@lumilog
Hey thanks for helping out earlier. I need some help again.
I have modified your code to get various statistical values from yahoo finance. But, the problem is when I try to write that value in excel(for further equity report update).

for eg: to get avg_vol
function avg_vol = get_avg_vol(stock_symbol)

stock_symbol = upper(stock_symbol);
% Open connection to Yahoo! Finance statistics page
fprintf(1,’Retrieving Average Volume(3 month) for %s…’, stock_symbol);
url_name = strcat(‘http://finance.yahoo.com/q/ks?s=', stock_symbol);
url = java.net.URL(url_name); % Construct a URL object
is = openStream(url); % Open a connection to the URL
isr = java.io.InputStreamReader(is);
br = java.io.BufferedReader(isr);

% Cycle through the source code until we find Average Volume…
while 1
line_buff = char(readLine(br));
ptr = strfind(line_buff, ‘Average Volume’);

% …And break when we find it
if length(ptr) > 0,break; end

% Handle the case where either data not available or no Average Volume
no_data = strfind(line_buff, ‘There is no’);
if length(no_data) > 0,
fprintf(1,’Yahoo! Finance does not currently have Average Volume for %s.\n’,stock_symbol);
avg_vol = NaN;
return;
end
end

% Just to make it easier, strip off all the preceeding stuff we don’t want
line_buff = line_buff(ptr:end);

% Extract the Average Volume(3 month)
ptr_gt = strfind(line_buff,’>’);
ptr_lt = strfind(line_buff,’<’);
avg_vol = (line_buff(ptr_gt(6)+1:ptr_lt(7)-1));

if length(avg_vol) == 0
fprintf(1,’N/A\n’);
else
fprintf(1,’ = %s\n’, avg_vol);
end

——————————–
by doing this, avg_vol is stored as a character with commas. How can I get the vol amount directly so that I can write it directly to excel in matlab.
This holds true even for market cap which is represented in ‘M’

thanks for helping out earlier.

To get Forward P/E I had to make 3 changes to the file (if you’re interested search the code for comments “Change #1″, “Change #2″, and “Change #3″).

Here’s a link to it.
get_fwd_pe.m

Hi, I am trying to use the code to extract “forward pe’ data. But the thing is, on the source code the forward pe value is located on the next line. please help

Hey man, I have been reading all the posts in your blog.please help me, i have few queries.

So can you tell me how to make use of these codes with matlab?
should i enter the same code in matlab?
where and how should i use this code?
your response will be greatly valuable to me, and enhance my learning.

Thanking you in advance……………
