Long/Short trading strategy w/ ML forecasted stock returns

Using Data Machine Learning Market Neutral

Current status: Algo has been taken down while we fix an issue with the code!

Hey folks,

We recently released Logitbot's 100/500 ML stock return predictions datafeed into Pipeline and wanted to show you how to use it in an algorithm. This is a version of Logitbot's algorithm that's been ported over to be Q2 and utilizes the pipeline.

This algorithm hosts a few improvements over the original:

  • Limiting the number of stocks held to 200 to control leverage (which is settable)
  • Closing the positions that are held for longer than 5 days whereas the original strategy simply held securities
  • Picking the highest and lowest predicted returns (rather than just ones that pass the threshold)
  • Buying long term bonds when enough stocks don’t fit the criteria
  • Using Logitbot's data through Pipeline with data since 2010 rather than their sample file

For those curious about the data, they've also published a notebook detailing a bit more of their methodology.

Happy coding!

thanks. Cant run the algo. I get following error:

Error Runtime exception: UsageNotAllowed: You do not have access to the following dataset(s): logitbot.precog_top_500_free (enable access at https://www.quantopian.com/data/logitbot/precog_top_500 )

when going to the link there is no button to enable access for free dates specified available for free

Joe the Logitbot data is not available for free - it is premium data and you would need to pay for a subscription.

Thanks for the response, however, this is not what is written in the link https://www.quantopian.com/data/logitbot/precog_top_500

it says "Free data availability 01 Jan 2010 - 28 Sep 2016", it just they dont give a way to activate it, seems like bug.

You're right Joe, I missed that.

@Seong - I just tested it up until 27th Sep and it worked - thanks.

thanks, now it works. I just re-run the algo as is and the results are very bad and differen from the above. something is wrong with the data . Seong, can you please check ?

To figure out what secret ML Long-Short part of the algo is making itself, just replace TLT by SHV and compared to 3 month TBill ETF SHY.
Conclusion: Not accounting borrowing costs ML Long-Short part making less then SHY and more volatile.
Do not recommend anybody to use this ($135/month) junk.

Vladimir,

Thanks for taking the time to look into it, the logic of the strategy definitely seems to be volatile!

I think our goal with this example strategy, was just that, an example. We fully believe that folks like yourselves are much more capable of building fully fledged algorithms and hope to do so!

Thanks again for your feedback, and if you had thoughts on how to improve the logic of this strategy, we'd love to hear it!!

@joe - Your performance might be impacted because of the smaller capital size and different backtest time frame

Thanks for all the feedback! Again, this is more of a showcase of how to implement and use the data with pipeline in the IDE. By no means is this a robust trading strategy - just an example of how to incorporate Logitbot's signals.
