On each account you can mark whether it is a challenge, a funded account or your own capital, and enter the numbers from your contract: target, maximum daily loss and maximum total loss.
With that, the dashboard shows at all times how much margin you have left and how far you are from the target, without you calculating it by hand every morning.
If you also turn on limits in Onyx Guardian, it does not just inform you: it stops you. With whatever safety margin you chose, so you never reach the real edge.
