We have developed a financial algorithm that we tested using historical stock price data(read from a text file). Next we want to run the algorithm as a real life simulation.
My idea is to write an additional Perl script that gets stock price from yahoo finance and updates a file X. Then it calls the matlab program, which reads the file X and outputs the data in a file Y(csv,text ... format). I can then use excel or other application to read and plot the output file.
Question: What do you think about my strategy? Is this the best strategy? Can I call the Matlab program directly from Perl? Can the whole program be written in Matlab itself without reverting to Perl? Please advise.

It would be great if Matlab adds an example to show how to stream data from the Datafeed toolbox in real time to a live intraday price chart.
