile - and the error mssgs were different...
i was trying to change BandWidth from points to ticks - i can't figure out what i need to make it work....

i tried changing [Range(1, int.MaxValue)]
to [Range(1, double.MaxValue)]
but that didn't work - maybe wrong syntax

i also tried to define a private double bandWidth = 9 * TickSize;
but i got another different compile error....
??

Hello,

Thank you for the question.

To convert how this property is used, you would need to instead change how this is used in OnBarUpdate.

The public property should already be configured correctly to allow for a number to be entered. How that is related to a number of Ticks would occur in OnBarUpdate:

Here is one example of converting the Input to a number of Ticks.

TopBand[0]        = ((max0 + min0) / 2 + (BandWidth * TickSize));

In this case, assuming BandWidth was set to 2 in the user interface, it would be (max0 + min0) / 2 + 2 Ticks.

I look forward to being of further assistance.

thanks so much.... i had come across this with NT7 long time ago and couldn't remember - it was so straight forward... TopBand is already a declared double....
