Johan,
So you are defining the relationship between the
three bars as a mathematical function of the element subscript, and the
condition is identified as true when the numeric value of y equals 3 ?
The first iteration through this is : x = C [
i - k ] >C [ i -k -1 ];
x = C [ 3 - 0 ] > C [ 3 - 0 -1];
<FONT face=Arial
size=2>
= C [ 3 ] > C [ 2 ];
<FONT face=Arial
size=2> y
= 0 + 1 = 1
The second
:
x = C [ 4 - 1] > C [ 4 - 1 - 1]
<FONT face=Arial
size=2> =
C [ 3 ] > C [ 2 ];
<FONT face=Arial
size=2>
y = y + x = 1 + 1 = 2
The
third:
x = C [5 -2] > C [ 5 - 2 - 1] ;
<FONT face=Arial
size=2>
= C [ 3 ] > C [ 2] ;
<FONT face=Arial
size=2>
y = y + x = 2 + 1 = 3
and Cond [ i ] or Cond [ 3 ] == 3, and is
true, except that it looks like only C [ 3 ] > C [ 2 ] has been
tested.
Is this what you have performed here?
I initially described the relationship as : C
[ 3 ] > C [ 2 ] and C [ 2 ] > C [1 ] and C [ 1 ]
> C [ 0 ] , which isn't exactly what I think you have done, but the specific
price relationship wasn't the point of my question. Thank you for
your insight in this.
If I my interpretation is correct, what
would be changed to perform the above?
Might this work?
for ( i=3; i<BarCount ; i++){k = 0
;y = 0 ;
m = 0 ;
while( k <= 2
){x=C[i-k-m]>C[i-k-n-1];y=y+x;k++;
m = m++;
Cond[i]=y==3;}}
First iteration : x = C
[i-k-m]>C[i-k-m-1];
<FONT face=Arial
size=2> =
C [3-0-0] > C [3 -0 -0 -1]
<FONT face=Arial
size=2>
= C [ 3 ] > C [ 2 ]
Second
: x = C [i-k-m] >
C[i-k-n];
<FONT face=Arial
size=2> =
C [4 -1 -1] > C [ 4 - 1 - 1 -1]
<FONT face=Arial
size=2>
= C [ 2 ] > C [ 1 ]
Third
: x = C
[i-k-m] > C[i-k-n];
<FONT face=Arial
size=2> =
C [ 5 -2 -2] > C [ 5 - 2 -2 -1]
<FONT face=Arial
size=2>
= C [ 1 ] > C [ 0 ]
If the initial relationship were : C [ 3 ]
> C [ 2 ] and C [ 2 ] > C [ 1 ] and C [ 1 ] <
C [ 0 ]
How would this be addressed? Wouldn't the
algorithm have to be split into 2 parts?

OK, guess I didn't read your message properly.Does this
help you in any
way:for(i=3;i<BarCount;i++){k=0;y=0;while(k<=2){x=C[i-k]>C[i-k-1];y=y+x;k++;Cond[i]=y==3;}}Plot(C,"",colorBlack,styleCandle);Plot(Cond,"",colorBlue,styleHistogram|styleOwnScale);JohanSend
