How the Pre-Market Movers scanner works

By the time the opening bell rings, the day's biggest catalysts have already played out in pre-market trading. Earnings reactions, FDA decisions, M&A news, analyst actions, geopolitical surprises — they all show up first in the pre-market session, often hours before regular hours open. Our pre-market scanner runs at 8:30 AM ET on a real-time market data feed, pulling a single live snapshot of every US ticker and surfacing the names that are gapping or moving 2%+ from yesterday's close on real volume. It's the fastest way to know what's in play before the bell — without paying for a Bloomberg terminal.

What we analyze

Live snapshot for every US ticker (one real-time data feed call)
Open vs prior close (gap percentage)
Last-trade price vs prior close (total change)
Today's session volume vs prior-day volume (pre-market volume ratio)
Direction (Up vs Down)
$1 minimum price and 50K minimum prior-day volume

How our grading system works

For pre-market movers, an A+ grade means a 15%+ total change with absolute volume above 5M shares and pre-market volume already at 50%+ of yesterday's full session. A grades require 10%+ moves with strong volume. B+ requires 5%+ moves with confirming volume. B meets the 2% minimum move. This is not a prediction of future price movement — it is a way to prioritize which charts deserve your attention first.

A+
Textbook setup with strong confluence
A
High-quality setup worth watching
B+
Decent setup with some reservations
B
Pattern detected but lower conviction
