    excellent robert, here are two lines to enhance this code with color histograms
    just after line 11

    if Shi “bigger than” 0 then
    r = 220
    g = 20
    else
    r = 20
    g = 220
    endif

    return Shi coloured(r,g,0) style(histogram) as “Shi”, 0 coloured by 0 as “0”

    Thank you swapping, much appreciated. I usually do not hard code graphic styles and colours within my code, as this makes it impossible for users to change settings from the indicator’s properties, though, unless they change the code.

    Dear swapping I tried to insert your instructions to color the histograms but I have an error on “bigger than”. In fact I have already modified the SHI with the color zones that it offers prorealtime to improve the visualization. Thank you

    Bigger than needs to be replacec by the symbol >

    Roberto, another request concerning the code: is it possible to change the ema 14 with another period (10 or 20 for example)?. Thank you

  6. robertogozzi • 03/15/2019 #

    If you import the .ITF file you may use the indicator properties to set periods.
    If you Copied & Pasted it then you’ll have to define that variable yourself.

  7. luxrun • 03/15/2019 #

    Ok, thank you

  8. robertogozzi • 03/15/2019 #

    I just discovered that ProOrder (for automated strategies) does not evaluate the expression in line 10 correctly (as Probuilder does), so if you want to embed the code in your strategy you need to replace that line with:

  9. robertogozzi • 03/15/2019 #

    //Ti = ((close > Cy) * Tt) OR (((close Cy) THEN
    Ti = Tt
    ELSE
    Ti = -Tt
    ENDIF

    Roberto, I tried again to use both the SHI indicator and the WPO oscillator but they don’t work on version 11 of Prorealtime. Graphically you see a solid line and nothing changes if the periods of Ema and Sma vary. Sorry, but having read the pdf you indicated I find this kind of cyclic indicators interesting, thanks

  11. robertogozzi • 294 days ago #

    WPO should work as posted at https://www.prorealcode.com/prorealtime-indicators/wpo-wave-period-oscillator/.
    Copy lines 16-20 to SHI replacing line 10.
    The five lines are the same in both indicators.
    PRT said they had worked out math with boolean values, but it doesn’t seem so.

    Now is ok! Thanks a lot
