A Failure to deliver also known as fails-to-deliver or FTD occurs when a buyer or seller is unable to meet his trading obligations.
FTDs for US listed companies are reported to the SEC and published twice a month.
Therefore there is a certain delay between the reporting and the publishing of the data.
