    It is better to contact the Eikon Excel support team to verify how to do it in Eikon Excel with the =TR function.

    Then, we can convert the formula used in Eikon Excel to Python code.

    For example, "Let's say the S&P 500, which their end of day prices are above or below their 50 (100 or 200)". We can use the following code to get 50-Day SMA.

    df, err = ek.get_data("0#.SPX",["TR.Price50DayAverage","TR.PriceClose"])
    df

    Then, we can calculate the percentage of stocks that have end-of-day prices above 50-day SMA.

    (len(df[df["Price Close"] > df["50-day SMA"]])/len(df))*100

    The output is 30.89%.

    In conclusion, please directly the Eikon Excel support team via MyRefinitv (https://my.refinitiv.com/content/mytr/en/helpandsupport.html) to verify how to do it in Eikon Excel. Then, we can convert the Excel formula to the Python code that uses Eikon Data API to retrieve the data.
