Hello,

Could you please assist me with writng a custom indicator that will plot swing lines, with the following rules: 

1. Swing lines connect either Highs or Lows of individual bars - never Open or Close.
2. If the next bar has a higher high and a higher low (or the same low) when compared to the previous bar, then the swing line goes up connecting the high of the next bar.
3. If the next bar has a lower high (or same high) and a lower low when compared to the previous bar, then the swing line goes down connecting the low of the next bar.
4. If the next bar is an inside bar (lower high and higher low), ignore it and don’t plot a line on it at all – wait for the next bar.
5. If the next br is an outside bar (higher high and lower low), plot a swing line on the high of an outside bar if the following bar (one after the outside bar) is lower, OR plot a swing line on the low of an outside bar if the following bar (one after the outside bar) is higher.

a1:=If((H>Ref(H,-1) and (L>Ref(L,-1)),H,prev);
a2:=If((H<Ref(H,-1) and (L<Ref(L,-1)),L,prev);
Your #2 and #3 should look like this, from this code you should be able to work out the rest.

Hi,

Thanks for this.  It's not working. Would you pleasee write the complete formula so I could test it then?

maybe this is what john1 mean: just one more ")"

If((H>Ref(H,-1)) AND (L>Ref(L,-1)),H,PREV);
If((H<Ref(H,-1)) AND (L<Ref(L,-1)),L,PREV);

Thanks.  Now there is no error, but the formula has produced no result/swing line at all.

maybe this is what you most wanted :-)

a1:= If((H>Ref(H,-1)) AND (L>Ref(L,-1)),H,PREV);
a2:= If((H<Ref(H,-1)) AND (L<Ref(L,-1)),L,PREV);

If( a1<>Ref(a1,-1),a1,a2);

Thanks.

I wanted to attach a screen shot of swing lines on a real chart....that would assist in the explanation what it should look like. Do you maybe have an email I could send you that?

  The attachment didn't work Upload it to the internet and give us a link to the jpg.
  Thanks.
 

Where can I upload it?

this code worked, you can see sample with DJ


If((H>Ref(H,-1)) AND (L>Ref(L,-1)),H,PREV);
If((H<Ref(H,-1)) AND (L<Ref(L,-1)),L,PREV);

sample:

If you go to the link above, you'll see what the swing lines should look like (in blue)...it's easier to understand it from a picture.

   Thanks for the chart, much better.
   Play around with-
  
   a1:=Trough(2,C,5);
   a1
  
   It might be closer to what you are looking for.
   Be careful with zigzag, the first zigzag is bogus.   

Thanks. I tried, but it's just not working for me...

Dear Damien:

As per your query following codings would appropriate.

pr:=Input("Reversal amount", 0.001,100000,1);
pk:=PeakBars(1,H ,pr)=0;
tr:=TroughBars(1,L,pr)=0;
oHi:=Zig(H ,pr,%);
oLo:=Zig(L,pr,%);
avg:=(oHi+oLo)/2;
x:=If(H>Ref(H,-1) AND LIf(HRef(L,-1),LOW,
If(HIf((Ref(LOW,-1)>(H>Ref(H,-1) AND L>Ref(L,-1))) ,HIGH ,
If((Ref(HIGH,-1)>(H>Ref(H,-1) AND L>Ref(L,-1))),LOW, If(avg>Ref(avg ,-1),L,H)))) ));
X1:=Zig(x,pr,%);
X1;

But not equals to the indicator ploted on HSI graph that you had sent me via e-mail. You have to rewrite the rules if you want an accurate indicator equals to the indicator ploted on HSI graph .

1- Swing lines connect either Highs or Lows of individual bars - never Open or Close.



2 -If the next bar has a higher high and a higher low (or the same low) when compared to the previous bar, then the swing line goes up connecting the high of the next bar.



3- If the next bar has a lower high (or same high) and a lower low when compared to the previous bar, then the swing line goes down connecting the low of the next bar.



4- If the next bar is an inside bar (lower high and higher low than the previous bar), ignore it and don’t plot a line on it at all – wait for the next bar.



5- If the next br is an outside bar (higher high and lower low), plot a swing line on the high of an outside bar if the following bar (one after the outside bar) has a lower low than the outside bar, OR plot a swing line on the low of an outside bar if the following bar (one after the outside bar) has a higher high than the outside bar.


However i tried to make it equal with the ploted indicator on HSI graph but some thing is missing or over the rules due these reasons i cant able to shape final.



pr:=Input("Reversal amount", 0.001,100000,.96);

pk:=PeakBars(1,H ,pr)=0;

tr:=TroughBars(1,L,pr)=0;

oHi:=Zig(H ,pr,%);

oLo:=Zig(L,pr,%);

avg:=(oHi+oLo)/2;

x:=If(pk,ohi,If(tr,olo,

If(Inside(),PREVIOUS,

If(Outside(),LOW ,If(Outside()>Ref(H,-1),LOW,If(L>Ref(Outside(),-1),HIGH, avg))))));

X1:=Zig(x,pr,%);

X1;
