"#% reduced Attack and Cast Speed" doesnt exist as a filter, on trade website

Item - Kitoko's CurrentJewelled Gloves, has a stat "reduced Attack and Cast Speed". i was trying to find one with 11-12% maximum but because there is no filter, it was kinda annoying.

This is usually a confusing issue on the trade site. Often times "increased X" and "reduced X" are the same modifier, but with positive and negative values respectfully.

You might find success looking for "increased Attack and Cast Speed" and then setting the maximum value to your desired negative number of -11 or -12
