Hi, I’m new to coding but have been through the introductory videos in detail. I’d like some help with the following simple programme I’ve created, which I’d like to return as a histogram on a separate panel below a price chart.

Although I have specified three different results [1, -1, 0], the resulting indicator only shows one horizontal line across the panel at the zero level with the area below shaded purple. The variable for the Exponential Average [short] I have included in the variables section [wrench indicated alongside above the code lines] as 9. Here is my programme code thus far:

//Variables
a = ExponentialAverage[short](close)
b = MACD[12,26,9](close)

IF a > a[1] AND b > b[1] THEN
   Result = 1
   IF a < a[1] AND b < b[1] THEN
      Result = -1
   ELSE
      Result = 0
   ENDIF
ENDIF

RETURN Result

Basically, if the current value for the EMA is higher than its value for the period/bar/candle immediately preceding [1], and if the MACD-H value [Line-Signal] is higher than that of its immediately preceding value [1], then I’d like the histogram to show +1. The rest should be clear…

Also, I need reminding how to return the indicator as a histogram.

Apologies for the basic nature of the request to all you pros, but any help would be appreciated. Many thanks, Steve
