Change from After-Hours Close Stock Screener
Compare current stock prices with the previous after-hours close in ChartsWatcher. Screen dollar or percentage moves from that extended-hours anchor.
Understand the metric
What is Change from after-hours close?
This filter uses the previous trading session’s after-hours closing price as its reference. It measures the difference from that price to the current price, with dollar and percentage options. The reference differs from the regular-session close, so it can help separate an earlier after-hours move from the movement that developed after the extended session ended.
An illustrative example
Change from after-hours close in practice
Imagine a regular close of $20, a previous after-hours close of $22 and a current price of $23. The move from the after-hours close is $1, or about 4.55%. Measuring from the regular close would instead show $3, or 15%.
Make it part of your workflow
A more deliberate stock screen.
Create a ChartsWatcher screen that follows movement beyond the previous extended-session finish. Add premarket volume and recent-news filters when reviewing overnight activity, then compare the chart’s session boundaries so the price anchor is clear before interpreting the size of the move.
ChartsWatcher lets you combine this filter with other criteria in a toplist and rank the results by the columns you care about. Keep the shortlist beside charts, stock news, and watchlists in your own layout.
