I am a big fan of Keras – Fortunately we also have a similar framework available when we need to implement a solution which works in the JVM: DeepLearning4J. In this Blog I give a quick introduction of some of the key concepts which are needed to get started. I am using the Iris dataset to demonstrate the classification of data with the help of a neural network. This demo has been implemented in Scala Read more
Hurray – Today I finally managed to finish the implementation of the integration into E-Trade. Unfortunately it turned out to be a little bit more complicated then initially thought and there were quite a few stumbling blocks around the topic of “authentication”. I have aleady demonstrated how to do trading with actual data. In this document I want to show how to do automatic trading with E-Trade. Information on how to request to access E-Trade Read more
Because Investor has been implemented in Java and is available as jars from a Maven repository we can easily use the framework in all languages which are based on the the JVM. Here is a quick demo using Jupyter Lab (using Beakerx) with: – Scala – Java – Groovy – Kotlin – Clojure Here is a screen shot of Jupyter Lab: Scala Scala combines object-oriented and functional programming in one concise, high-level language. Scala’s static Read more
So far we have looked at the trading simulation functionality which was using the historic stock data to evaluate strategies on a single stock or a portfolio of stocks. In this document we want to demonstrate how to do trading with actual data. We still use the PaperTrader to demonstrate the basic logic Setup We add the necessary jars and import all relevant packages: %classpath config resolver maven-public https://software.pschatzmann.ch/repository/maven-public/ %%classpath add mvn ch.pschatzmann:investor:0.9-SNAPSHOT ch.pschatzmann:jupyter-jdk-extensions:0.0.1-SNAPSHOT Added Read more
In this document we demonstrate how to use the Edgar Database for the selection of the stocks into a portfilio with the help of the Investor library. This functionality is using the Edgar Webservice which is based on the data which is available on https://www.sec.gov/edgar.shtml. Setup We add the necessary jars and import the related packages. %classpath config resolver maven-public http://software.pschatzmann.ch/repository/maven-public/ %classpath add mvn ch.pschatzmann:investor:0.9-SNAPSHOT %classpath add mvn ch.pschatzmann:jupyter-jdk-extensions:0.0.1-SNAPSHOT // our stock evaluation framwork import Read more
Our Mobile Phone Companies here in Switzerland are providing fast unlimited Internet access at competitive prices. So I was considering to switch from my Cable Network to a pure Mobile access.

Processing a Portfolio of Stocks This project provides an easy to use functionality to implement and evaluate automatic stock trading strategies. It is implemented in java and therefore can be used in any environment which builds on the JVM. It provides the following functionality: – Simple access to stock data – Declarative formulation of trading strategies – Evaluation of trading strategies – Optimization of trading strategies – Support of portfolio of multiple stocks / trading Read more
