That "article" is some numbskull's comments on the proposed changes to 15c-211 a couple years ago and is a bunch of BS. Those notes are just wrong, if a share is not delivered to the buyer within 3 days, it is an FTD, period. There are other deadlines leading up to someone being forced to buy a share to cover the transaction, but it will be recorded as an FTD. It is simply fodder for the pumper con artists to foist on their marks and divert their attention away from the profit taking that is going on when the pumpers sell their stock.
