Detects pivot highs/lows by bar confirmation

[samhanoh]

I need a ThinkScript that:

• Detects pivot highs/lows by bar confirmation: N bars to the right (default N = 50, user input).
• Shows exactly one bubble only when a pivot is confirmed (i.e., on bar t+N for a pivot at t):
  • Green bubble for confirmed pivot high, red for confirmed pivot low (black text).
  • Bubble text = bar count between the previous confirmed pivot and this pivot.

My goal is just to count the number of bars between each confirmed high and low in the last 300 bars, with at least 50 bars between pivots, to check if there’s a cyclical pattern like W.D. Gann’s time cycles.

A single bubble is enough — just show the number of bars that have passed from the high to the low or vice versa, with a minimum of 50 bars.

We’ll take historical data up to 300 bars back.

My goal is to try to identify repeating (cyclical) patterns.
