My trading strategy was developed because I'm DD averse. The way I see it there are only a few ways to avoid DD, main two being: Less risk; Better Entry. Personally I focus on great entries and tighter stops.
If you find your plan having multiple days of high DD 30-40%+, your trading strategy is likely flawed. At any moment this DD could become too much for your account to bear (Imagine holding GBPAUD buys this week). As well, you're also missing out on any number of better opportunities because this large portion of your account is locked into one trade.
