How the Trade Ideas Stock Screener works

A stock screener is your fantasy football lineup. You set it before the game, and you keep a board of who qualifies.

In Trade Ideas that board is the Top List. It is a live list of stocks that meet your criteria. Top Lists update every 15 seconds. It is not a spreadsheet you rebuild by hand.

New to trading? You don't have to build a Top List to start. The Channel Bar's ready-made, themed channels come with TI Pro on every plan. Click one and live Top Lists open. See Trade Ideas for beginners.

The Top List updates every 15 seconds. If you are okay with static non-refreshing data, Trade Ideas is probably not your best choice.

Trade Ideas Stock Screener vs Stock Scanner

The same English ask, the same configuration screen, and the same Formula Editor filters that build an alert can build a top list. A scanner reports the play. A screener shows the lineup.

See how Top Lists compare with other screeners and scanners in the best stock scanners of 2026.

Trade Ideas Stock Screener questions

What is a stock screener?

A screener is a lineup of stocks that meet your criteria. You set it before the action, or you keep it as a live board. Trade Ideas calls that board the Top List.

Does Trade Ideas have a real-time stock screener?

Yes. Trade Ideas Top Lists are the real-time stock screener. They show the stocks that qualify right now and update every 15 seconds.

What is the difference between a stock screener and a stock scanner?

A screener is the lineup: it ranks the stocks that meet your criteria right now. A scanner is the play, reported the moment it happens. Trade Ideas has both. The Top List is the screener. Streaming Alerts are the scanner, with 310 real-time alerts. See the Trade Ideas stock scanner.

How often does the Trade Ideas stock screener update?

Every 15 seconds. Top Lists re-rank as the market moves, premarket and after hours included.

What screener settings do day traders use for premarket gappers and high relative volume?

A common start is a gap filter with a minimum percent gap, a relative volume filter well above 1, a minimum price and a minimum average volume, sorted on gap or on relative volume. The Channel Bar also has ready-made premarket and momentum Top Lists you can open and adjust.

Can I get alerts from my stock screener?

Pair it with Streaming Alerts. The Top List shows who qualifies now; the stock scanner tells you the moment a stock does something, so a screener with alerts is two windows side by side.

Is there a free way to try a real-time stock screener?

Yes. Open a free account to try the Web Dashboard, which includes Top Lists.

Can I build a top list in English?

Yes. Ask Holly in plain English and it builds top lists and alerts. Custom formulas are still written in the Formula Editor.

How do I screen for stocks near 52-week highs?

Use the Position in Range (1 year) filter (RY). It shows where the price sits inside the past year's range, so you can set a minimum to keep only stocks trading near their 52-week high.

Can I screen for unusual options activity?

Yes. The Options Volume Today (%), Call Volume Today and Put Volume Today filters screen for heavy options volume. Trade Ideas also monitors unusual options activity across all stocks, with a dedicated channel in both TI Pro and the Web Dashboard.

How do I screen for low float, high short interest stocks?

Combine the Float filter, with a maximum float, and the Short Float filter, with a minimum short float, in the same Top List.
