HH/HL/LH/LL

The script works by detecting swing highs and swing lows with a simple pivot function (ta.pivothigh / ta.pivotlow) using a fixed 2-bar lookback and confirmation window. Each new pivot is compared against the previous confirmed pivot of the same type:

If a swing high is greater than the last swing high → it is labelled HH.

If a swing high is lower than the last swing high → it is labelled LH.

If a swing low is greater than the last swing low → it is labelled HL.

If a swing low is lower than the last swing low → it is labelled LL.

To keep the chart clean and readable, the indicator:

Plots only the two-letter labels (HH, HL, LH, LL) with no background box.

Uses red text for highs and green text for lows.

Places labels directly at the pivot bar (with the necessary confirmation offset).

Keeps labels small (size.tiny) to avoid clutter.
