    Hello,

    I’d like to extract data before and after 1000 from extrema.

    I created following formula but it doesn’t work.

    Dim myP = GlobalExtrema(‘Dataset1’,EVENT_POSITIVE,EVENT_INDEX)
    Dim S, F
    S = myP – 1000
    F = myP + 1000
    ‘Dataset1′[S, F]

    Please tell me what’s wrong with it 😥

    The GlobalExtrema-function returns a data series with the indices. Therefore you have to change your FPScript formula as follows:

    Dim myP = GlobalExtrema(‘Dataset1’, EVENT_POSITIVE, EVENT_INDEX)[b][0][/b]
