Delta change Percent indicator

This script calculates the percentage change in orderflow delta (close-only) between the current and previous bar.

delta → current orderflow delta value.

delta_prev → delta value from the previous bar.

delta_change_pct → percentage change from the previous bar, using the absolute previous value to avoid sign distortion.

Very large values (over 999) are scaled down to actual percentage form so they don't show as "k".

Green bars indicate a positive change, red bars indicate a negative change.

An alert is triggered if the percentage change exceeds 30%.
