Trade Line

A trade line is a record of activity for any type of credit extended to a
borrower and retorted to a credit reporting agency. A trade line is
established on a borrower credit report when a borrower is approved for
credit. The trade line records all the activity associated with an account.
Comprehensively, trade lines are used by credit reporting agencies to
calculate a borrower credit score. Different credit reporting agencies give
differing weights to the activities of trade lines when establishing a credit
score for borrowers.
Trend lines are easily recognizable lines that traders draw on charts to
connect a series of prices together or show some datas best fit. The
resulting line is then used to give the trader a good idea of the direction in
which an investments value might move.
