How to calculate number of bars in any swing?

I want to calculate the number of bars between one swing to another swing like zigzag

1- Want to calculate the numbers of bars between
a-H_L
b- L_L
c- H_H
and also want that on high or low of the swing bar indicates the open high low close and volume is this possible
2-i want the same thing with price diffence calculated for the each swing
H-L
L1_L2
H1-H2

TIA

Now try to share my trading charts which help you to improve your trading skill will post over the weekend may be it work for you as It have worked for me as well

Code snippit
===========


double permSwing[9][6]; // first dimension is Period second is value of swing
double permIndex[9][6]; // first dimension is period second is time of swing
int chanTimes[9]={1,5,15,30,60,240,1440,0,0}; // which time frames you would like to populate
int chancount=3; //Number of time frames from above array to populate

void zigZag()
{

for(int j=0;j<chancount;j++)
{
int found=0;
int i=0;
while(found < 4) //finds last four zigzag swings
{
if(iCustom(NULL,chanTimes[j],"ZigZag",9,5,3,0,i)!=0)
{
permSwing[j][found]=iCustom(NULL,chanTimes[j],"ZigZag",9,5,3,0,i);
permIndex[j][found]=iTime(NULL,chanTimes[j],i);
found++;
}
i++;
}

}
}

========
end snippit

You can use the
iBarShift(Symbol(),chanTimes[x],permIndex[x][0]) - iBarShift(Symbol(),chanTimes[x],permIndex[x][1])

where x is the index of the Period and 0 and 1 are the indices of the swings to get the number of bars.

permSwing[x][0] - permSwing[x][1] will give you the difference in value
