Adding money to a Pie

Hi everyone. I would like to ask, when investing in any Pie, the new investment it will add like new order for every share or it will be calculated like a new average price for each share?
Thank you

If it is a stock within the pie that you are adding more to then it would show a new average price after you have bought the additional shares.
When you invest into the pie you can click the drop down menu just above the amount you are investing and it will give you 3 options as to how you want the money invested and how much will go into each piece of the pie.

Thanks for response.
Yes I knew about the 3 options, it means the fund added to the pie its a new average for each stock as well.
