You can only place another order after your Fund Portfolio order has executed — and that subsequent order won’t be executed until the following day’s trading window.
With a Fund Portfolio order (or a Sell Portfolio or Rebalance Portfolio order), trades are created for your portfolio based on the target weights you set.
Where your portfolio has moved away from its target weights, these trades are calculated to bring it back towards your chosen allocation — helping you stick to your investment strategy.
Given this, when you place a Fund Portfolio order (or a Sell Portfolio or Rebalance Portfolio order) we don’t accept further orders until the initial order has executed.
You should be able to place your next order from about 6pm after the day’s trading window has closed.
However, if your initial order is simply to invest in a single ETF (a single-stock order rather than a portfolio order) you can still place orders for other ETFs for processing in the same day’s trading window.
But you can’t add a portfolio order to a single-stock order, or place two single-stock orders for the same ETF.
