Once a Bundle order has been placed, it cannot be modified. The only exception is if the order is still in pending status, in which case you may cancel it before execution.

If you are managing an auto-investment Bundle, you can make changes directly from the “Auto-invest” page for that Bundle.

Are there any risks to odd lot trading I should be aware of?

Yes. Odd lot trades generally come with lower liquidity, which means they may be executed at different prices or take longer to process compared to standard lot trades. In some cases, odd lots may also be filled at less favorable prices than standard board lot trades.
