Investopedia: Best Short Term Stock Screener, 2024
A real Top List built from filters.
The short answer: In TI Pro, an alert window with filters but no alerts automatically uses the Heartbeat alert and streams, in real time, the stocks that meet your filter criteria, so the window works as a streaming screener. Top Lists show a ranked list every 15 seconds. The AI Assistant can build either window from plain English, and the Formula Editor, in every TI Pro plan, adds your own filters.
In one minute
A streaming stock screener, in one minute
Top Lists (Screeners), the screener, show a ranked list of stocks that pass your filters, updated every 15 seconds.
A filters-only alert window streams the stocks that meet your criteria. Select filters and no alerts, and TI Pro uses the Heartbeat alert automatically.
The AI Assistant can build either window from a sentence, and the Formula Editor adds your own filters. Both are in every TI Pro plan.
Heartbeat
How a filters-only alert window streams
Settings
Every TI Pro alert window needs at least one alert. If you pick filters and leave the alerts empty, the window selects the Heartbeat alert for you. Heartbeat is based on time rather than a trade: each stock that passes all your filters gets a row reading "All filters satisfied", streamed into the window in real time. By default each matching stock repeats about every 5 minutes, and the optional Minutes setting changes that.
A real filters-only alert window in TI Pro, from the Heartbeat help page (December 20, 2023). Each heart row is a stock that passes every filter. Example data, not a recommendation.
The result is a live stock screener in an alert window: a running feed of the stocks that meet your criteria, with whatever columns you choose. Filters combine with AND, so a stock has to pass every one.
The Select Alerts tab with only Heartbeat checked. The optional Minutes box sets how often each stock repeats. From the Heartbeat help page.
Screener
Top Lists (Screeners): the ranked board every 15 seconds
Top Lists rank the stocks that pass your filters on 249 filters and sort columns, and update every 15 seconds. You see where each stock stands against the rest right now: the top gappers, the highest relative volume, the biggest movers from the open.
Choosing
Streaming window or Top List (Screener): when to use which
Use a Top List when you want a ranking: which stocks lead on one measure, and how that order changes.
Use a filters-only alert window when you want screener alerts when a stock meets your criteria, in a feed you can scroll back through, with a time stamp on each row.
Add an event alert, such as New High or Running Up Now, when you want to know the moment something happens to a stock that passes your filters. Then the window fires on the trade instead of on the Heartbeat.
Many traders run a Top List and a streaming window side by side with the same filters. For the event alerts momentum traders use, see the momentum stock scanner; for how fast alerts reach you, see how fast Trade Ideas is.
Setup
Build one in plain English or by hand
Settings
Ask the AI Assistant, in every TI Pro plan, for something like "stocks between $5 and $50 with relative volume above 2" and it builds the window. To do it by hand, open an alert window, choose Configure, set your filters on the Window Specific Filters tab, and leave Select Alerts empty so Heartbeat is used.
Scripting
Add your own filters with the Formula Editor
If a built-in filter doesn't measure what you want, the Formula Editor lets you build your own and use it like any other filter. It is in every TI Pro plan. See stock scanner scripting.
Testing
Test the idea
OddsMaker (TI Premium) can test an alert window, including a filters-only window, on Trade Ideas history with profit targets, stops, timed exits or the future close or open. See no-code backtesting.
Past results, including backtests, don't guarantee future results.

FAQ
Streaming stock screener FAQ
Change from the open, ranked in real time.What is a streaming stock screener?
A screener that pushes matching stocks to you as a live feed instead of waiting for you to refresh. In TI Pro, a filters-only alert window does this with the Heartbeat alert.
How do I get screener alerts when a stock meets my criteria?
Open an alert window, set your filters and select no alerts. TI Pro uses Heartbeat automatically and streams each stock that passes every filter.
How often does a stock appear?
By default each matching stock gets a Heartbeat row about every 5 minutes. The optional Minutes setting changes that.
What is the difference from a Top List (Screener)?
A Top List is a ranked board updated every 15 seconds. A filters-only alert window is a time-stamped feed of stocks meeting your criteria.
Can AI build the screener for me?
Yes. The AI Assistant, in every TI Pro plan, builds alert windows and Top Lists from plain English.
Can I use my own filters?
Yes. The Formula Editor, in every TI Pro plan, lets you build custom filters and use them in either window.
Is it real-time?
Yes. The window streams in real time, and adding an event alert such as New High makes it fire on the trade itself.
