Date: 2026-11-03. State: Accepted by user answer; implementation pending.
Context#
In round 1, Q2, the user chose both markets.
Decision#
Cover B3 and US stocks, with instrument, calendar, currency and adapter contracts per market. The broker and data source have not been chosen.
Alternatives#
One market only was recommended and not chosen. Do not silently reduce the MVP to the US.
Consequences#
More integrations and datasets; BRL and USD separated; backtest/paper may have incremental implementations, with explicit modes. B3 data access still needs to be resolved.
Review trigger#
Explicit scope change or proven infeasibility discussed with the user.
