Definition
What is a day-trading scanner?
A day-trading scanner monitors intraday market data for conditions relevant to a defined short-term workflow. Its job is to reduce search work and timestamp measurable changes—not to decide whether, when, or how a security should be traded.
Who it is for
Built for active traders who verify the evidence.
TraderBase is built for active traders who use scanners, alerts, charts, watchlists, and bounded Agent explanations as one evidence workflow and who define risk independently of the software.
How it works
From changing data to a focused review.
- 1Select a market universe and scanner rules that match a documented setup.
- 2Receive current-state results or distinct timestamped alerts as supported conditions qualify.
- 3Validate price structure, participation, spread, liquidity, catalyst, filings, offerings, and halt context.
- 4Use bounded Agent explanations to organize the available evidence while keeping the decision independent.

Intraday event detection
Monitor implemented price, volume, VWAP, breakout, news, earnings, and halt conditions.
Focused ticker context
Move from a scanner row to linked multi-interval charts and available market evidence.
Alerts and watchlists
Monitor selected conditions and symbols without repeatedly refreshing an isolated screener.
Bounded explanations
Ask about scanner events and linked context without turning explanation into personalized advice.
TraderBase approach
What makes TraderBase different?
TraderBase is a market-information platform, not a broker or personalized signal service. It does not route live orders, hold assets, promise outcomes, or replace independent risk management.
Common questions
Day-trading scanner FAQ
What scanners are useful for day trading?
Common workflows monitor premarket gaps, momentum, high-of-day, recent and relative volume, VWAP, breakouts, catalysts, earnings, and halts. Use only rules that fit a defined process and available data.
Does TraderBase execute trades?
No. TraderBase does not route live orders, hold brokerage assets, or manage positions. Scanner and Agent output is market information for the user to evaluate.
Can a day-trading scanner remove risk?
No. Scanners can reduce search time, but market, liquidity, execution, halt, and loss risk remain. A qualifying event can fail immediately.
