TradingSolutions v1.21 Build 010522 is now available from NeuroDimension. The current build fixes minor problems encountered in the initial release of Version 1.2. A patch is available to upgrade most previous versions and builds of TradingSolutions to the current build.
Version 1.21 also adds over 60 new built-in functions:
* A new Signal Filters function group, including new trade stop simulations.
* A new Constant Values function group with commonly used constant values.
* New Signal Processing functions, including Bars Since Entry.
* New Series Sampling functions, including states since a condition was last true.
* New Variable Length series functions to allow more flexible series processing.
* New Date functions, including Days Since Date and Value On Date.
* Average True Range Bars functions.
* A Linear Regression Period Intercept function.
Upgrading to the new build is free for current customers. No additional activation codes are required to upgrade to the new version. Simply install the upgrade and start enjoying the new features. Users of the free evaluation version can also upgrade to this new build.
For information on upgrading to the latest version, as well as a complete list of the changes made in this build, see http://www.tradingsolutions.com/download/updates.html
You can determine the current version and build of your TradingSolutions installation by selecting About TradingSolutions from the Help menu.
The grand opening of the TradingSolutions Financial Bookstore was last month and it was very successful. To celebrate, we’re offering three free titles with every order from our bookstore before the end of May. You’ll get the following titles FREE with your purchase:
* Technical Analysis Simplified (a $29.95 value)
* Day Trading Wizard on audio tape (worth $19.95)
* Secret of SOES Bandit (a $29.95 value)
That’s an $80 dollar value, FREE with your order. To take advantage of this special offer, use the following link to enter our bookstore and place an order:
Backing Up Your Work
TradingSolutions stores all of your data, functions, and trained predictions in a single directory called the “Work” directory. By default, this is a subdirectory named “Work” in the directory where you installed TradingSolutions. Typically, this means you can locate at:
If you would like to back up your TradingSolutions data and calculations, simply back up the Work subdirectory. If you would prefer a smaller backup, you can back up the fields you need for creating the signals that you trade by creating trading solutions for each of those fields (including the weights), exporting these solutions, and backing up only the exported solution files.
Using Multiple Work Directories
TradingSolutions can use multiple Work directories. This is useful for keeping the stocks you are trading separate from large numbers of stocks you may occasionally scan for good models. To switch between two work directories, select “Change Work Directory…” from the File menu. To create a new Work directory, simply use Windows to create an empty folder and point to it with “Change Work Directory…”.
Labeling Work Directories
Each time TradingSolutions is opened, it opens to the Work directory it was using the last time it was run. If you have multiple Work directories with similar contents, it can sometimes be a little confusing which Work directory you are starting out in. To visually label which Work directory you are currently in, try renaming “My Portfolio” to a new name, like “Active Portfolio” or “Research Portfolio”.
Using the Default Models
When you create a new prediction in TradingSolutions, the Predict a Value Wizard automatically selects the best model and settings for most predictions. However, with a little experimentation, you can often find better models for specific sets of data. This month’s feature spotlight covers some of the alternative models that are available.
TradingSolutions includes state-of-the-art neural networks designed specifically for use with time-series data, like that of the stock market. They include memory directly in the model that helps the network to detect patterns in the sequencing of the data. Most of the predictions created in TradingSolutions default to this type of network. Therefore, adjusting the model type is often not necessary.
The simplest type of memory used in the neural network models can be simulated by manually adding lags of the inputs to the prediction. For example, instead of using only the percent change in the closing price, you could use the last five percent changes in the closing price. When these types of inputs are detected, a more basic neural network model is used to avoid unwanted redundant processing.
This basic neural network model is called a Multi-Layer Perceptron (MLP). TradingSolutions includes several offshoots from this basic model that allow for more specialized processing. For example, modular networks contain multiple processing paths, allowing different paths to specialize on different aspects of the data. Feedforward variations of these networks allow some of the data to bypass sections of the processing so that both the raw and processed values of the data can be evaluated later in the network.
The default time-lag networks used in TradingSolutions keep the most recent values in buffers to help the network identify patterns. An alternative to this type of memory is available in recurrent networks, which echo the last processed values back through the network to be used in the processing of the next value. Due to its different approach to memory, these types of models may be better suited to longer term trends.
The TradingSolutions Suite
TradingSolutions includes over 50 variations of 5 different neural network models. However, you are not limited to using only these models. The TradingSolutions Suite, which includes NeuroSolutions and the Custom Solution Wizard, allows you to build your own specialized neural models using a graphical user interface and helpful design wizards. Experiment with Principal Component Analysis networks, fuzzy logic, and other technologies, then train and use your creations directly in TradingSolutions.
Many TradingSolutions users read Technical Analysis of Stocks and Commodities (TASC), the Traders’ Magazine. It’s a great way to trade smarter with detailed information on trading strategies, charting patterns, indicators, and computerized trading methods. As a free service to our users, we arrange for the “Traders’ Tips” section of the magazine to include tips and techniques for implementing many of the indicators found in the magazine in TradingSolutions.
Each time a tip is included in the magazine, we also include the implemented functions in the Solution Library on our web site. These functions can be imported into either the full version or the evaluation version of TradingSolutions and are completely free. Visit the Solution Library now at: http://www.tradingsolutions.com/download/solution.html
If you aren’t familiar with Technical Analysis of Stocks and Commodities, we encourage you to visit their web site at: http://www.traders.com
