Given the richeness of the API, I'm sure I'm overlooking a simpler way to handle this. Essentially, my algo wants to go short on occassion. But, I want to keep the algo from overbuying. I want to hold cash in reserve to cover the short positions.
So, when I go to open a short position, I need to be able to sum up the value of my short positions and compare that against, presumably, the Portfolio.CashBook["USD"].Amount.
Maybe there's a better way to do this?
What's the best way to sum up the value of all the short positions? I know I can loop through the Portfolio and get all the items where Quantity < 0, but I'm wondering if there's a more elegant solution?

There is no built-in variable in the API that holds this information.
However, if we use some Linq magic, we can calculated it with a one-liner:
var shortHoldingsValue = Portfolio.Values .Where(x => x.IsShort) .Sum(x => x.AbsoluteHoldingsValue);TedVZ
