Tradingview Reader

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.

Headless alternative: for plain quotes, TA readouts, screeners, futures, or a greeks-free options chain, prefer the sibling tradingview-mcp skill (bundled MCP server, no desktop app, no CDP relaunch). Use this skill when you need greeks / per-strike IV skew, expiries with contract counts, or account-bound data (watchlists, alerts, charts, TV news).

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 >= 24 — the tradingview plugin installed in the next step declares engines.node >= 24.

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

Step 2: Identify What the User Needs

Setup / chart inspection

Quotes + options

Screener

News

Watchlists + alerts

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.
