How to detect if in ANY candle in the past 'n' candles meet a certain requirement?

Question

I'd like to check if ANY candle in the past 'n' candles meet a certain condition.

Eg let's check if any close in the latest 20 candles was higher than 'x':

x = 2
n = 20
condition = [ANY of n] > x

Answer 1

See barssince() and an example showing how to use it here .

You can also count the number of occurrences of a condition in the last n bars using:

sum(cond ? 1 : 0, len)
