TradingView Reader (Read-Only)

Reads TradingView's desktop macOS app for quotes, options chains, and chart state via opencli and a CDP attach to the running TradingView.app process. Powered by the tradingview plugin in this repo's opencli-plugins/tradingview tree (a separate plugin from opencli's built-in adapters, installed via opencli's monorepo subpath syntax).

This skill is read-only. Designed for analysis: pulling options chains, checking IV/greeks, capturing chart state. It does NOT place trades, post ideas, modify watchlists, or change chart layouts.

Important: Unlike browser-based opencli readers (twitter, linkedin), this one talks directly to a running TradingView desktop app over Chrome DevTools Protocol. The user must (a) have TradingView.app installed, and (b) be logged in inside that app. The plugin handles relaunching with the debug port.

How it works: data commands harvest session cookies via CDP Storage.getCookies, then fire HTTP requests from Node directly. Page-context fetch is blocked by browser CORS preflight even from TradingView's own pages — the desktop app uses Electron's main process (Node network stack) to bypass this, and we replicate that path. No Browser Bridge extension required, no apps.yaml registration needed.

Step 1: Ensure opencli + Plugin Are Installed and Ready

Current environment status:

!`(command -v opencli && opencli tradingview status 2>&1 | head -5 && echo "READY" || echo "SETUP_NEEDED") 2>/dev/null || echo "NOT_INSTALLED"`

If the status above shows READY, skip to Step 2. Otherwise:

NOT_INSTALLED — Install opencli

npm install -g @jackwener/opencli

Requires Node.js >= 21 (or Bun >= 1.0).

SETUP_NEEDED — Install the TradingView plugin and launch with CDP

The TradingView adapter is not built into opencli — it's a separate plugin:

# Install the plugin
opencli plugin install github:himself65/finance-skills/tradingview

# Relaunch TradingView.app with CDP enabled (one-time per session)
opencli tradingview launch

The launch step quits the running TradingView and reopens it with --remote-debugging-port=9222. Warn the user to save chart layouts first if they have unsaved drawings.

Common setup issues

| Symptom | Fix | |---|---| | opencli: command not found | npm install -g @jackwener/opencli (Node ≥ 22 for built-in WebSocket) | | Unknown command: tradingview | opencli plugin install github:himself65/finance-skills/tradingview | | Cannot reach CDP at http://127.0.0.1:9222 | App not launched with debug port — run opencli tradingview launch | | No tradingview.com cookies found | App is open but logged out — log in inside the desktop app | | No TradingView tab found | Open any chart or symbol page in TradingView, then retry | | Empty chain / 0 contracts | Subscription tier on the logged-in account doesn't include options for this symbol |

Step 2: Identify What the User Needs

Setup / chart inspection

| User Request | Command | Key Flags | |---|---|---| | Setup / connection check | opencli tradingview status | — | | Relaunch app with CDP | opencli tradingview launch | --port 9222 | | What's on the chart | opencli tradingview chart-state | --tab <id> | | Screenshot a chart | opencli tradingview screenshot --output ~/charts/nvda.png | --tab <id> |

Step 3: Execute the Command

General pattern

# Use -f json or -f yaml for structured output
opencli tradingview options-chain --ticker SNDK --expiry 2026-05-22 -f json
opencli tradingview options-chain --ticker NVDA --strikes-around-spot 8 -f csv
opencli tradingview quote --ticker SPY --exchange NYSEARCA -f json

