TradingView Chart Snapshot Skill

What This Skill Does

1. Checks TradingView Desktop is reachable (port 9222)
2. Switches TradingView to the requested ticker
3. Captures a screenshot of the chart
4. Saves the image to PortfolioAnalysis/screenshots/{YYYY-MM-DD}/{TICKER}.png
5. Reports the saved file path

---

Phase 1 — Parse Argument

Extract the ticker from the trigger:

• /tv-snapshot CRWV → ticker = CRWV
• "snapshot NVDA" → ticker = NVDA
• "chart screenshot INTC" → ticker = INTC

If no ticker provided, ask: "Which ticker would you like to snapshot?"

---

Phase 2 — Health Check

python3 "$(find plugins/tradingview/scripts ~/.claude/plugins/cache -name tv_health_check.py -path "*/tradingview/*" 2>/dev/null | sort | tail -1)" --json

If TradingView is not running, print:

TradingView Desktop not detected on port 9222.
Chart snapshots require TradingView Desktop to be running.

Launch it with: python3 plugins/tradingview/scripts/tv_launch.py
Or manually:    open -a TradingView --args --remote-debugging-port=9222

Stop if TradingView is not available — screenshots cannot be taken without it.

---

Phase 3 — Switch Chart to Ticker

node tradingview-cdp/cli.js quote TICKER

This verifies the ticker is accessible. The screenshot will capture whatever chart is currently active in TradingView Desktop — switch to the ticker manually in TradingView before running if needed.

---

Phase 4 — Capture Screenshot

# Determine today's date for the save path
DATE=$(python3 -c "from datetime import date; print(date.today().isoformat())")
SAVE_DIR="PortfolioAnalysis/screenshots/$DATE"
mkdir -p "$SAVE_DIR"

# Capture screenshot — saved to PortfolioAnalysis/screenshots/{date}/{TICKER}.png automatically
node tradingview-cdp/cli.js screenshot --output "$SAVE_DIR/$TICKER"

---

Phase 5 — Report

╔══════════════════════════════════════════════════════════════════╗
║              CHART SNAPSHOT SAVED                                ║
╚══════════════════════════════════════════════════════════════════╝

Ticker:   CRWV
Saved:    PortfolioAnalysis/screenshots/2026-05-07/CRWV.png
Chart:    TradingView Desktop (live view at time of capture)

Error Handling

Situation	Response
TradingView not running	Print launch instructions and stop
symbol command fails	Report error with the exact CLI error message
screenshot command fails	Report error, do not save partial file
Save directory creation fails	Report filesystem error

---

Hard Rules

1. Always switch to the requested ticker before screenshotting — never capture the wrong chart
2. Always report the exact saved path so the user can find the file
3. Require TradingView to be running — no fallback for screenshots
