Hi, there is a bug in the notification badge (beside setting). The badge alway there even if we have click to see. (so always >99) when dont know when there is new notification
If you select the all and click "x", you will remove previous history so you can track the trades you will make.
Thanks for the tips. Hope to still keep the history but can mark as read to only show new notification as badge number 1,2,3...
