Below is a list of mathematical functions available for your StockFetcher filters:

  • abs(IND): return the absolute value of the input measure.

    Fetcher[abs(close minus open) is above 2.0]



  • log(IND): take the natural log of the input measure.

    Fetcher[log(RSI(14)) reached a new 6 week high]



  • log10(IND): take the loge, base-10 of the input measure.

    Fetcher[log10(RSI(14)) reached a new 6 week high]



  • max(IND1,IND2): return the maximum of two values.

    Fetcher[
    show stocks where max(MACD Fast Line, MACD Slow Line) crossed above 0
    and draw MACD
    ]



  • min(IND1,IND2): return the minimum of two values.

    Fetcher[
    show stocks where min(RSI(14),Smoothed RSI(14)) is above 60
    and draw Smoothed RSI(14)
    ]



  • sign(IND): return just the sign (1,-1) of the input measure.

    Fetcher[sign(MACD Fast Line) equals 1]



  • sum(IND,LENGTH): return the sum of a measure, over the specified length.

    Fetcher[
    set{diff, close - close 1 day ago}
    set{product, diff * volume},
    show stocks where sum(product,10) crossed above 0
    ]



    Please let us know if there are any that you would like to use, but do not see above!

    Thank you,

    How about having the max and min functions to be applicable over a period of time like the sum function? That is:

    min(ind, LENGTH)
    max(ind, LENGTH)

    I can use Donchian channel concept to achieve this for price, but not for volume and other indicators....

    Also I noticed that when I use add column with the sum function it works, but the min and max functions are not recognized by the add column... such that

    add column min(PVO(1,60) 1 day ago,PVO(1,60)) does not work, whereas

    add column sum(PVO(1,60),3) does work.

    I also can't use the user defined variables with the add column function...
    Thanks.

    parttimer,

    Can't you just use "ind LENGTH day high" and "ind LENGTH day low"? (e.g., price 15 day high = max(price,15); volume 30 day low = min(volume,30))

    HTH,

    C

    Please Mark === for correct filters and xxx for incorrect filters

    Low > Low 5 day low 1 day ago
    Low > Close 5 day low 1 days ago
    Low > Low 5 day Close 1 day ago
    Low > High 5 day Close 1 day ago
    Low > Close 5 day High 1 days ago
    Low > Open 5 day Close 1 day ago
    Close > Low 5 day low 1 day ago
    High > Close 5 day low 1 days ago
    Open > Low 5 day Close 1 day ago

    Any rules pertaining to thie kind of filter?
