Response Fields

Top-level data (object, not array; single intraday snapshot only):

Field	Type	Description
capital_in_super	double	Inflow - super-large orders cumulative (in security's local currency).
capital_in_big	double	Inflow - large orders cumulative.
capital_in_mid	double	Inflow - medium orders cumulative.
capital_in_small	double	Inflow - small orders cumulative.
capital_out_super	double	Outflow - super-large orders cumulative.
capital_out_big	double	Outflow - large orders cumulative.
capital_out_mid	double	Outflow - medium orders cumulative.
capital_out_small	double	Outflow - small orders cumulative.
update_time	int64	Data update time (millisecond timestamp).

Net inflow = capital_in_* - capital_out_* (calculated by the caller as needed).

Supported Markets

Dimension	Supported	Not Supported / No Data Currently
Market (Stocks / ETFs)	HK · US · SH · SZ · SG · JP · CA · AU	MY · BJ (some codes parseable but no data currently)
Category	Stocks, ETFs	Indices, warrants, options, futures (valid symbol but no distribution data, returns no_data); cryptocurrencies (not supported)
Time Range	Intraday cumulative snapshot only	No time series; for intraday time series use Capital Flow (Intraday), for historical aggregation use Capital Flow (History)

When a symbol is valid but has no capital distribution data (indices / warrants / options / futures / suspended / pre-listing, etc.), the API returns ret_code=-10, error.code=no_data.

Error Codes

ret_code	error.code	Trigger Scenario	Suggested Handling
0	—	Success	Consume data directly
-3	invalid_parameter	symbol does not match MARKET.CODE format / required field missing	Correct parameters and retry
-7	invalid_symbol	Symbol format is valid but not found in security cache (does not exist / typo / unsupported market)	Verify symbol actually exists
-10	no_data	Symbol is valid but no capital distribution data currently (indices / warrants / options / futures / suspended / pre-listing / non-trading hours)	Treat as "no data" branch, no need to retry
-5	internal_error	Backend call failure / response conversion failure or other internal exceptions	Retry or escalate
