🧩 dsh-ticker-jp

English · 简体中文 · 日本語

A small floating stock ticker for the top-right corner of DeepSeek Harness. It supports worldwide markets via Yahoo Finance — Japanese stocks (.T), US stocks, Hong Kong (.HK), mainland China (.SS/.SZ) and any other symbol Yahoo serves — with real-time quotes, a customizable watchlist and display-name aliases. Out of the box it shows the TOPIX-linked ETF and the Nikkei 225. Forked from dsh-stock-ticker: the floating-window interaction comes from upstream, while the data source was switched to Yahoo Finance to cover markets around the globe.

📸 Preview

✨ Features

• Draggable, collapsible window that follows the DSH theme
• One row per symbol: name, price, change percent; red for up by default
• Watch symbols from worldwide markets (Japan .T, US, Hong Kong .HK, mainland China .SS/.SZ…), with 4-digit shorthand and code:display name aliases
• Smart polling: when every watched market is closed, it checks once a minute instead of every 5 seconds
• Up/down colors switchable between Japanese and US conventions
• 16 UI languages, auto-detected from the browser on first run, changeable any time
• Window position, collapsed state, watchlist, palette and language all persist locally
• One-click restore to defaults

Default symbols

Display	Code	Note
TOPIX ETF	1306.T	Yahoo no longer serves the TOPIX index, so its linked ETF is used instead
日経225	^N225	The Nikkei 225 index

🚀 Install

Install from npm (prebuilt, no build approval needed), or straight from the GitHub source:

# npm (recommended)
dsh plugin --profile web add dsh-ticker-jp

# GitHub source
dsh plugin --profile web add github:MurasakiIzumi/dsh-ticker-jp

Restart DSH (or choose "restart now") and the widget appears at the top-right of the page.

⚙️ Usage

1. Click the ⚙ button in the title bar to open settings.
2. Each row is code + display-name input + remove button. Editing the name applies immediately; leaving it blank falls back to built-in shorthand → Yahoo name → code.
3. Use the box at the bottom to add symbols: 9984.T, AAPL, or 9984 (a bare 4-digit code gets .T appended, Japan only). 9984.T:SoftBank adds a symbol with an alias.
4. Palette and language controls sit in the middle of the panel and apply immediately.
5. "Restore default" returns to TOPIX ETF + Nikkei 225; "Done" closes the panel.

The same code ships in two forms: lib/ is the bundle that stays installed in DSH; host.js / client.js form the dynamic-plugin variant for temporary runs. They are functionally equivalent.

🔌 Data source

• Yahoo Finance chart API: https://query1.finance.yahoo.com/v8/finance/chart/{code}?interval=1d&range=1d
• Free, no authentication. Price from meta.regularMarketPrice, change percent from meta.regularMarketChangePercent, name from longName/shortName
• Covers worldwide markets — Japan .T, US, Hong Kong .HK, mainland China .SS/.SZ and any other Yahoo-supported exchange
• Each quote carries the exchange timezone and exchange name so the client can tell when local markets trade
• Names come from Yahoo, never a built-in table; the two defaults get shorthand names in the display layer only

🧪 Dynamic plugin (optional)

Loads without installing, for a quick trial:

1. Create a plugin with cordis_define: paste host.js as code.host and client.js as code.client.
2. Activate with cordis_run; approve the client on first run.
3. Refresh the page to see the widget.

The dynamic form behaves like the bundle. The only difference is the Host fetch path: the dynamic Host runs in a restricted sandbox and fetches through ctx.web, while the bundle uses native fetch. The RPC contract is the same.
