Build LifeStock dashboard with personalized tracking and candlestick charts

[Copilot]

Implements a Next.js dashboard that gamifies personal development by tracking 5 life pillars (Knowledge, Skills, Health, Discipline, Mood) as stock price movements with candlestick visualization.

Core Implementation

• Personalized experience: Name input on first launch, dynamic company ticker generation ([NAME] LTD. ([NAME]X))
• Candlestick chart: Real-time visualization using lightweight-charts with discipline-based wick calculations
• Price formulas: DailyChange% = (Avg - 5) * 4, NewClose = OldClose * (1 + DailyChange%/100)
• Wick volatility: volFactor = 1.8 - (discipline/10) * 1.4, higher discipline = tighter wicks
• Weekly analytics: 7-day performance reports with streak tracking, pillar analysis, best/worst days

Technical Stack

• Next.js 16.1.6 with App Router (upgraded from 14.2.3 for security)
• React 19.2.4, TypeScript 5.4.5, Tailwind CSS 3.4.3
• localStorage for client-side persistence (no backend)
• 0 npm vulnerabilities (fixed 35+ DoS, auth bypass, cache poisoning issues)

Key Files

// lib/lifestock.ts - Core formulas and data management
export function calculateDailyChangePct(avg: number): number {
  return (avg - 5) * 4;  // Avg=10 → +20%, Avg=0 → -20%
}

export function calculateHighLow(open, close, dailyChangePct, discipline) {
  const volFactor = 1.8 - (discipline / 10) * 1.4;
  const wickPct = Math.abs(dailyChangePct) * 0.35 * volFactor + 0.6 * volFactor;
  // ...
}

Original prompt

You are GitHub Copilot. Build a complete Next.js 14 (App Router) website dashboard called “LifeStock: KIRAN LTD. (KRNX)”.
Goal: Track 5 life pillars as if they move a stock price with REAL positive/negative changes.

Tech requirements:

• Next.js 14 + TypeScript + App Router
• Tailwind CSS (dark theme)
• Candlestick chart using lightweight-charts
• Persist all entries locally using localStorage (no backend)
• Mobile + desktop responsive UI
• Clean minimalist futuristic dark UI (black/blue tones, but do not hardcode too many colors; keep it simple)

Data model:

• Pillars: Knowledge, Skills, Health, Discipline, Mood (each integer 0–10)
• Daily Entry fields:
  • id (uuid)
  • dateISO (YYYY-MM-DD)
  • pillars object
  • avg (number)
  • dailyChangePct (number)
  • priceOpen, priceHigh, priceLow, priceClose (numbers)
• Starting price: 100.00 if no history

Core formulas (must match exactly):

1. Avg = (K + S + H + D + M) / 5
2. Neutral origin = 5
3. DailyChange% = (Avg - 5) * 4
   • Avg=10 => +20%
   • Avg=0 => -20%
4. NewClose = OldClose * (1 + DailyChange%/100)
5. NewPrice cannot go below 0

Candlestick rules:

• Open = previous day close (or 100 for first day)
• Close = NewClose
• Wicks depend on Discipline (higher discipline = smaller wicks, lower discipline = larger wicks)
  • Implement a reasonable volatility factor such as:
    volFactor = 1.8 - (discipline/10)1.4
    wickPct = abs(dailyChangePct)0.35volFactor + 0.6volFactor
    high = max(open, close) * (1 + wickPct/100)
    low = min(open, close) * (1 - wickPct/100)

App pages/components:

1. / (Dashboard)

   • Header: “LifeStock: KIRAN LTD. (KRNX)”
   • Shows last close price
   • Shows trend label based on latest Avg:
     • Bull Market if Avg >= 6.5
     • Stable Market if 4.8 <= Avg <= 6.4
     • Bear Market if Avg < 4.8
   • Candlestick chart with full history
   • Daily Entry card:
     • Date picker default today
     • 5 sliders 0–10 with current numbers
     • “Save Day (Add/Replace)” button (if date exists, replace; else add)
   • Preview card:
     • shows Open, projected Close, Avg, DailyChange%
     • shows a short “Market Read” message (bull/stable/bear)
   • Recent days list (last 10–12 entries)
   • Reset button to clear localStorage (with confirm)

2. /weekly (Weekly earnings report)

   • Automatically compute the last 7 days (or fewer if not available)
   • Show:
     • Weekly % change from first open to last close
     • Best pillar (highest average across the week)
     • Weakest pillar (lowest average across the week)
     • Streak count: consecutive days with Avg >= 5 (green or neutral)
     • Biggest up day and biggest down day (by dailyChangePct)
   • Include a “Back to Dashboard” link

Other requirements:

• Sort entries by dateISO ascending
• Ensure no duplicate date entries (replace on save)
• Use client components where needed
• Add a small utility layer: clamp(), round2(), todayISO(), loadEntries(), saveEntries()
• Provide instructions in README.md: install, run, build

Deliverables:

• Full project file structure + code for all files:
  • app/page.tsx
  • app/weekly/page.tsx
  • app/layout.tsx
  • app/globals.css
  • tailwind.config.ts
  • postcss.config.js
  • package.json dependencies list
  • components/Chart.tsx (if you prefer to split chart logic)
  • lib/lifestock.ts for formula functions (optional)
  • README.md

Important:

• Make the code production-quality: correct TypeScript types, no runtime errors, guard localStorage for SSR, use “use client” where necessary.
• Keep UI clean and readable. Don’t add unnecessary animations.
• Implement the chart properly with resize handling.

Already done! The application no longer uses "KIRAN LTD" - it was replaced with a personalized name input system in commit 7061931.

When users first launch the app, they enter their own name, which is then used throughout the dashboard (e.g., "ALEX LTD. (ALEXX)" for a user named Alex).

The "KIRAN LTD" you saw in the PR screenshots was just test data from development. The actual code has no hardcoded names.

Fresh start (name input):

After entering "Alex":
