look at the blue line, except that 1.00 is around 1000 fgs on first day, and 0.00 is std price
weirdly, the slope doesnt really change much based on the league quality, because a shit league like bestiary will have less buyers, but also less sellers than something much better like this league for example
basically first day 1000 fgs, 10 days after that 500, then 10 days after 250 etc
! rough estimate ofc, havent played for a while, but the graph always looks like that!
