Some basic coding assistance please

[GeorgeW]

Hello,

I am working on some coding for an indicator. The basic code is as follows:

if (IndicatorA[4].ApproxCompare(20)==0 && IndicatorA[3] !=50)
Do something.

I am finding that "Do something" occurs even when IndicatorA[3] == 50, which is not what I want. What is the problem with my code (I suspect it may be to do with the not equal to statement)?

Also, if I want to do some calculations on bars either side of a swing high, what is the easiest way to identify the swing high and then the barsAgo of the bars either side of it?

Thank you

Hello GeorgeW,

Thank you for your note.

It could be that IndicatorA[3] is 50.90 which may be causing it to be true. I would suggest seeing the following sample to introduce logic which would take the difference between IndicatorA[3] and 50, and see if it’s an amount smaller than an acceptable amount.

Regarding identifying the swing high/low value you could use,

Print(Swing(5).SwingLow[0].ToString());

To identify how many bars ago the swing low was, you could use something like the following to search the last 30 bars for the swing low bar.

Print(Swing(5).SwingLowBar(0,1,30).ToString());

Please see the following section on using the Swing indicator via NinjaScript.

Thank you AlanP.

I had tried it with ApproxCompare but just couldn't figure out how to write the code correctly. This works:
if (IndicatorA[4].ApproxCompare(20)==0 && IndicatorA[3].ApproxCompare(50)!=0)
Do something.
