B3 (Brasil Bolsa Balcão)

B3 (Brasil Bolsa Balcão) is Brazil's main exchange and the center of price discovery for Brazilian equities, index products, and many domestic fixed-income instruments. For global traders, B3 is often a "risk-on / risk-off" proxy for Latin America—sensitive to commodities, local rates, and country-specific political headlines.

Because international participation can flow through ETFs, ADRs, and derivatives, you'll often see Brazilian risk express itself across multiple venues. That makes a clean "is the local market open?" view especially useful: it helps you interpret whether a move is happening in the core cash session (stronger signal) or during quieter hours (often thinner liquidity).

Trading Nuances: Emerging-market sessions can be headline-driven; price can react sharply to policy comments, fiscal news, and inflation surprises. Liquidity is usually best during the main cash session; outside it, spreads can widen and moves can be noisier. Keep an eye on U.S. market direction: global flows can amplify moves in Brazil during the Americas overlap.
