The Best Premarket Scanners in 2026

What a premarket scanner is for

The right tool depends on how you trade. Some traders need exact rules. Others care most about breaking news. Some want AI to surface ideas they did not define.

How we compared

Before the open, one question matters: which few stocks deserve your attention? We asked all 8 tools the same 8 questions, and each answer fills a column of the table.

• What it is: Event scanner, screener or news service.
• Real-time data: Does it track extended-hours prints, and on which plan?
• Scans and alerts: Can it filter on gap, premarket volume and float, then push the matches?
• Backtesting: Can you test a gap setup on history before you trade it?
• AI: How the company describes its AI.
• Beginner-friendly: Presets, a live routine to watch, a intro period.
• Price: What the company's site charges.
• Best for: The morning routine it suits.

The 8 best premarket scanners

1. 1. Trade Ideas

   Trade Ideas gives you two ways into the premarket. Your own rules catch the gappers you planned for. Holly, the Trade Ideas AI, surfaces the ones you did not think to look for.

   Settings

   From the gap to the open. Once the bell rings, the gap plan turns into opening range alerts: breakouts and breakdowns measured over the first 1, 2, 5, 10, 15, 30 or 60 minutes, such as the 1-minute breakout and the 5-minute breakdown, and the bullish opening power bar fires above a strong first 5-minute candle. They come from 308 alerts and 249 filters documented in our help. Any alert can be paired with filters such as gap, premarket volume and float, each with a min and max, and 191 alerts add their own setting, like the minimum number of days on Pre-market Highs. That makes the possible morning scans effectively unlimited.

   See the gap form. Streaming Alerts can fire on every trade before the bell. That can be multiple times per second. A premarket high or premarket low alert fires when that print happens. You watch the level being set, not the recap.

   Key point

   Rank what is real. Sort gappers with the Gap (%) filter, then check Volume Today, which counts shares from the premarket on. Add float and position in premarket range. That separates a real move from a thin one.

   Key point

   Start from a channel. The Channel Bar comes with TI Pro on every plan. Open a ready-made channel, or type your morning rules into AI Assistant, also in every TI Pro plan, and it builds the scan.

   Ideas you did not define. On TI Premium, Holly AI Signals fire intraday with an entry and a stop to manage risk. They are designed for large, long-term potential winners, and you choose to exit the same day or hold. OddsMaker, also on TI Premium, tests a gap setup on Trade Ideas history before you trade it, with no code.

   Key point

   Watch a routine live. The free Trading Room with mentor Barrie Einarson opens at 8:00 a.m. ET. You see a morning list get built and cut before the bell.

   Key point

   Price: TI Standard lists at $127 monthly and $1,068 annually. TI Premium costs $254 a month or $2,136 a year.

   Worth knowing: Trade Ideas covers U.S.-listed stocks. Its options data is limited to volume-based filters. Premarket traders on a Mac can run TI Pro through Parallels; on a PC it installs directly. Any browser can open the web Dashboard with no download, though premarket Streaming Alerts need TI Pro. Open a free account to look at the Dashboard before you subscribe.

   Trader tip

   Best for: Traders who want strict premarket rules and an AI source of ideas side by side, and new traders who want the premium experience.

Ten things to look for in a premarket scanner

1. Premarket data. Confirm the tool processes extended-hours prints. A scanner built for the regular session may not help at 8:00 a.m.
2. Update speed. A list you refresh does a different job from a scanner that watches for new events.
3. Premarket volume. A big percentage gap can rest on very few shares. Volume shows whether real participation is behind the move.
4. Gap and price filters. They drop stocks outside your range. In Trade Ideas, use the Gap (%) and Price filters.
5. Float. Low-float stocks can behave very differently from liquid large caps.
6. Catalyst. Ask why the stock is moving. Earnings or company news can change how you read the move.
7. Liquidity and spreads. FINRA warns that extended hours can bring lower liquidity, higher volatility and wider spreads. A 20% mover is often not easy to trade.
8. Alerts. If your setup depends on events, alerts may matter more than the number of filters.
9. Testing and practice. A scanner can show many plausible setups. Backtesting and paper trading show how your rules behaved before real money is involved.
10. Your broker. The SEC notes that extended-hours access varies by brokerage firm. Make sure the scanner fits how you place orders.

Rule-based vs AI premarket scanning

Neither is better in every case. They solve different parts of the problem.

Competitor prices and features checked October 12, 2026.

Rules enforce your must-haves. AI adds another source of ideas. Trade Ideas gives you both: Streaming Alerts and Top Lists (Screeners) for rules, and Holly for AI.

A six-step premarket routine without a 30-stock watch list

1. Start broad. Find stocks with real overnight activity. The biggest percentage gainer is often not the best idea.
2. Cut what doesn't fit. Apply your price, volume, gap, float and liquidity rules in the same order every day.
3. Find the reason. A move after an earnings surprise is different from a move with no clear news.
4. Mark the chart. Note the prior close, the premarket high and low, and the prior day's high and low. The Below Pre-Market High filter shows how close price is to that level.
5. Shrink the list. A handful of names you understand beats 25 tickers on a screen.
6. Wait for confirmation. Showing up on a scanner only means a stock met your conditions. You still decide whether to trade it.

Which premarket scanner fits your style

Do you need to pay for a premarket scanner?

Not every time. A free screener can be enough to check movers and build a basic morning list.

Paying makes sense when your process needs streaming data, event alerts, detailed filters, news, testing or AI ideas. Base the choice on your workflow. Paid software does not by itself produce better trades.

Who Trade Ideas is not for

Trade Ideas earns its price in the minutes around the open. Skip it in these cases.

• You plan every trade the night before. A free end-of-day screen may do the job.
• You trade only crypto, forex or futures. Trade Ideas covers U.S.-listed stocks.
• A monthly fee this size would be a big bite of your account. Try free tools and paper trading for now.
