Just got a PM telling me that I passed the market graduation test (That means I got the achievement). Finally I took a while to be more experienced in the market this time, because I took the test before I joined secret and flunked it 2 times, this was my last chance and went great
Achieved by 45 players.
Congrats, you just learned the basics of playing the tori-market! Buy low, sell high, get rich! How to get it: Pass the market graduation test.
