Quantitative Gems: Thanksgiving Rally

Using Cincom Smalltalk to re-create Jay’s Study

Have you seen the Quantitative Gems? This new series of screencasts is an introduction to Quantitative Analysis (QA)—a technique that uses mathematical and statistical modeling, measurement and research to understand behavior. The screencasts include guided examples of how to do Quantitative Analysis as well as creating charts and indicators in Cincom Smalltalk. This series will also walk you through how to build algorithms and interactive charts. The code scripts can be run in our Windows-centric ObjectStudio product or our cross-platform VisualWorks product. The code is almost identical for both, and we walk you through exactly how to do it in either (or both!).

Those looking to reskill or upskill in Quantitative Analysis can learn more and watch the whole library here.

This month’s new Quantitative Gem shows how to use Cincom Smalltalk to re-create a study in a small amount of code. Jay’s study uses the Dow Jones Industrial Average, two days before and one day after Thanksgiving. The study and description can be found here:

In this screencast, we also discuss some best practices using Smalltalk.
