问题
I'd like to check if ANY candle in the past 'n' candles meet a certain condition.
E.g. let's check if any close in the latest 20 candles was higher than 'x':
x = 2
n = 20
condition = [ANY of n] > x

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)
