Use the next code

let
    Source = Web.BrowserContents("https://pt.investing.com/currencies/gbp-jpy-historical-data"),
    #"Extracted Table From Html" = Html.Table(Source, {{"Column1", "TABLE.freeze-column-w-1.w-full.overflow-x-auto.text-xs.leading-4 > * > TR > :nth-child(1)"}, {"Column2", "TABLE.freeze-column-w-1.w-full.overflow-x-auto.text-xs.leading-4 > * > TR > :nth-child(2)"}, {"Column3", "TABLE.freeze-column-w-1.w-full.overflow-x-auto.text-xs.leading-4 > * > TR > :nth-child(3)"}, {"Column4", "TABLE.freeze-column-w-1.w-full.overflow-x-auto.text-xs.leading-4 > * > TR > :nth-child(4)"}, {"Column5", "TABLE.freeze-column-w-1.w-full.overflow-x-auto.text-xs.leading-4 > * > TR > :nth-child(5)"}, {"Column6", "TABLE.freeze-column-w-1.w-full.overflow-x-auto.text-xs.leading-4 > * > TR > :nth-child(6)"}, {"Column7", "TABLE.freeze-column-w-1.w-full.overflow-x-auto.text-xs.leading-4 > * > TR > :nth-child(7)"}}, [RowSelector="TABLE.freeze-column-w-1.w-full.overflow-x-auto.text-xs.leading-4 > * > TR"]),
    #"Promoted Headers" = Table.PromoteHeaders(#"Extracted Table From Html", [PromoteAllScalars=true]),
    #"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"Data", type date}, {"Último", Int64.Type}, {"Abertura", Int64.Type}, {"Alta", Int64.Type}, {"Baixa", Int64.Type}, {"Vol.", type text}, {"Var. %", Percentage.Type}}),
    #"Filtered Rows" = Table.SelectRows(#"Changed Type", each Date.IsInCurrentDay([Data]))
in
    #"Filtered Rows"

Sorry, I wasn't clear in my question. I need the query to bring the current date. Currently when I update the information the query brings me information from the last 30 days. For example: from 09/01 to the present day. Below is the example of how the base comes (always from the last 30 days). In short: I need to lock the start date and the current date always to today.

Hi @EusebioJr_BR ,

Assuming this is your datasheet:

You can use this DAX to create a calculated table called Calendar:

Calendar = CALENDAR(MINX(ALL('Table'), 'Table'[Date]), TODAY())

Then create relationship:

Now you can use the Calendar table to create a slicer:

Every day when you reopen or refresh the report, the right side of the slicer will automatically change to the current day's date.

Hi @EusebioJr_BR ,

If you are trying to always automatically query data 30 days forward from the current day's date, you can try the following M code:

= Table.SelectRows(#"Changed Type", each [Date] >= Date.AddDays(DateTime.Date(DateTime.LocalNow()), -30) and [Date] <= DateTime.Date(DateTime.LocalNow()))

Here is the whole M code in the Advanced Editor:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("bdQ9igMxEEThuyg2jKpb85c6MTiadDFz/2vsJq4GvQ3Fi/Sh0ufTXs/rff20R1NftC/RY/wdxtruxxQ3x8G4OibjcAzGdBRjOHZGfWOejN3xQDzddrTDbUMzT5LHOkkd4yRxbJO0MU2SxjL5j8y3xQRzLmmXOOYWdokdzS6xodklVjS7xECzSySaXSLQ7BJCs0t0NLsILmEXwUV2EVxkF8Gl5iS41JoElxqT4FJbElxqSoJLLUlwqSGBpWYEFaPAxCQQMQg86nOZS41nLvVE8Mp92Xbfvw==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Moeda = _t, Date = _t, Value = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Moeda", type text}, {"Date", type date}, {"Value", Int64.Type}}),
    FilteredRows = Table.SelectRows(#"Changed Type", each [Date] >= Date.AddDays(DateTime.Date(DateTime.LocalNow()), -30) and [Date] <= DateTime.Date(DateTime.LocalNow()))
in
    FilteredRows
