Effective 28 May 2024, the standard settlement cycle for transactions in U.S. securities will be shortened from two business days after the trade date (T+2) to one business day after trading (T+1)
For example: if you execute a trade on Monday (trade date), this transaction will be settled on Tuesday (assume Tuesday is not market holiday).
Please arrange enough funds / securities under the new settlement cycle to ensure the settlements can be done successfully.
