Why a currency trader watches B3

When São Paulo opens, liquidity in BRL rises; when it closes, it thins out. The hours when two big centres overlap — London with New York, Tokyo with Sydney — are when spreads are tightest and the large moves usually start. Book I of the ForeXistenZ trilogy teaches how to plan your day around these session hand-offs.
