Hi All,

I have been working on a simple long only Equities strategy. As part of the strategy I have been monitoring TotalTotalMarginUsed. 

I have nominated starting capital = self.SetCash(100000), 

Despite using a weight = 1, the Log is showing TotalTotalMarginUsed of $50,000 or 50% of self.Portfolio.TotalPortfolioValue. I believe it should be $0 and 0% for weight <=1?

When using weight = 2, the Log shows TotalTotalMarginUsed of $100,000 or 100%, as expected.

Can anyone explain why the backtester is using Margin when it still has FreeCash available?
