I'm looking for an programmer who can help me program and backrest some strategies.

1. What OS (Windows, Linux)?
2. What platform (C++, C#, Excel, none of the above)?

The only thing I don't know how to do is get data from websites to use for tests.

1. Does it mean that you already have your application written and need just to get data from a website for back testing?
2. How is this data stored on the website (database, text files, proprietary format files etc?) Could you be more specific?


Do you have in mind any kind of compensation?

 

I can test it for you on my data ?

 

Feel free contact me for a free estimation.

Alex.

 

There are a few easy ways to get the data from yahoo finance directly.
The following is the example for matlab code as your reference:
-----------
3. The matlab code:

%download stock data

nyseExcelName = 'NYSE.csv';

nasdaqExcelName = 'Nasdqa.csv';

[num, nyseText, raw]=xlsread(nyseExcelName);

[num, nasdaqText, raw]=xlsread(nyseExcelName);

nyseCompnameList = nyseText(2:end,1);

nasdaqCompnameList = nasdaqText(2:end,1);

url = '';



for i = 1:length(nyseCompnameList)





name = char(nyseCompnameList(i));

url = ['http://ichart.finance.yahoo.com/table.csv?s' name '&a=00&b=01&c=1900&d=03&e=7&f=2011&g=d&ignore=.csv']

s = regexprep(name,'/','_');

s = regexprep(s,'\','-');

fname = ['..\hdata\NYSE-' name '.csv']

downloadCVSByURL(url,fname);



end

for i = 1:length(nasdaqCompnameList)



name = char(nasdaqCompnameList(i));

url = ['http://ichart.finance.yahoo.com/table.csv?s' name '&a=00&b=01&c=1900&d=03&e=7&f=2011&g=d&ignore=.csv']

s = regexprep(name,'/','_');

s = regexprep(s,'\','-');

fname = ['..\hdata\NASDAQ-' name '.csv']

downloadCVSByURL(url,fname);

end



-----downloadCVSByURL.m

function msg = downloadCVSByURL(urlName, fileName)



try

historicalPriceFile =urlread(urlName);

if(isempty(historicalPriceFile)==true)

return;

end;

fid = fopen(fileName,'w');

fwrite(fid,historicalPriceFile);

fclose(fid);

catch err

msg = sprintf('%s', err.message)

end

The smiliar to C++ or Java code but with different API invoking.
