    HI wooand

     

    Try this formula

     

    Formula =
VAR FirstNonBlankTradeStartTime =
    CALCULATE ( FIRSTNONBLANK ( ALL ( Results[Trade Start Time] ), TRUE () ) )
RETURN
    CALCULATE (
        FIRSTNONBLANK ( Results[Dealt Rate], 1 ),
        FILTER (
            ALL ( Results ),
            Results[Trade Start Time] = FirstNonBlankTradeStartTime
        )
    )

Can you post the DAX for your formula? And could you post some sample data? Are you looking for the firstnonblank for each Deal Reference?

    Sure, here's a snip of the Excel data file as it stands:

     

     

    It carries on in the same vein for several thousand lines.

     

    By using = CALCULATE(FIRSTNONBLANK(Results[Dealt Rate], TRUE()) I get a value, but I want the first one in terms of the Trade Start Time.  I'm concerned that there may be a millisecond issue here to boot, but anyway, any help most welcome.

      HI wooand

       

      And that value returned would be the minimum of all the DEALT RATES??? Is it?

        No, in this example I would want 1.1726 at the first Trade Time (it's ordered by Trade Time), but for some reason I'm getting some other rate from elsewhere in the data series.
