The rule, adopted in 2023 alongside the transition to a T+1 settlement cycle, requires central matching service providers to establish, implement, maintain, and enforce written policies and procedures reasonably designed to facilitate straight-through processing of securities transactions. The dataset includes all Form 17AD-27 and Form 17AD-27/A filings submitted to EDGAR from February 2025 to present. Form 17AD-27/A filings represent amendments to previously filed annual reports. For each accession number, a metadata file and all documents in the original EDGAR submission are included except image files; this covers the primary report document, Inline XBRL data, and any accompanying exhibits. Each filing typically contains a summary of the filer's straight-through processing policies and procedures, a qualitative description of progress in advancing automated transaction processing, quantitative data on trades, allocations, confirmations, affirmations, and cancellations broken down by month, service type, asset class, and user category, and a description of planned initiatives to further automate securities transaction processing.","updatedAt":"2026-04-16T09:02:15.462Z","earliestSampleDate":"2025-02-01","totalRecords":3,"totalSize":158861,"formTypes":["17AD-27","17AD-27/A"],"containerFormat":"ZIP","fileTypes":["HTML","JSON"],"containers":[{"downloadUrl":"https://api.sec-api.io/datasets/form-17ad27-files/2026/2026-02.zip","key":"2026/2026-02.zip","size":56913,"records":1,"updatedAt":"2026-04-16T09:02:14.951Z"},{"downloadUrl":"https://api.sec-api.io/datasets/form-17ad27-files/2025/2025-09.zip","key":"2025/2025-09.zip","size":54913,"records":1,"updatedAt":"2026-04-16T09:02:14.957Z"},{"downloadUrl":"https://api.sec-api.io/datasets/form-17ad27-files/2025/2025-02.zip","key":"2025/2025-02.zip","size":47035,"records":1,"updatedAt":"2026-04-16T09:02:15.462Z"}]}
