Oui, je suis français. Je vis et travaille à Paris. Mais je me fiche de football si tu vois ce que je veux dire...
Merci pour la qualité de tes réponses. Tu sembles maîtriser Metastock en profondeur. Je continuerai, sauf avis contraire de ta part, à te poser mes questions en anglais pour que les anglophones puissent profiter de tes astuces...
Si ce n'est pas trop indiscret, travailes-tu uniquement sur l'évolution de Metastock ou développes-tu également des systèmes de trading ?

A bientôt !

In fact, I'm a newbie on trading systems. As you seem much more advances than I, I wanted to know if you tried to code something based on some basic principle :
the trend is bullish if higher highs and higher lows.
the trend is bearish if lower highs and lower lows
But I wish I could avoid to predefine the time span.

So I was considering something on peaks and throughs based on three "active" barcharts. The problem is then to be able to define "active" barcharts backwards. It is much more straightforward by just considering the first bar of the chart as an active bar and then to see is the new one adds some information (i.e. lower low or higher high). If so, we have the two active bars that are necessary to find some peak and through progression :
- the third bar will be considered as active if it goes above or below the Max (Active Bar 1, Active Bar 2) or Min Active Bar 1, Active Bar 2)
- peak : if Close Active Bar 3 < Open Active Bar 1
- through : if Close Active Bar 3 > Open Active Bar 1
Doing the work backwards is more difficult, because of inside bars.
I'm not sure that my explanation and my english are clear enough. So I quickly drew the "system" on a chart. There is, a least, one error (the second sell signal could have been avoided, since the close is above the open of on October 1st), but it should clarify what I would like to do.

Thanks for your comments !

No problem Patrick !
I appreciate your help. In fact, I don't want to use such "swing points" alone. I would like to couple such basic trend following with indicators.

Hello Patrick,

I cannot open your ".bmp". Can you please try again or send me the graph on my private email
Thanks a lot !

Hi Patrick,

I can see your chart now. Unfortunately, it does not fit to my vision of active barcharts. It begins well but after the very wide bar, the trouble begins. I tried to label on several "decisive" bars why I don't agree.
I see that your bands do not reflect the Min and Max of the two previous active barcharts. But you seem to be quite close...
Shall I try to explain again the kind of swing points I wish to modelize or was it clear the first time ?

Good evening !

I did not forget about this ... I'm just having a hard time doing it :oops:

I don't give up easily though.
I will let you know if I find the solution.

I don't know if this is correct, but I figured I would post this :

CD:=Inside();
CD1:=If(CD,0,
If(CD=0 AND
(H>Max(ValueWhen(2,CD=0,H),ValueWhen(3,CD=0,H))
OR
L<Min(ValueWhen(2,CD=0,L),ValueWhen(3,CD=0,L))),1,0));
CD2:=If(CD1=0,0,
If(CD1 AND
(H>Max(ValueWhen(2,CD1,H),ValueWhen(3,CD1,H))
OR
L<Min(ValueWhen(2,CD1,L),ValueWhen(3,CD1,L))),1,0));
CD2
