Get the max for a calculated measure based on top 10 products

[Anonymous]

Hello,

I have a measure that ranks my products based on sales 

Product Rank =

VAR Ranking =

    RANKX(

        FILTER(

            ALLSELECTED(Product[Product]),

            NOT(ISBLANK(CALCULATE(SUM(Sales[Quantity]))))

        ),

        CALCULATE(SUM(Sales[Quantity]))

    )

RETURN

    Ranking

Another measure that gets the maximum of a calculated measure 

MAXX(Sales, [Declared Stock]) however this measure gets the maximum value of declared in the whole dataset.

I would like to get the maximum but only within the top 10 products, how can I achieve that?

Thank you!
