Swing Low
A swing low is a local minimum selected through comparisons with candles or moves on both sides. When right-hand candles are required, confirmation is delayed. Parameters and equal-low tolerance affect detection; a single higher low does not by itself establish an entire trend.
Illustrative example
How does it work in practice?
Assume five candle lows are 105, 103, 100, 102 and 104. A two-bars-on-each-side rule confirms the low at 100 only after the fifth candle; earlier it was merely a candidate.
A case to work through
A lower low during confirmation
A hypothetical candidate on bar 20 has low=50; two right-hand bars must have higher lows.
- Bar 21 has low=52 but bar 22 has low=49.
- The second right-hand bar is below 50, so the candidate fails the rule.
What follows? Do not use low=50 as a confirmed pivot under this method.
Example boundary: Equal-low tolerance needs its own rule; wider windows change pivot selection.
A useful distinction
Swing Low / Swing High
Swing low selects a minimum; swing high selects a maximum using a specified comparison count.
Check your understanding
Reject a candidate violated before its confirmation window ends.

It is satisfied after the second bar closes
Both right-hand lows exceed 30.
