Best small cap scanner for day trading, compared on float, halts and price
The best small cap scanner for day trading filters by float and relative volume, flags halts as they print, and alerts you before the move is over. Edge To Trade, Scanz, Trade Ideas and Warrior's Day Trade Dash all cover that from $49 to $247 per month. DayTradingSoftware covers the scan, the alerts and the halts from $49 per month, or $24 billed yearly, and adds a journal that records the scan state of every trade.
What a small cap scanner has to do that a normal screener does not
Small caps move on thin supply. A stock with 8 million shares floating can go 80% on 400,000 shares of volume, and a scanner that refreshes every minute shows you the move after it happened. Five things separate a real small cap scanner from a general screener.
- Streaming data, not a page you refresh. Rows should appear and re-rank as the tape prints.
- Float and relative volume as filters, not columns you sort by hand. See the low float scanner page for starting values.
- Premarket coverage from 4:00 ET, because most small cap gaps are decided before the open. The premarket gap scanner page covers that setup.
- Halt and resume alerts. A halt is the most expensive surprise in small caps, and the halt scanner page shows what to filter.
- Alerts on a phone or second screen, so you are not watching one list for four hours.
Everything else, such as AI tags, social feeds and chat rooms, is nice to have. If a tool does those five things well, it can do the job.
Small cap scanners compared on price and fit
Prices are monthly list prices from each vendor, checked in October 2026. Vendors change plans often, so confirm on the day you buy.
| Scanner | Monthly price | Small cap strengths | Best for |
|---|---|---|---|
| DayTradingSoftware | $49 Starter, $149 Pro, yearly from $24 | Real-time gap, float, RVOL filters, halt alerts, journal with scan state | Manual traders who want scan and review in one tool |
| Edge To Trade | $49 Basic, $89 Pro, $149 Pro+ | 300 plus filters, news, daily audited float, dilution tracking from Pro | Traders who research the share structure before entry |
| Scanz | $89 Starter, $199 Pro | News and SEC filing scans, desktop app on Pro | Headline and filing driven traders |
| Trade Ideas | $127 Standard, $254 Premium | Prebuilt channels, AI signals on Premium | Traders who want ready-made scans |
| Day Trade Dash | $147 to $247 by simulator and membership | Scanners, news and a simulator in the Warrior ecosystem | Warrior Trading students |
The cheapest rows are not automatically the best. If you check dilution before every trade, Edge To Trade Pro at $89 is built for that and we do not offer it. If a headline decides your entries, Scanz or Edge To Trade earn their price. If your edge is the gap, the float and the volume, paying for features you never open is wasted money.
Which scanner fits which trader
A trader with a small account and one setup does not need a $200 platform. A scanner with five saved lists and 50 alerts covers a gap and go routine with room to spare, and at $24 to $49 per month the subscription is a rounding error against one stop-out.
A trader who has done 300 trades and still cannot say which setup pays needs measurement more than another scan. That is the case for pairing the scanner with a trading journal: the journal stores gap %, RVOL and float with each fill, so after enough trades the data tells you which condition to scan for.
A trader who trades news catalysts should pick a scanner with news built in and accept the higher price. A prop desk that wants several traders on shared scans should look at the Desk plan with 10 seats.
Four mistakes when picking a small cap scanner
- Buying for the demo. Every vendor demo shows a perfect runner. Ask what the list looked like at 8:00 ET on a boring Tuesday.
- Ignoring the plan limits. Entry plans often cap you at one running scan, which is not enough when you want gappers, low float and halts at once.
- Paying for a course you will not finish. Bundled scanners cost $147 or more per month, and part of that is education.
- Skipping the review. Without a record of fills tied to scan conditions, you will keep scanning for the same setups that lose money.
Before you commit to any scanner, research the stock the scanner finds. A tool such as AI stock research can turn a ticker into a structured company summary in a minute, which helps when a scan row has no news attached.
