This sounds like a great idea: generate accounting and performance numbers for managed accounts and funds by reading broker statements.
On the surface, it is a great idea; unfortunately, it is not likely to succeed in the context of a CTA or hedge fund that trades futures and/or FX; not to mention over the counter instruments such as swaps.
There are several reasons why this can’t work reliably. The most notable are:
Another problem that believing what is on a statement causes is it defeats the whole concept of reconciliation. By accepting what is on a statement, the advisor is in effect, doing the same thing as never balancing a checkbook.
In the case of an investment manager, he is being paid to manage the money of his investors. It is the manager’s responsibility to ensure that trades are booked in the correct account at the correct price, that positions are accurate and balances are in line. Basing accounting on the contents of the statements bypasses these important checks.
A better approach
If you assume an investment manager must maintain the list of trades she has made as well as her open positions in order to effectively run her business, she is already most of the way to being able to produce the required financial performance records.
A system like TheBooks is designed to take advantage of this fact. It provides simplified recording and reporting of trades and automatically keeps track of positions (both net to the street as well as by system/strategy) and it generates the appropriate accounting entries resulting from those trades and open positions.
A clear advantage of this is that reconciliation can be performed at the trade, position, and cash balance levels (another capability of TheBooks). In addition, because commission, fee, and interest accruals are also performed by TheBooks, the resulting accounting and performance reporting numbers are accurate.
Another advantage to performing your own accounting rather than basing it on the contents of broker statements is time. If accounting/reporting is based on broker statements, there is no easy way to provide end of day performance reports. All reporting must wait until the statements are received; typically early the next day.
TheBooks reporting is based on the trades that have been posted and the market prices as they are now. This means that end of day reports detailing daily/monthly/annual performance (summarized or detailed by sector and/or market) can be sent automatically at the end of the trading day; significantly improving the level or reporting and transparency an advisor can provide to her clients.
Summary
An advisor must maintain a record of his trading activity. Using a system like TheBooks not only maintains a record of all trades, it maintains positions and generates all the performance and accounting records required in a way that delivers more accurate and timely reports than those that can be produced by using broker statements.
Beyond that, it provides the basis for robust trade, position, and cash balance reconciliation, helping the advisor manage the inevitable trade and position discrepancies that occur when trading futures and FX.
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.
A subject which we have getting a lot of questions about is the use of virtual machines. We at DMAXX have been using virtual machines in our operation for more than three years. In fact, we are so dependant on them that virtually everything in our network is a virtual machine. It is safe to say we could no longer operate effectively without them.
We use VMWare in our operation and have effectively virtualized all of our systems with the exception of our primary domain controllers and our SQL Servers.
Our use of virtual machines can be grouped into three major categories:
Development/Testing
Because we usually have at least two and sometimes three versions of TheBooks in the field at once, having separate build and test systems for each version is a must. Virtual machines allow us to maintain these systems within the context of a single large server without the need to maintain separate systems for each version.
In addition, installation testing is much easier as starting with fresh version of an operating system is simply a matter of copying some files.
Production
The use of virtual machines allows us to segment functionality within our network to the point where each system performs a single function. This makes maintenance and upgrades much easier. It also allows the movement of servers from one physical computing platform to another by simply moving the files which represent the virtual machine.
Hardware upgrades become much easier as upgrading a single platform results in the upgrade of all virtual machines resident on that system.
Disaster Recover
Another huge benefit of the virtual machine environment is in the disaster recovery area. Because the functionality within the network becomes portable, the ability to implement remote sites becomes greatly simplified.
Each of our VMWare host servers have backup scripts which iterate their inventory of virtual machines and one-by-one shuts down a VM backs up its configuration (virtual disks, hardware configuration, etc) to an NAS storage array and then re-starts the VM.
The NAS storage array is replicated to a remote location which also houses VMWare servers. If the primary site goes down, the replicated virtual machines can be started at the remote locating in a matter of a few minutes.
Virtual Machines and TheBooks
Needless it say, TheBooks will operate just fine within a virtual machine environment; all of our testing is done that way. We do, however, suggest the following guidelines:
Business continuity and disaster recovery has become an essential aspect of running a successful investment manager. The existence of a backup operating environment is now a key requirement of all due diligence questionnaires.
The ability to easily configure and manage systems so they can operate in production or backup modes is an important consideration when evaluating mission-critical applications.
Startup Profiles
TheBooks incorporates a concept called Startup Profiles which are a set of system parameters describing how the system is to behave. Startup profiles describe things like the email server to communicate with, the price feed computer, and other system-related information.
TheBooks allows you to define multiple startup profiles. These are maintained within TheBooks database. Each server that runs TheBooks can be assigned a different startup profile to use when it starts, allowing you to configure a startup profile for your production environment and a startup profile for your backup environment from your production environment.
When TheBooks database is restored in your backup environment, the settings appropriate to the backup environment are used.
Licensing
Because DMAXX recognizes that an offsite backup facility is a requirement of your business, your license to use TheBooks® allows you to maintain as many offsite backup facilities you need at no additional charge.
Offsite Backups
As an optional feature, TheBooks can automatically back itself up and copy the backups to one of DMAXX’s servers for secure, offsite backup.
