Prices and thresholds
Distinguish any change, a decrease and crossing below an amount. Test equal values and the exact threshold as well as an obvious match.
KNOW WHEN THE RULE MATCHES
Would this change trigger your alert?
Try example before-and-after values against the rule you are configuring. PageFluxer explains the match, so you can check a price threshold, phrase, stock transition or new-item rule before relying on it.

Price falls below $100
- 120 → 95
- Matches: the price crosses below your threshold.
- 95 → 90
- Does not match this rule: the price was already below $100.
- 120 → 100
- Does not match: equal to the threshold is not below it.
Illustrative numeric inputs. Choose a price-drop rule instead when every decrease should count.
Make the condition easy to explain.
Text, stock and new links
Check a phrase appearing or disappearing, a stock transition or a newly discovered URL. Optional previously seen URLs let you test whether an item is actually new.
Supported combined conditions
Test Any or All conditions against the same example capture. A match still needs a successful real capture and your enabled delivery settings.
FROM QUESTION TO CAPTURED CONTEXT
A practical way to start.
Configure the real rule
Choose the goal, targets and conditions in monitor setup or the available rule controls.
Enter example captures
Try a matching pair and an edge case. For a new-item rule, include previously seen URLs when they matter.
Read the explanation and preview
Check which condition matched, then run the real capture preview before saving. Example values cannot validate a selector or website access.
FIT IT TO YOUR WATCH LIST
Available with ordinary monitoring.
The tester is included across plans and does not use a check allowance or AI Credits. The actual monitor still follows its normal plan and source limits.
Use it for supported Cloud and Local rule settings in the web app. It does not change the rules understood by existing extensions.

Does a matching example send an alert?
No. It only evaluates the supplied example values and explains the result. Use notification test controls separately when you want to check delivery.
Why does a second price drop below my threshold not match?
A price-below rule detects a crossing from at or above the threshold to below it. Choose a price-drop rule if every captured decrease should match.
Can this prove the page will be captured correctly?
No. Confirm extraction, currency, target identity and page access in a fresh preview. Your first successful capture establishes the baseline for subsequent comparisons.

Confirm the capture where your monitor will run, then choose the settings that match your goal.
