With version 2.2.1 of TheBooks, the Data Manager has come of age. This release has transformed the Data Manager from being simply an historic data repository and continuous contract builder into a research tool for futures traders which allows the combining and manipulation of data never seen before in commercial data management software.

The 2.2.1 release of TheBooks adds the following features to the Data Manager:
Even though DMAXX spent considerable effort on these enhancements, the features of the Data Manager that had set it apart from other data management applications have been retained and enhanced as well. These include:
Derived Data Sources
Derived Data Sources are an exciting new feature introduced in the 2.2.1 release of TheBooks. A Derived Data Source is a Data Source whose underlying data comes from one or more other Historic, Continuous Contract, or Derived Data sources combined using user-defined or pre-defined transformations. Once a Derived Data Source has been constructed, it can be used to like any historic data source or continuous contract.
There are four types of Derived Data Sources:
Ratio
A Ratio data source is simply the ratio of two underlying data sources. The numerator bar is divided by the denominator bar. This can be used to provide a relative strength data stream between the two instruments or can be used to create FX cross rates from two data streams of FX rates.
Index
An Index data source is the weighted sum of all the underlying data sources. For example, a user could define an Index-type derived data source as being a basket the major long-term interest rate futures contracts (US and foreign) and weight each as desired. The data stream would be the weighted sum of each of the underlying stream’s Open, High, Low, and Close. The trader could then track the index and Buy/Sell the basket of contracts as appropriate.
Term-Infused Spot
A Term-Infused Spot data source is a way to insert the term structure of continuous contract futures data into a data stream of daily spot prices. This provides a way to produce both outright and cross-rate historic price data that contains both a valid daily price range and term structure where currently the historic data does not exist. It uses an Historic Data Source which is an outright or cross-rate spot rate and a Continuous Contract.
User-Defined
A user-defined data source is a way for the user to apply his/her own transformations between two or more data sources. These transformations can include logical as well as numeric expressions, allowing to you perform operations such as splicing two data streams together at a specific date or comparing data streams from multiple sources and using the values from the stream that make the most sense on a given date within the data.
Summary
The Data Manager has evolved into a premier data management tool for the professional futures trader and researcher. These new features and those to come are designed to facilitate better research and better trading. It you are not using the data manager in your operation, now is the time to review its capabilities again.
