There is one choice in metatrader4 to save info about chart (Filegt;Save).
An individual can save info about particular chart in ASCII text(*.csv) from ASCII text(*.crn) or as
HTML document(*.htm)
Now I want to store graphs data for potential testing,however I don`t know what document type to use.
Can I use ASCII or HTML?

And once I save those files,how can I acces them?I mean how can I turn them into graphs
utilizing metatrader?Do I need some other software?

Thanks for Assistance
