from FID ~~~~ Starting September 5, 2017, the time between trade date and settlement date will shorten from three business days (known as T+3) to two business days (T+2). The shortened settlement cycle will affect most common security types, including equities, ETFs, and corporate and municipal bonds. Margin customers will be required to meet House and Fed calls within 4 business days from the trade date (T+4) rather than the current five days
