Price Range Box Size
0.00 to 5.00 .25
5.01 to 20.00 .50
20.01 to 100.00 1.00
Over 100.00 2.00
But if anyone sees a reason to change this let me know.

Richard,
>From http://stockcharts.com/education/How/AnalysisTools/pnfCharts.html:
Traditional box scaling preloads box sizes historically used for that
particular price range. The reversal amount starts at 2 (this should be 3),
but can be adjusted dynamically. Here are the traditional box sizes used in
our charts:
Price Range Box Size
Under $0.25 .0625
.26 to 1.00 .125
1.01 to 5.00 .25
5.01 to 20.00 .50
20.01 to 100.00 1.00
100.01 to 200.00 2.00
200.01 to 500.00 4.00
500.01 to 1,000.00 5.00
1,000.01 to 25,000.00 50.00
25,000.01 and up 500.00
The traditional scaling in PnF.dll only uses .25 (less than $5) up to 2
(greater than $100) because I have been a student of Dorsey Wright long
before StockCharts came along, but the DLL can change when and if needed.
Plus you have the ability to use your own boxsize in the DLL.

Looks great, Peter. Can you elaborate on what is meant by the
traditional scaling? "x = Boxsize (use '0' for traditional scaling)or
provide a reference. I was checking out Kaufman and I couldn't find a
recommended box size.
Thanks,
Richard

Hello Mirat,
Good stuff!! I made some modifications to your code to call my
Point & Figure DLL and plot the data using your jscript code. I tested it
on one stock (PYPL - short history) and it looks correct (except for the
beginning bars:
I have attached the AFL to this email (and posted below for Yahoo
viewers).
Thanks again,

Hello Richard and Dimitris,
Sorry to have caused so much confusion.
Since most stocks since 2000 have been trending down, you may get a
only a few bars because the P&F Chart ignores small up moves and
only
extends down bars when the price moves more than the box size.
Since
2000, you may very well have only a few bars. Try loading more data
for at least one stock.
I used AmiQuote and Yahoo for the data. I have data from January
1994. The AmiBroker version on which I created this file is 4.0.0
Apr 26 2002.
I do not know if the AmiBroker version is causing the difference. I
saw that it worked for Richard on MSFT (although I am not sure what
the whole MSFT v. MSFT issue was - it seems to have resolved
itself). Perhaps Richard also has more data loaded.
As you can see from the script, it is very simple. If problems
continue, I would be happy to go through it in detail to see if
there
is a coding error.
I'm afraid I have no other explanation other than more data. Let's
try that first.
Mirat
PS I would post .gifs of my charts but I do not know how to attach
a
file to my reply. Although that would not help resolve the issue.
:-)
