Extract data around extrema

[Anonym]

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)[0]
