The mutual fund values on your account curve are calculated as per T-2 days, while the mutual fund holdings on the donut chart display T-1 day values. This difference occurs because the account curve displays values according to the holdings file that Zerodha receives from the depository, which provides a comprehensive overview of your portfolio. The donut chart values are directly connected to the daily P&L processes conducted on a T-1 day basis for mutual funds.
Example scenario
The account value curve on 18th July displays the values as of T-1 day, i.e. 16th July, since 17th July was a trading holiday. Here, your mutual fund holdings values are displayed as per T-2 days, i.e. 15th July.
The mutual fund value on the donut chart on 18th July is displayed according to the T-1 day value, which is 16th July.
