New Knowledge Base will be released today

Dear All,

We are revamping our Knowledge Base which is quite old, and frankly has many articles that are terrible, not useful at all, deprecated, or plain wrong.

It’s a work in progress but we’re committed to having a KB that is top notch. Some articles are new and some are the old ones that will be rewritten. We have also fixed some of the issues with the more advanced articles in the Library that were poorly formatted and unreadable.

It will be fully integrated by tomorrow. In the meantime you can access two ways:

  1. From the Chat widget by doing a search
  2. In this address https://portfolio123.customerly.help/

Let us know your thoughts and what things you’d like added to the KB

Thank You!

NOTE: the old KB is still accessible from the support icon on the top right.


We plan to have many more “How To” articles like this one How to Automate your Research with DataMiner that lead you to something quickly.

And more images of course.

Sometimes the most frustrating thing of a new tool is just knowing where stuff is.

Thanks Marco, appreciate this update. Welcome news.

Very nice. Much needed.

Marco, while reading through the new knowledge base material I ran across this in the “curve fitting” section of the “backtest bias” page.

“For this bias we can only give you tools and tips to combat it. You can for example rerun the strategy excluding all the stocks that were used in a previous run. A serious degradation in performance is a sign of curve fitting. We also have more advanced tools like rolling simulations.”

Can you explain how the rolling simulation combats curve fitting?

Thanks
Tony

Simulations have a set starting and ending date, and a great deal of your return will depend on those dates. The Rolling Tests vary the dates and can therefore give you much richer and more robust results.
