Where the number comes from
The BTC to USD page requests CoinGecko pricing for bitcoin quoted in usd, then multiplies by your input amount. Server data revalidates about every minute; the widget can refresh while the tab stays open.
If the API is briefly unavailable, retry. A cached value may still display.
Reading the 7-day chart
The chart shows recent mid-market context for the same pair so you can see whether today’s print sits near recent highs or lows. It is not a tradingView full order-book chart.
Percentage change on the chart is first-to-last sample over the window, not realized P&L on your wallet.
