What changed

• Language switcher in the Signals header — English, 繁體中文, 简体中文, or Español without leaving the app.
• Chart legends use shorter names (Suggested entry window, Daily model view) with an info icon for the 7-day rule and reference details (hover or tap).
• Versus the market is now a 2×2 board (leading / up but behind / down less / weak) with a plain-language sentence and a green dot showing where this ticker sits over the last 60 days.
• Strategy history opens with one summary sentence, three hold-period cards (win/loss bar and “$100 → amount”), and a win-rate heatmap by market situation. Your current quadrant is highlighted.

Other fixes

• The vs-market ticker dot is easier to see in dark mode and sits clearly inside its quadrant.
