Stock Tracking Widget · Chrome extension

User guide

A small window on any page you browse: Vietnamese (HOSE, HNX, UPCoM, VN30 futures) and US stock prices, candlestick charts, alerts and trading calculators, without opening a price board.

PROFeatures with this label belong to the paid plan. For now, every Pro feature is free for everyone.
The extension shows data and sends signals. It never connects to a brokerage account or places orders, and nothing it shows is investment advice. Data comes from public sources and may be delayed.

01Getting started

The first time you open the widget, pick a market (VN or US) and a few stocks you follow, then press Get started. They go to your watchlist. The next step offers a first alert (the stock moving 5% or 10%).

Each new page shows only a small price bubble in the bottom-right corner. Click it to open the widget.

10Data, backups and privacy

Everything (watchlists, alerts, positions, portfolio, bots) is stored in your browser; there is no account. Export / import from the popup. Data sources: VPS, VNDirect, SSI (Vietnam), Yahoo Finance (US). When the VPS board fails, prices come from SSI; the widget says when it runs on a backup source or when prices stop updating during the session. See the privacy policy.

11FAQ

Prices don't move?
Outside trading hours the extension stops downloading prices (the phase reads "Closed"). During the session, Vietnamese prices update every few seconds, US ones every 5–15 seconds.
Why does the chart differ from my broker's board?
The chart uses adjusted prices by default. Tap Adjusted for raw prices.
Is the data exact?
Not guaranteed. It comes from public sources and can be delayed or interrupted. If the derivatives board feed fails, the VN30F reference falls back to the previous close.
Do backtests guarantee profits?
No. Test several periods and use paper trading first.
Move my data to another computer?
Export / import in the popup, or turn on sync (Pro).
