I think u can get these values & no of bars from latest close (Pivot highs & lows ) from text marked red & green. But how, I dont know.
Can u help me please.
see attached chart.

Hi Ajax,
try this.
for including close, try this:
try this.
Code:
GraphXSpace = 20;
dist = 1.1*ATR(20);
for(m=0;m<=BarCount-1;m++){
if(aHPivs[m] == 1)PlotText("" + (BarCount - m - 1), m, H[m]+dist[m],colorBlack);
if(aLPivs[m] == 1)PlotText("" + (BarCount - m - 1), m, L[m]-dist[m], colorBlack);
}
Code:
GraphXSpace = 20;
dist = 1.1*ATR(20);
for(m=0;m<=BarCount-1;m++){
if(aHPivs[m] == 1)PlotText("" + (BarCount - m - 1) + "C" + C[m], m, H[m]+dist[m],colorBlack);
if(aLPivs[m] == 1)PlotText("" + (BarCount - m - 1) + "C" + C[m], m, L[m]-dist[m], colorBlack);

Hi Aushotosh
Thanx a ton for the formula. It really shows nicely on the charts the desired values...
Now a step further...
Need to build a Automatic analysis query
Need values of last 2 Pivot tops & last 2 Pivot Lows
T1 = Last Pivot high
T2 = Previous Pivot high (before T1)
B1 = Last Pivot low
B2 = Previous Pivot low (before B1)
Buy = Close > T1 and T1 > T2 and B1 > B2
Sell = Close < B1
I think from code u gave us, its possible to extract these values
Please help
Regards
PS: I will post this as AFL. Also see attached chart

Hi Ajax,
Remove the previous code and add this instead:

Excellent Coding.
Hello Ajax,
Besides using HHV / LLV (as you have done) for the plotting of the pivot points we can also use zigzag function. If you have tried coding patterns like 3BR, you can use similar code for marking PPs, will post the code after mrkts.
Overall a very nice effort, keep plugging.

Sanjay

ZigZArray = Zig(C, change);

Hi Ashutosh
Tried to run the automatic analysis with Pivot code + above code.
Its giving following error:
Line 111 column 20..Error 10 Subscript out of range. You must not access array elements outside 0..(Barcount-1) range.
It seems program does not run beyond Line 111 because of this error.
I am totally ignorant about how to program. Ashutosh u have to bail us out.
Waiting for u to fix this problem
