Basic programming question

[winJR]

Hello, new to Ninjascript. I have a question. I am trying to paint the bars a color when 3 parts of the macd are above the zero line. (macd, avg, diff), or when two are above and one is below, etc. I use barcolor = Color.Red and I can get it to work if I only program for one of the variables. My challenge is getting the coding correct when I want all three variables (mulitple conditions in other words). I am doing something wrong. Using "and" to add multiple conditions doesnt seem to work.
For example:
if A > 0 and
B > 0 and
C < 0
BarColor = Color. Red ;
this doesnt seem towork. I am probably messing up with the basic coding. Help...lol.

You would need to do something like:

if (MACD(12, 26, 9).Macd[0] > 0 && MACD(12, 26, 9).Avg[0] > 0 && MACD(12, 26, 0).Diff[0] > 0)
    BarColor = Color.Red;

Ray, you are awesome. I used the &&; however, I am still getting an error.
"Cannot apply indexing with [] to an expression of type 'method group'

here is my code:
if (MACD(12,26,9).MACD[0] > 0 && MACD(12,26,9).Diff[0] > 0 && MACD(12,26,9).Avg[0] > 0)
BarColor = Color.Red ;

I edited my original post. Changed the MACD[0] to Macd[0].
