Good question. This is something we have not tested as of now. Our whole attempt was to implement intraday charting using free data source integrated with Stockalyze.
How do you use Stockalyze? You have intraday data in metastock format and want Stockalyze to show intraday charts? Do you have third-party data provider that keeps updating metastock data in realtime?
I can think of providing support of metastock data for intraday charts. Give me some use cases that will be helpful in implementing it.
