Stock Ticker

The watchlist

The page opens on five defaults: Meta, Apple, Nvidia, Google, Microsoft. Make it yours. The field above the list searches about 9,500 US-listed stocks, funds, FX pairs and crypto by ticker or company name; pick a match and it lands in the list. Each symbol gets its own cell: price, day change, a sparkline. The row of ranges above the cells, 1D through ALL, redraws every sparkline at that span. The header checkbox turns the scrolling strip off.

Tap a cell and it pushes a detail screen: the day's numbers, market cap, P/E, EPS, dividend yield, and a bigger chart with its own range tabs from one day to everything. The address bar carries #s=NASDAQ:AAPL while the screen is open, and that link reopens the same screen, on any symbol, listed or not.

Housekeeping lives behind Edit. It reveals × to remove and ≡ to reorder: drag with a pointer, or on the keyboard, where space lifts a row, arrows move it, and space drops it. Edit is also where watchlists are managed. Up to eight named lists, one showing at a time; the switcher stays out of the way until a second list exists.

The lists live in localStorage. They survive reloads and restarts in this browser, on this device, and go no further: no account, no sync, no database on my end. Clearing site data clears them. There is no export either, so a list built on a laptop stays on that laptop.

None of which makes it private from TradingView. Every symbol you add is passed to them to draw, so they see the list, your address, and the page you came from. The honest version of the claim is that nothing reaches a server of mine, because I don't have one.

Symbol formats

Search covers the US listings, cap-ranked so the match you meant comes up first. The same field still takes anything TradingView can resolve, typed raw: exchange-prefixed forms like NYSE:BRK.B and AMEX:VOO, FX pairs (EURUSD), crypto (BTCUSD, COINBASE:ETHUSD). A bare ticker the directory knows is upgraded to its listed form on the way in: aapl becomes NASDAQ:AAPL.

Outside the directory, bare tickers are first match, not canonical, and the first match is not always the famous one. SPX gets you SpaceX, not the S&P 500. Index and futures symbols mostly don't resolve at all on the free tier: ask for SP:SPX or CME_MINI:ES1! and the cell says the symbol is only available on TradingView, which is their way of saying that data costs money. TradingView's search gives the canonical form.

The cap is 25 symbols a list. That is a rendering budget, not a philosophy: each one is its own frame.

Where the numbers come from

TradingView, through its free embeddable widgets. No key, no account. That is also the constraint. US equity prices run about fifteen minutes behind, more on some exchanges, and TradingView decides what happens inside the frames. This is a glance, not a trading desk, and not advice.

Every free quote API I checked, Alpha Vantage and Finnhub and Polygon and Twelve Data, either restricts redisplaying quotes on a public page or charges for the right. An embed is the honest way to do this for nothing.

If the quotes don't load

A short note takes the place of the quotes. Usually that means a privacy extension or a network filter is blocking TradingView. It can also mean this site's content-security-policy hasn't been told to allow them, which is my fault rather than yours. Either way your saved symbols are untouched, and they come back when the quotes do.
