Agreed.
I appreciate number formatting and date/time formatting varies (I'm originally from the States so living in a DD/MM/YY country still kinda confuses me at times) but it is already present - not when you input your number to the trade, but at least when you see the final result there are separators for 1,000 so I would think the same rules could apply consistently. I take for granted that most people understand the 1 thousand separator.
