> Why do you need price trackers for airbnb? It is not a superliquid market with daily price swings.

I dont know about AirBNB specifically, but I know local hotels I have dealt with can swing by 1000 bucks. Especially if theres a conference or something in town. Often it will swing back just before they risk the room going unoccupied. I have no idea if AirBNB allows similar behavior but I would be surprised if it didnt.
