The list on Inara in my experience is wrong 95% of the time. I just made a list of a few good known spots and use those.
As Bob says futher up the thread, if you stick with the stations that only have a single economy (not a single trader type; that was my mistake) it's a lot more reliable. I hit four this morning and all were exactly as listed.
Once we've all flown around for a couple of weeks and built up our own histories the galactic map filters should be more useful.
One other advantage of INARA is that you can see immediately if the station is a bazillion light seconds from the entry point without having to drill down into a system map.
Aside: from a lore perspective the speed with which these traders switch specialities when the economy flips is yet another bit of
ED galaxy silliness. "Right, lads, I've just been informed that the station had a higher turnover of extracted goods than refined materials in the last 24 hours, so you know the drill. Strip out all of these manufactured material racks, pretend like they were never here, and replace them with data servers. But don't forget to keep the materials handy in case we need to swap it all back again tomorrow, eh?"
