Korean insider transactions for a listed KR company, from DART's 임원ㆍ주요주주 특정증권등 소유상황보고서 (elestock) — the Korean equivalent of SEC Form 4. Includes a buy-vs-sell summary and an optional buy/sell filter.
Not this tool for: US insiders (get_edgar_insider_trades) or institutional managers, which are a different kind of holder entirely (get_edgar_13f).
Buy vs sell is the SIGN of the reported share change (증감수): positive = 취득 (acquire / buy), negative = 처분 (dispose / sell). Insider BUYING is a stronger sentiment signal.
Args:
- company (required): KR 6-digit stock code (e.g. '005930'), company name, or 8-digit DART corp_code
- limit: number of most-recent reports to return, 1-100 (default 20)
- tx_type: 'all' (default) | 'buy' (share change > 0) | 'sell' (share change < 0)
- response_format: 'markdown' (default) or 'json'
Returns: {company:{corp_code, corp_name}, tx_type, summary:{buys:{count,shares}, sells:{count,shares}}, count, trades:[{filedAt, reporter, position, registered_exec, major_shareholder, change, shares_after, change_rate}], notes}. summary totals cover the whole fetched set regardless of the filter.
Important: unlike US Form 4, the KR report has NO transaction price — only share counts (no value). Reports are filed within ~5 business days.
Examples:
- "삼성전자 임원 매수" -> {company:'005930', tx_type:'buy'}
- "SK하이닉스 내부자 매도 최근" -> {company:'000660', tx_type:'sell'}
Use when: monitoring KR officer / major-shareholder buy/sell activity. For US insiders use get_edgar_insider_trades. For institutional holdings use get_edgar_13f.
Errors: unknown company -> use search_dart_company; a filter with no matches returns count 0 (not an error).
