This ProBuilder code snippet is designed to find the bar numbers where the highest and lowest prices occurred within the last 100 bars. It is useful for analyzing price movements in trading data.

Massimo = 0
Minimo = 999999
BarraMinimo = 0
BarraMassimo = 0
FOR i = 0 to 99
    IF high[i] > Massimo THEN
        Massimo = high[i]
        BarraMassimo = i
    ENDIF
    IF low[i] < Minimo THEN
        Minimo = low[i]
        BarraMinimo = i
    ENDIF
NEXT
EventoMassimo = BarIndex - BarraMassimo
EventoMinimo = BarIndex - BarraMinimo

Explanation of the Code:

• The variables Massimo and Minimo are initialized to 0 and 999999, respectively, to store the maximum and minimum prices found within the loop.
• BarraMinimo and BarraMassimo are initialized to 0. These will store the bar numbers (indices) where the minimum and maximum prices occur.
• A FOR loop iterates from 0 to 99, which corresponds to the last 100 bars from the current bar.
• Within the loop, the IF statements check if the current high or low prices are greater than Massimo or less than Minimo. If true, the respective maximum or minimum values and their bar indices are updated.
• After the loop, EventoMassimo and EventoMinimo calculate the actual bar numbers relative to the current bar index. This is done by subtracting the bar indices of the maximum and minimum from the current bar index (BarIndex).

This code is particularly useful for traders and analysts who need to pinpoint significant price levels and their occurrences over a defined historical period.
