Money Flow (Stock / ETF / Sector / Market)

Retrieve multi-granularity secondary-market order-flow data for China-listed securities. scope=stock: individual stock fund flow over a date range — close price, change pct, full-day/open/close main net inflow amounts and amount ratios, super-large/large/medium/small active buy amounts, DDE net vol, 5/10/20-day DDE, turnover (17 indicators, date_sequence endpoint). scope=etf: individual exchange-traded fund flow by ETF code over a date range, using the same 17 secondary-market indicators; this is trading/order flow, not ETF creation/redemption flow. Some open/close or ratio indicators may be null for an ETF when iFinD does not publish that field; callers must use the returned values. scope=sector: sector index fund flow on a single date — sector name/category/type, change pct, main net inflow, super-large/large active buy amounts, rise/fall/total stock counts (11 indicators, basic_data_service endpoint). scope=market: market index fund flow over a date range — main net inflow, super-large/large/medium/small active buy amounts, total turnover, inflow rate (7 indicators, date_sequence endpoint).
