Member Function Documentation

load_csv()

std::optional< std::vector< OHLCV > > srfm::core::DataLoader::load_csv ( const std::string &  filepath )

staticnoexcept

Load OHLCV bars from a CSV file on disk.

Arguments

• filepath — Path to a CSV file with header row (timestamp, open, high, low, close, volume)

Returns

• nullopt if the file cannot be opened
• Empty vector if the file has a header but no valid data rows
• Vector of parsed bars, skipping any malformed or non-finite rows

Definition at line 193 of file data_loader.cpp.

parse_csv_string()

std::vector< OHLCV > srfm::core::DataLoader::parse_csv_string ( const std::string &  csv_content )

staticnoexcept

Parse OHLCV bars from a CSV-formatted string (useful for testing).

Same format as load_csv — first line is treated as a header.

Returns

Parsed bars. Never returns nullopt; returns empty vector on completely empty or header-only input.

Definition at line 161 of file data_loader.cpp.

validate_bar()

bool srfm::core::DataLoader::validate_bar ( const OHLCV &  bar )

staticnoexcept

Validate a single OHLCV bar.

A bar is valid if:

• All fields are finite
• low <= open, close <= high
• high >= low
• volume >= 0
