Algorithm Framework Leverage Example

Does anyone here have any example of how to use leverage in an algorithm framework?  I tried calling SetLeverage, the overload of AddEquity that has a leverage input parameter, UniverseSettings.Leverage and none of them seem to add leverage upon execution of the order.  I am using the plain vanilla EqualWeightingPortfolioConstructionModel and ImmediateExecutionModel.  The only way I know how to add leverage is via SetHoldings but that is not using the algorithm framework.  Please advise.

Thanks!

I figured it out so I'm going to answer my own question.  You just have to override the DetermineTargetPercent function on the PortfolioConstructionModel and change the 1m to your new leverage:

protected override Dictionary<Insight, double> DetermineTargetPercent(List<Insight> activeInsights)
{
var result = new Dictionary<Insight, double>();

// give equal weighting to each security
var count = activeInsights.Count(x => x.Direction != InsightDirection.Flat && RespectPortfolioBias(x));
var percent = count == 0 ? 0 : 1m / count;
foreach (var insight in activeInsights)
{
result[insight] =
(double)((int)(RespectPortfolioBias(insight) ? insight.Direction : InsightDirection.Flat)
* percent);
}
return result;
}

Thank you for sharing it back Jon :) You are correct that it is the PCM's job to determine the positions weighing up the leverage of the securities.

Hi Jon,

The EqualWeightingPortfolioConstructionModel does not store a reference to the algorithm object and the reference is not provided to the DetermineTargetPercent method. Therefore, we have no way of accessing the UniverseSettings property.

However, we can access the algorithm object and utilize its UniverseSettings by creating a custom portfolio construction model and overriding the CreateTargets method. Refer to my comment on this thread for an example.

Best,
Derek Melchin
