Gold - 24k (5 Gram) and (2.5 Gram) coins support

Please add Gold Commodity Assset form of 24k Gold (5 Gram) and 24k Gold (2.5 Gram) as well.

Also, not sure why the app is not allowing setting the older trade date for 25k Gold (1 Gram and 10 Grams). This is the error message: “Trade date must be on or after 2025-10-22”
