Description
Percent of initial AccountSize to give to this strategy
Input
Any formula specifying a percentage (evaluated once at the start of the test)
Notes
Both S.StartEquity and the initial value of S.Equity for the strategy will be this percentage of the initial account size.
The default StartPercent is 100. This models each strategy having the entire account at its disposal.
Specifying StartPercent less than 100 is useful when modeling strategies running in separate accounts. In this case AccountSize would be the sum of your initial account values and StartPercent would specify the relative percent sizes of each sub-account.
Specifying StartPercent below 100 also changes the strategy's default Allocation from Combined(S.Equity) to the strategy's own S.Equity, so that the strategy compounds on its own sub-account. Percent-based position sizing and capacity constraints such as MaxExposure are then measured against the strategy's own allocation rather than total account value. For example, MaxExposure: 100 means 100% of the strategy's slice, not 100% of the portfolio.
Note that StartPercent: 100 is equivalent to not specifying StartPercent at all; separate-account modeling requires a value below 100.
When using StartPercent: 100 (or not using it since this is the default), multiple strategies should apply their desired allocation fractions via their Quantity formulas.
