Illiquid names often deserve a band. Liquid majors may reward a tighter shelf. The lab does not force one style. We score confluence, then decide how wide the mark should be so your stop and your patience match the instrument.
If your stop never fits inside the band without becoming irrational, the trade idea is too large for that level. Shrink the ambition or wait for a clearer structure.
Precision is a tool, not a personality trait. Quiet paper notes beat loud certainty on a crowded chart.
