Exchange rate history is here
You can now open a dedicated Exchange rate history page from the sidebar and explore USD/BRL over time—powered by the same poll snapshots your exchange service stores in Redis.
Where to find it
After you sign in, use Exchange rate history in the left sidebar (between Cash Flow and Household). The chart loads from `exchange:poll_history` when Upstash Redis is configured for this app.
Ranges & tooltips
Pick last 7 days, 30 days, or 90 days for intraday-style history from Redis (downsampled for speed). Year to date loads daily closing USD/BRL from your exchange service `GET /api/exchange/usd-brl/ytd`. Hover the chart for timestamps and BRL-per-USD values.
