I saw there is a finance tag in math.SE, and people are allowed to ask directly finance questions in math.SE. Curious why?
Although finance questions could need math calculations, a lot of other backgrounds/conversions/terms might get involved. Plus the way finance question is asked usually is not the same as mathematics, and thus you need to switch context a bit in understanding the questions and terms.
Why don't we have a separate board for finance? And if someone needs to ask math involved in finance, he/she could abstract the math out and ask in math.SE without involving any finance context.
