Strange, mine shows them within a second of being posted, there's a trick to getting players to show faster than doing another search, when you see the players listed from your search, click on one of them and immediately back out, this refreshes the search without having to do it again, obviously you need to keep repeating this process until another is listed for the same or lower than the figure your filter is set at, don't click too fast though or you end up getting lockouts for appearing like a bot. I usually just wait a second before clicks instead of spamming it.
I've made about 100k alone buying Gimenez for anywhere between 500-2k below his going rate and immediately relisting over the past week while he's been needed for SBCs.
