function [dates opens highs lows closes volumes]=get_symbol_data(symbol,days)
%
% This function returns stock data array by input stock file .csv file and number of days
%
%
% If you have MATLAB, you can use "importdata" function to get the job done easily.
% This script can be run both in MATLAB and in FreeMAT
% If you run this script in MATLAB, please change fgetline to fgetl
%
% 14-feb-2010, notice the zero volume day is in dataset, we have to get rid of these days
