Halt Scanner: Trade Alerts

About this app

Halt Scanner tells you the moment a NASDAQ stock halts, and the moment it resumes. Your broker's screen is slower. By the time a halt shows up there, the move has usually started without you. Built for traders who trade the halt and the resume. INSTANT ALERTS A push notification and an audio alert the second a halt hits the exchange feed. You do not have to be watching your screen to catch it. A LIVE COUNTDOWN TO THE REOPEN Every halted name carries a running timer to the resume, so you know exactly how much time you have to plan the entry. ONLY THE HALTS YOU ACTUALLY TRADE Filter by reason code (LUDP, T1, T12 and more), and by minimum price, volume, relative volume and float. Set it once and the names you would never touch stop waking your phone. THE NUMBERS THAT MATTER, ON EVERY ROW Price, volume, relative volume, float and the halt reason at a glance. Each halt also shows an up or down indicator, so you can see which way the stock was running when it tripped a volatility pause. SORT AND FILTER THE LIVE LIST Order halts by price, volume, float, relative volume or reason code. REAL TIME, ALL SESSION The list refreshes in the background through the trading day and stays steady while it updates. DARK AND LIGHT Follows your iOS appearance setting. SUBSCRIPTION Halt Scanner is a free download and starts with a 7-day free trial. After the trial, Premium is $9.99 per month or $59.99 per year.

Fixes from a trader's bug report — thank you, you know who you are: • Extended halts: when the exchange extends a pause past the standard 5 minutes, the countdown now rolls into the extension instead of stopping at zero. • The full-screen countdown now follows a stock onto its next halt when it halts again, with a badge showing which halt of the day it's on. • New in Settings: Compact display density — a tighter halt list so more fits on screen, built for narrow windows and smaller screens.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
