When opening a Macquarie Online Trading (MOT) account, it will be linked to a Macquarie Cash Management Account (CMA) for the purpose of settling trades.
Each MOT account needs to be linked to its own Macquarie CMA. You can have multiple MOT accounts in the same name, but they need to each have their own Macquarie CMA.
When you want to buy an asset with the MOT account, there’s no need to transfer money from the CMA to the MOT account. Once the trade is placed, the system will pull the required money from the CMA to fund the MOT account.
