Read the tape
It watches the tape. It rings when something moves.
The Tape Bell reads the market so you can decide with the facts in front of you.
- It watches. The stocks, ETFs, REITs and crypto you care about, and rings when something is worth a look.
- It shows your whole portfolio, honestly. What you paid, which currencies you're exposed to, where you're concentrated, and what you've actually made.
- It keeps score in the open. It scores its own alerts, bad months included, where you can see them.
- It stays with you. It runs on your own computer, so your data stays with you, and every decision stays with you.
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.
One bell for the whole household
Two people, three brokers, five accounts? Link them all. The Tape Bell has no limit on how many broker logins it syncs, so a couple, a family or friends who invest together see every position in one portfolio and get sell alerts on all of it.
- Link every login you have, at every broker you use. Two Tiger logins, a joint and a personal Saxo, a partner's moomoo: each one is added in setup with no cap.
- Several accounts under one login are picked up on their own.
- One portfolio: totals, asset mix, sectors and gains across every linked account, with each login still named so you can tell whose is whose.
- Sell alerts cover every position in every linked account, not just one person's.
- Each person signs in to their own broker or creates their own read-only key, and the app never places a trade.
- Free, with no charge per account or per person. Your licence covers your household and your friends and relatives.
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.
- Market data comes from your own free brokerage data account (supported brokers), with Finnhub (free, optional) for fundamentals and earnings dates.
- 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.
What you need
A Mac
macOS 11 or later.
A free brokerage data account
For US price data. The free plan uses a single-exchange feed, so prices can differ slightly from the consolidated tape. See which brokers.
Optional: your broker
Tiger, moomoo, Saxo, Longbridge, eToro and more, plus aggregators and CSV import. See the list.
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.
