Calculating the Mean of a Divergence Index over a Specified Period

[ZackeryE21]

I have an indicator that calculates what percentage a given moving average is of a stock price.

if
Stock Price = $100
and
Moving Average = $110
then
Divergence = 110% (Moving Average is 10% above Stock Price)

So, my question is, how do I access the Divergence amount over a given period, and get a mean from that? I know how to calculate mean and everything of course; I just don't know how to store the data as I'm plotting the Divergence.

Here's the code for the Divergence Index indicator itself:

declare once_per_bar;
declare lower;

input price = close;
input aggregationPeriod = AggregationPeriod.DAY;
input length = 200;

def EMA = ExpAverage(price, length);
def divergence_value = (EMA / close) * 100;

plot Divergence = divergence_value;

Thanks so much!

you don't have to store anything. on every bar, values are saved in the variables. you can use offsets to read a variable on a different bar, or use a function to read several values across a range of bars.

maybe this example will help you figure out what you want to.
copy this to the end of your code

# calc an average , on each bar, by looking back at x bars
input avg_len = 10;
def avg = sum(Divergence, avg_len)/avg_len;
#
addchartbubble(1, low,
Divergence + "\n" +
avg
, color.yellow, no);
#

i don't know which method you want to use to calculate a mean
