Historical data is split-adjusted.
1 Trade Date is calculated from the Settlement Date.
2 Fails to deliver on a given day are a CUMULATIVE number of all fails outstanding until that day, plus new fails that occur that day, less fails that settle that day. A dash (—) indicates no FTDs were reported that day. It’s been shown that the SEC withholds the FTD report for two weeks, and there are often high-volume days with no reported FTDs, so it’s unclear if missing days truly indicate 0 FTDs.
3 Closing price on the Trade Date. The FTD file contains the closing price on the day previous to settlement.
4 As of May 28, 2024, the standard for settlement is next business day after a trade (T+1B). Before that, it was trade date plus two business days (T+2B).
5 RegSHO IV. 3. A broker-dealer has up to 35 calendar days following the trade date to close out the failure to deliver position by purchasing securities of like kind and quantity. Analysis of the T+35 cycle.
