Read the tape
It watches the tape. It rings when something moves.
The Tape Bell watches the stocks you choose, reads the technicals and sends a desktop notification when a buy or sell setup appears, including pre-market gaps before the opening bell. It runs on your own Mac, under your own data accounts.
macOS download coming soon. Free, with a licence that never expires.
An alert, not a feed
Most of the time The Tape Bell is quiet. It looks at momentum, trend, volume and price structure together, and only speaks up when enough of them agree. If you hold the stock, a sell alert can fire on it too.
What it does
US and Singapore stocks
Watches US-listed stocks and ETFs, and Singapore-listed counters priced through your own broker login.
Pre-market gaps
Flags stocks gapping before the open, so you see the move before the opening bell.
Sell alerts on what you hold
Connect a broker read-only and sell alerts cover the positions you actually own. It never places, changes or cancels orders.
A dashboard of your own
Signals, holdings and alert history in a dashboard served from your Mac. Open it on your phone too if you choose.
Yours, on your machine
No The Tape Bell account and no The Tape Bell cloud. Your watchlist, holdings and alerts are stored on your Mac.

- Broker connections are read-only and optional. You can also type your holdings in by hand.
- The app ships with no market data and no one else's credentials.
- A free licence key that doesn't expire. No trial, no renewal.

The Tape Bell is a software tool, not financial advice. Its signals are mechanical and are often wrong. It does not know your circumstances, objectives or risk tolerance. Investing involves risk, including the loss of your capital. Do your own research, and consult a licensed professional where appropriate. Past signals do not predict future results.
