Looking for a pcf for a 52 week low within last 30 daily bars

There are two different ways to interpret this question which would result in slightly different lists of symbols.

The first would check for the lowest low during the most recent 30 trading days to be the lowest low in the most recent 252 trading days.

MINL30 = MINL252

The second would test each of those 30 bars individually to see if one of them was at a 252 bar low at the time.

L = MINL252 OR L1 = MINL252.1 OR L2 = MINL252.2 OR L3 = MINL252.3 OR L4 = MINL252.4 OR L5 = MINL252.5 OR L6 = MINL252.6 OR L7 = MINL252.7 OR L8 = MINL252.8 OR L9 = MINL252.9 OR L10 = MINL252.10 OR L11 = MINL252.11 OR L12 = MINL252.12 OR L13 = MINL252.13 OR L14 = MINL252.14 OR L15 = MINL252.15 OR L16 = MINL252.16 OR L17 = MINL252.17 OR L18 = MINL252.18 OR L19 = MINL252.19 OR L20 = MINL252.20 OR L21 = MINL252.21 OR L22 = MINL252.22 OR L23 = MINL252.23 OR L24 = MINL252.24 OR L25 = MINL252.25 OR L26 = MINL252.26 OR L27 = MINL252.27 OR L28 = MINL252.28 OR L29 = MINL252.29
