In ThinkOrSwim's ThinkScript, I'm trying to create an indicator which displays an average of the past 5 bars which had a range of more than 10 ticks.

For example, lets say last 10 bars had the following ranges (in ticks): 20, 22, 25, 17, 10, 7, 8, 8, 9, 8.
I want my indicator to display a value of 18.8 (i.e, (20+22+25+17+10)/5 = 18.8).

I'm fairly new to ThinkScript and so far I've been able to program an indicator which displays the average of the last 5 bars but I want to make one which will only average those bars which fulfill a certain criteria.

Any help would be appreciated!

Not sure this is of any value other than to see how the fold expression is used

input Threshold = 10;
input n = 10;

def Avg = (fold i = 0 to n
with p
do p + getValue(if close > Threshold then close else 0, i, n - 1)) / n;
addLabel(1, "Avg Value " + Avg, Color.White);
AddLabel(1, "Avg " + (Average(close, n)));

Thanks for the reply. But wouldn't the above code average the last 10 bars regardless of whether it had higher than 10 ticks? If the last 10 bars all had less than 10 ticks then the value returned by this code would be 0, would it not?