Key rules

1. Run opencli tradingview status first if connectivity is uncertain — it reports CDP connection state and active TradingView tabs.
2. Use -f json for programmatic processing (LLM context, downstream skills).
3. Filter by expiry and --strikes-around-spot — full chains can be 3,000+ rows; an unfiltered dump is rarely what the user wants.
4. Default --exchange NASDAQ for US equities; require explicit --exchange for ETFs (e.g. SPY = NYSEARCA, QQQ = NASDAQ) or non-US listings.
5. For screener, --columns is critical — it controls both the request and the output table. Include name and any field used in --filter or --sort. Append |TF for an indicator's timeframe, e.g. RSI|60 for 1-hour RSI. The default columns are sensible for stocks but should be replaced for crypto / forex / futures (different field catalogs).
6. For screener, --filter is JSON — array of {left, operation, right} clauses. Always single-quote the JSON in shell to avoid escaping issues. See references/commands.md for the operations cheat sheet.
7. For news, narrow the feed early — the global feed is firehose-level. Use --symbol, --category, --section, or --provider before raising --limit.
8. For search, prefer it over guessing — when the user gives an ambiguous ticker (e.g. "SPY" without exchange), run search --query SPY first to confirm the listing, then pass --exchange to subsequent commands.
9. For watchlists and alerts, default to summary — a user asking "what's in my watchlists?" wants list names + counts, not every symbol.
10. NEVER call any write operation. This skill is read-only — no trades, no watchlist edits, no alert creation/deletion, no chart writes. The plugin intentionally does not expose write endpoints (/append, /replace, /create_alert, etc.).

Output format flag (-f)

| Format | Flag | Best for | |---|---|---| | Table | -f table (default) | Human-readable terminal output | | JSON | -f json | Programmatic processing, LLM context | | YAML | -f yaml | Structured output, readable | | Markdown | -f md | Documentation, reports | | CSV | -f csv | Spreadsheet export |

Output columns

• quote — symbol, close, change, change_abs, currency, time
• options-chain — expiry, dte, strike, type, bid, ask, mid, iv, delta, gamma, theta, vega, rho, theo, bid_iv, ask_iv, symbol
• options-expiries — expiry, dte, contracts_count
• screener — dynamic; one column per --columns entry, plus symbol. (Default: name, close, change, volume, market_cap_basic, sector.tr.)
• search — symbol, description, type, exchange, country, currency
• news (list mode) — id, published, provider, title, urgency, related_symbols, link
• news (story mode, --id set) — id, published, provider, title, body, tags, link
• watchlists — id, name, symbol_count, symbols
• alerts — id, name, symbol, type, condition, value, active, status, fired_at
• chart-state — layout_id, symbol, interval, url
• screenshot — path, bytes

Step 4: Present the Results

1. Lead with the structure summary — for an options chain, state spot price, expiry being shown, ATM strike, and IV regime first; then the table. For a screener, lead with the count of matches and the filters applied.
2. Filter aggressively before showing — never paste a 3,000-row chain or a 500-row screener. Default to ATM ± 6 strikes per expiry for chains; for screeners cap to top 20 unless the user asks for more.
3. Highlight skew — when showing both calls and puts, note IV skew direction if material.
4. For chart-state, report layout id + symbol + interval + URL succinctly; offer to screenshot.
5. For news (list mode), group by provider and lead with timestamps in the user's likely timezone (or always UTC ISO if uncertain). Include the link so the user can open the story. For story mode (--id set), the body is plain text — present it as-is, optionally trimmed.
6. For watchlists, summarize counts before listing symbols (e.g. "3 watchlists: Earnings (24 syms), AI plays (12 syms), Hedges (8 syms)"). Don't dump 100-symbol watchlist contents unless asked.
7. For alerts, group by status (active vs triggered/fired) and order recent firings by fired_at desc. Don't expose alert ids unless the user explicitly asks.
8. For screener results, surface the top movers / extreme values in plain prose first (e.g. "highest market cap NVDA at $4.2T, 12 names below the RSI<30 threshold"), then the table.
9. Treat sessions as private — never expose CDP target IDs, cookies, or layout IDs unless the user asks.
10. Cross-reference with Funda when the user is making a trade decision — TradingView's options/screener data is convenient but can lag; for trade entry analysis, also fetch from the funda-data skill and reconcile.

Step 5: Diagnostics

opencli tradingview status

Returns CDP connection state and active TradingView tabs. If CDP is down, run opencli tradingview launch to relaunch with the debug port.
