Currencies and precision
Ordinary price responses retain market_currency_code; changing a dashboard preference does not convert these API quotes.
Keep the currency with the amount
Ordinary price responses retain market_currency_code; changing a dashboard preference does not convert these API quotes. Use currencies to inspect the official currency catalogue and its rate fields.
Money and rates are decimal strings. Use a decimal library for calculations and round only at a defined boundary. Do not parse money into binary floating-point and assume exact results.
Different currency contexts
CSCP valuation is in CNY. Fee processing computes CNY purchase, sale and payout amounts internally, while platform configuration describes its own home currency. These are different contexts; the public price schema does not expose all internal fee amounts.
When converting a quote yourself, keep the original amount and currency, record the rate you used and label the result as your conversion. Exchange rates and marketplace fees can change independently.
