SMA producing NAN result.

[Dr Kerry]

In my script I have declared 6 double series call them A, B, C, D, E, and F for simplicity.

Within OnBarUpdate I then have:

A[0] = High[0] - Low[0] ;
B[0] = Math.Abs(Close[0] - Open[0]) ;

C[0] = A[0] - B[0] ;
D[0] = SMA(C,6)[0] ; // This SMA produces a proper result

E[0] = C[0] / B[0] ; // This is just C normalized to B, i.e. (A - B) / B
F[0] = SMA(E,6)[0] ; // This Produces the NAN result


All of the series A through E produce proper results but series F gives NAN for some reason.

If, in series E, I replace B[0] with a constant such as:

E[0] = C[0] / 9.5 ;

Then F produces a correct result.

F[0] = SMA(E,6)[0]; // Produces a correct result when B[0] is replaced with a constant.

So why, in the series F, is the SMA choking on the division by B[0], yet the series E is just fine with the division by B[0]?

Thank you for your insights and fixes.

Hello Dr Kerry,

From the given sample I don't see anything specifically wrong. Are you certain that you are getting populated values in the E series? Adding a print right after setting it would be a good way to make sure the series is populated before passing it to the SMA. I would otherwise suggest making a small sample script that has those series and math and then attach it so that we can see the full extent of what you had done.
