A lower low (LL) is a swing low that prints below the previous swing low. A sequence of LLs paired with lower highs is the structural definition of a downtrend. The first higher high after a sequence of LLs typically signals the start of a reversal.
Lower lows are mirror-symmetric to higher highs and used the same way in trend identification, anchoring short-side bias and defining levels that bulls must reclaim to flip the structure.
Like all swing-based observations, an LL is confirmed only after the next N bars print without breaking it — there is always an inherent lag.
Example
Prior swing low at 49,000. Price drops, prints a new swing low at 48,200 — that 48,200 is a lower low, confirming downtrend continuation.
