Caps the added exposure from entry orders placed per day by a strategy
Input
Any formula that returns a percentage
Notes
At each step of the setup selection process, MaxNewExp is considered along with each of the other top-down constraints.
If, for example, MaxNewExp is 20 and there have already been two other setups with 10% position size selected for order placement, this setup will be rejected even if adding it would not violate any other constraint.
