Hi,
Just published the 8th video of my algorithmic trading course using Python and the QC platform. Below you can find the backtest and code from that video. Simply click the “Clone Algorithm” button to copy the code to your own projects.
If you're new to the series, you can get an overview of all the video lessons here.
Let me know if you have any questions or comments.
Cheers,

Hi Louis Thanks for the video! I have one question: when we execute self.SetHoldings(self.portfolioTargets), what happens to the securities which are already in portfolio and in portfolioTargets too? I suppose if the ratio is same then nothing will happen, but if it's changed then it will be bought/sold according to the ratio specified? Am I interpreting it right? Thanks.

Hi Log Up
There would be no effect on other existing positions. The SetHoldings method is actually placing MarketOrder in quantity representing a proportion of the portfolio value for an asset.
If you want to rebalance the portfolio, you could consider
1. Liquidate all positions and use SetHoldings with a list of PortfolioTarget
2. using the Framework and InsightWeightingPortfolioConstructionModel. Active insight weights sum up larger than 1 will rebalance when new insight arrives. This could avoid excessive orders when singular order is desired instead of a whole portfolio change.

HI Louis Szeto , thanks for the reply. Let's say I have SetHoldings with TSLA as 0.1(10%) previously, and in next iteration of OnData I set it to 0.2(20%) of my portfolio, then what will happen in this case?

Hi Log Up
For the same asset, it would hold the new set ratio (i.e. 20%). The other assets would not change their existing positions although (they will not automatically rebalance/adjust).

Hi Louis,
thank you for the videos.
I am just a beginner and have watched your videos.
Please I have some questions regarding AddUniverse with CoarseSelectionFunction and FineSelectionFunction
In your videos, you have selected
Coarse: Securities with FundamentalData that have DollarVolume > a certain amount.
But I also want the Filter to include: Industry, segment, etc.
Please how can I add those to my CoarseSelectionFunction?
I am inspired by video #8 and the More Advanced Fundamental Investing bot video in your education series.
Thank you.
Samuel
