And one more question about dataproviders....
There is a scale parameter to get history. Is this scale parameter customizeble? I mean to add custom scale now supported from dataprovider... Is it derived from enum of possiple scales that dataprovider provides?

If you're asking about the API, the SupportsScale() function queries Data Providers for, wait for it...., the supported scales.
