The math, in the open
- Max loss = risk input applied to account size
- USD 100
- Daily room at start = account size × daily DD %
- USD 500
- Daily room now = daily room at start − already used today
- USD 500
- Daily room after trade = daily room now − this trade's loss
- USD 400
- Share of remaining daily room used by this trade
- 20%
- Max-DD room = account size × max DD %
- USD 1,000
- Max-DD room after trade = max-DD room − this trade's loss
- USD 900
