"I'm an avid user of the chart library. The period pull down menu lists 50 years (max) as an option yet the charts do not display 50 years of data.

"Please look into this matter for me. Thanks"

Eoin Treacy's view Thank you for this question email which raises an issue others may also have an interest in. We receive our data feed from Bloomberg. For instruments such as gold or IBM which have price history going back many decades we can draw up to 50-year charts. However with other instruments, such as platinum, the data is not as lengthy so we cannot draw 50-year charts.
