It’s the type of thing you work on long term to correct for inaccurate predictions, so you start with larger margins than needed and then narrow them down as you gather against the predicted outcomes. I never cared enough to collect the data to see if it’s improving or not. You would need a few T variables for time in the calc too to deal with the slope of the curve over time too. Maybe the sharper the demand spike the sharper the rise…? That type of thing…
Have the price corridors ever been explained in detail? Like the actual mechanics of how the corridor moves?
I assumed it based itself off average buy and sell offers. Big jumps could happen organically when overly optimistic offers expire. Especially when you have people playing the market and buying/selling lots of a single item.
Here’s what PS4 looks like with no price corridors:
I don’t think the devs are doing shenanigans with price corridors on PC. I just think they created some system to try to solve the market fraud problem, but didn’t do a great job. Hopefully it at least managed to fix the fraud problem, because it seems to really make the PC market weird.
