Build: 2026-05-18 09:50 — percentage formula + combined chart + separate peak charts.
Upload a CSV with at least date, open, and close columns. The program adds peak5, peak21, and peak63.
Percentage formula:
peakXp = 100 - ((highest close from previous Xp rows / current open) * 100)
Xp is 5, 21, or 63. Negative values mean current open is below the previous close peak.
Option A: combined percentage chart. Tap, click, or press-hold on the chart to show the date and peak values. Negative values mean current open is below previous close peak.

Separate Peak Charts
Option D: each peak series gets its own Y-axis, so peak5, peak21, and peak63 are easier to inspect separately.
