Swing Line indicator by Ron Black

A precise picture of the short-term price swings is basic to understanding the market direction. The Clear method is an effective way to identify and visualize short-term price swings. The method benefits the individual trader because it is simple, objective, requires no calculation, and has no delay.

This indicator is the implementation of the swing line indicator presented in Ron Black’s article in this issue (“Getting Clear With Short-Term Swings”).

    Nicolas, ho realizzato un screener dall’indicatore swingline ron-black, che allego. Vorrei però intercettare il cambiamento di swing da ribassista a rialzista, al cambiamento di posizione. Invece lo screener mi restituisce tutti i titoli che al momento sono in fase rialzista. Ho provato a mettere un supertrend per limitare i risultati ma non sono ancora soddisfatto. E’ possibile, a tuo parere, avere una soluzione che trovi i titoli che hanno cambiato swing nella barra precedente alla ricerca dell screener?

    Hi Nicolas, could this indicator be used on forex?

  7. Francesco • 09/20/2017 #

    Hi Nicolas,

    the Swing Line Indicator translate by You seems to be good.
    I thought that it can be used into a screener, simply replacing the “swingline” output variable with the “upsw” as output variable.
    Then, it can be built a new screener that gives the ticker which shows a change from 0 to 1 or from 1 to 0, simply comparing current candle with the previous one.

    I added code for Your review, if You like.

    Ciao

  8. MattD • 09/20/2017 #

    Hi Nicolas,
    Just to confirm, h=previous high and H =todays high, l=previous low and L=Todays low?? Just wanted to place the formula in excel and trying to get my head around writing it.
    Thanks
    Matt

    • Nicolas • 09/20/2017 #

      hH = highest high lH = lowest high etc..

    • MattD • 09/20/2017 #

      Hi Nicolas, Can you assist me with writing this in excel? I’m missing something, because l’m not getting the specified numbers in that chart to match. Mainly around selecting the high & low.
      Thanks
      Matt

    • Nicolas • 09/20/2017 #

      Hi Nicolas, (me again)

      Can you please clarify the following.

      maOpen=(maOpen[1]*(MAperiod-1)+Open)/MAPeriod
      maClose=(maClose[1]*(MAperiod-1)+Close)/MAPeriod
      maLow=(maLow[1]*(MAperiod-1)+Low)/MAPeriod
      maHigh=(maHigh[1]*(MAperiod-1)+High)/MAPeriod

      I’m trying to understand where/what these figures are derived from.
      Starting from O,H,L,C figures. maOpen(1) (what does the (1) signify, and is Maperiod -1 essentially the setting “maperiod less1?

      trying to match the numbers on PRT.
      Can you please help with this one?
      Thanks
      Matt

    It seems to be very interesting! Can somebody better explain how they are created? Given my limited knowledge of programming language I failed to give me a precise idea of how it functions.

    Bonjour
    Merci pour ce travail, par contre, un petit bug dans le code de Supertiti à la ligne 23 mais sûrement corrigé de vous-même . if high< lH then (mine de rien on essaie de suivre…) le ''<'' avait disparu.

  11. Juan Kumi • 09/20/2017 #

    Is it possible to create a binary indicator for this indicator? What?

    • Nicolas • 09/20/2017 #

      Should be possible but what do you think of precisely?

  12. Juan Kumi • 09/20/2017 #

    I would like the indicator to +1 when swing line is light blue, and opposite -1 when the swing line is purple.

    • Nicolas • 09/20/2017 #

      Just add the r and g variables to the return instruction and you’ll get the information of the current color (r or g would be equal to 255 if the actual trend is bearish or bullish, otherwise it would be equal to 0):
      return swingline coloured(r,g,b) style(line,2) as “Swing Line”, r, g

  13. Juan Kumi • 09/20/2017 #

    Thanks but I did not succeed. Can someone help me?

    Bonjour,
    Je n’arrive pas à faire fonctionner cet indicateur?
    Quel est le bon code dans sa totalité?
    Merci

    • Nicolas • 09/20/2017 #

      Il suffit de le télécharger, de l’importer et de l’appliquer sur le graphique du prix.

    Nicolas…loving this indicator that you have created!!! Thanks for sharing with everyone! I’m not a profectional indicator’s builder…can you please, when you have time, insert a link here of this indicator (your original version with no MM) but with the signal for long/short enter indicated with the bars below the graphic…green to buy and red to sell…like the one you created for the divergences…I know that someone already asked for it and you have answered him, but following that instructions I’m not able to modify it correctly…if it is not a disturb!
    Thanks so much!
    And another request…don’t hate me:)….how can I indicated, inside a TS, to go long only if this indicator is setting in long way(coloured blu) or short if it indicates to go short(coloured pink)?
    Thanks again

    • Nicolas • 09/20/2017 #

      Sorry but I don’t understand what you are talking about the “original version with no MM” ?

  16. avatar
    fabioerliam • 09/20/2017 #

    I’m reffering to the first code you posted here…after that, someone has add a ponderate average (sorry…in italian called media mobile MM) but I don’t need it… I would like that you can modify for me the original code indicator you posted:)…
    Thanks

    Hi Nicholas, congratulations always for your work and sharing.
    I wanted to ask if with the ron black indicator you can program a trading system.
    Thank you

    • Nicolas • 09/20/2017 #

      Please post your code request in a specific topic in the ProOrder forum, thank you.

  18. Ayoub86 • 09/20/2017 #

    Hi,
    I get this error:

    “Errore di sintassi: Linea 48, carattere 27 Uno dei seguenti caratteri sarebbe più appropriato di “r”: – a color value (0 – 255)”

    how can I solve it?

    thank you

    • Nicolas • 09/20/2017 #

      Your PRT version is inferior to 10.3? So the code in its default state is not compatible. A solution is to delete all references to variables r,g and b in the code.

  19. Mbulelo • 09/20/2017 #

    Hi Nicolas

    Hope all is well your side, do you have a specific strategy for the MFT Swing Line indicator Alert?

    • Nicolas • 09/20/2017 #

      No I don’t, try to make it on your own, or ask in forums (follow the posting rules please).
