Discrepancy between plotted SMA and Indicator SMA?

[Bogomir28]

Hi, i'm bewildered by an apparent discrepancy between plotted values and indicator values.

I've written a basic piece of code which colors bars green if they close above a 20-period SMA, and red if they close below.

When applied to price action, it seems to work ok. But if i add a visual SMA of the same period to the chart, its clear that its not working correctly. Infact the indicator seems to be making its calculations around a 10-period SMA, not 20.

Really don't understand why its halving the input period.. am i overlooking something?

Thanks!! Damien

Here is your calculation line:

 
double SMA1 = SMA(Inputs[0], (int)(Period1 / 2))[0];

If Period1 == 20, as you have it assigned, then Period1/2 == 10. Ergo!

Oh, heck! Thats pretty elementary. I pinched that bit of code off something else then forgot to check it closely. Anyway, thanks very much koganam!
