52-Week High and Low Stock Alerts Including Extended Hours
Track new 52-week stock highs and lows across premarket, regular, and postmarket sessions with ChartsWatcher’s extended-hours high and low alerts.
Understand the trigger
What is 52 Week High/Low (pre/post-market)?
This alert identifies a stock creating a new 52-week high or low, including prices reached in extended hours. Select High or Low to choose the direction of the new annual-range extreme you want to monitor. ChartsWatcher calculates the event during premarket, the regular session, and postmarket. Its year-long reference differs from a daily high or low and from the separate five-year high alert.
An illustrative example
52 Week High/Low (pre/post-market) in practice
Imagine a company releases news after the close and its stock trades above the highest price seen within the prior 52 weeks. The extended-hours variant is designed to include that event. A regular-session-only review would miss the timing and liquidity context of the postmarket move.
Make it part of your workflow
Catch the event. Keep the context.
Use ChartsWatcher to surface annual-range milestones without restricting your review to the opening bell through the close. When an alert appears, compare the new high or low with the longer chart history and inspect the current session. Adding volume and price filters can keep the resulting stock universe aligned with your research scope.
ChartsWatcher brings your chosen alert types and filters into the same alert window. Add the data columns you want to see, then use the connected chart and news tools to explore a matching symbol.
