Is there a way to access with Apex the list of the fields that are tracked in the account history?
I haven´t found a describe call for this purpose.
Answer
Since Winter ’16 this can be achieved using the IsFieldHistoryTracked field on FieldDefinition.
To get all tracked fields on Account you can use:
SELECT QualifiedApiName FROM FieldDefinition WHERE EntityDefinition.QualifiedApiName = 'Account' AND IsFieldHistoryTracked = true
