Hi,
I am an expert web developer. I can modify your html, adding some Php code and the script with a loop, should display as many charts as are allowed by bigcharts, i.e., if you put 100 tickers in text file, the script would display 100 charts unless bigcharts restricted number of fetches.
Can start this right away and complete within few hours. Look forward to doing this job.
Thanks,
Sri.
