Backoffice System (Advanced)

home/Knowledge Base/Technical Support/FAQ's/Back End (Registered)/Backoffice System (Advanced)/We want to change the tradable amount of lots from (0.1, 0.2, 0.3, 0.4, 0.5) to (0.2, 0.4, 0.6, 0.8), which means to let clients trade on (0.2, 0.4, 0.6, 0.8 and so on). How can we do that?
