Share New Research 
We updated the order fill models for live trading to allow partial fills. This is managed by a "OrderEvent" class. A single order can have multiple order events (e.g. 1000 shares filled in 2x500 lots over time at different prices). The backtest attached has a $500 per trade fee which gives us the sharp drops in the backtest curve!

Thanks @Eric -- we've since dramatically improved all the modelling. I've updated the QC University algorithm to use the correct models now. The algorithm attached above is fairly old (Nov-2014); but if you go to the algorithm terminal, and click on the university cap on the left side you can find the same Transaction model example project. I've attached a copy of it here for your reference.
