I have following Classic Algorithm that hourly rebalances the portfolio with setHoldings. I would like to convert this into a Framework algorithm so that I can benefit from the more advanced execution models (such as stdev, wvap) that are already available there for plugging into other portfolio balancing samples (uniform, mean-variance, black-litterman) within the framework. I would be more than glad if someone from the community can help me in achieving that.
