Daily Test Statistics
Peak fraction of allocation used in open positions by this strategy on this test date
S.Usage is calculated as the sum of FillFraction for each position that was open at any time this day.
S.Usage, like FillFraction, is always positive, regardless of side.
The purpose of this stat is to show the maximum intraday capital usage required to trade the strategy (or Combined strategies).
To constrain a strategy or set of strategies to not exceed a S.Usage cap:
•in the default top-down mode use MaxExposure
•in Legacy Mode use an EntrySkip formula that references S.Usage
