Custom Filters
- Thomas Timbul
Price Checker 2 allows you to discard items found during the analysis, which do not meet a set of criteria that you define.
For example, you might require that all items:
have never been sold by Amazon itself
are priced between $10 - $50
have at least 10 reviews
have a best seller rank (BSR) below a certain value
Any condition on any attribute that PC2 supports, including custom historical data
Filters are managed on the suitably named “Filters” screen:
You can turn them off temporarily, delete or change as needed, and as your analysis techniques evolve.
To create a custom filter
Click “Add Custom Filter”
Search for a data field or use the drop down to select
Choose an operator for the comparison.
Enter a comparison value
Items that match the criteria defined in this filter will be discarded

When does the comparison happen?
Whenever new data is available, your enabled filters are checked for a match and the item discarded immediately if possible. This ensures that the least required amount of information is downloaded, which ultimately speeds up your run.
Price Checker is smart enough to figure out when a filter can possibly compared. For example, it won’t try to act on a historical data filter when it hasn’t downloaded that information yet, or if historical data has been disabled for the current run.
