Price Action Lab Home The Most Advanced Tool for Analyzing Price Action and Discovering Trading Systems

Tips for demo users

The demo is fully functional except for complete code generation and system tracking. The demo may be used for the purpose of understanding the functionality of the software, like for instance the process of discovering price patterns and building trading systems. There is a time limit on the number of executions (about 30 depending on use and the demo cannot run more than 40 hours straight). We strongly recommend using the demo to become familiar with the program before ordering a license. 

In order to use Price Action Lab to search for patterns, scan for patterns, or for p-indicator calculations, you will need to specify the following on the relevant workspace:

1. A data file with the price history to use. The file must have appropriate format and length.
2. The performance parameters and risk/reward objectives to apply.

The software setup includes sample historical daily and intraday data files in compatible format. These files are located in the DATA subdirectory of the program.

Sample search and scan workspaces are also included in the MYWORK subdirectory. You may open the workspaces and view the parameters specified in them. Results are also included. in RESULTS subdirectory. The format specifications are listed in the help file of the program.

The following two steps are required in order to run a search for price patterns

1. Create a T/S file

This file contains the profit target and stop-loss values to be applied to the search. Each line in a T/S file corresponds to a pair of profit target and stop-loss values used in the back-testing of price patterns for determining historical performance. The values in a T/S file may stand for percentages of the entry price or points added to the entry price and the choice between the two options is made on the search workspace. Sample files can be found in the TRS subdirectory.

2 Create a search workspace

On the workspace you specify the T/S file to use, the historical data file and the trade input and search parameters.

The following two steps are required to set-up a price pattern scan:

1. Create a T/S file

This file contains the profit target and stop-loss values to be applied to the scan. Each line in a T/S file corresponds to a pair of profit target and stop-loss values used in the back-testing of price patterns for determining historical performance. The values in a T/S file may stand for percentages of the entry price or points added to the entry price and the choice between the two options is made on the scan workspace. In the case of exits on the close of the next bar, the values of the T/S file are not taken into account and can be set to anything. Sample files can be found in the TRS subdirectory.

2 Create a scan workspace

On the workspace you specify the T/S file to use, the historical data file and the trade input and scan parameters. Note: in the case that next close (NC) is selected as the exit parameter on a scan workspace, a dummy T/S file must be specified with just one pair of target/stop values but these will not be used by the program.

The following two steps are required to set-up p-Indicator calculations

1. Create a T/S file

This file contains the profit target and stop-loss values to be applied to the calculations. Each line in a T/S file corresponds to a pair of profit target and stop-loss values used in the back-testing of price patterns for determining historical performance. The values in a T/S file may stand for percentages of the entry price or points added to the entry price and the choice between the two options is made on the workspace. In the case of exits on the close of the next bar, the values of the T/S file are not taken into account and can be set to anything. Sample files can be found in the TRS subdirectory.

2 Create a p-Indicator workspace

On the workspace you specify the T/S file to use, the historical data file and the trade input parameters. Note: in the case that next close (NC) is selected as the exit parameter, a dummy T/S file must be specified with just one pair of target/stop values but these will not be used by the program.
 

When creating a search, scan or p-Indicator workspace you may introduce multiple search, scan or p-Indicator lines each with different data file(s), T/S file and parameters.

FAQ: Why is the pattern code generation disabled in the demo version?

For basic evaluation purposes, the search performance parameters and the backtesting parameters of each pattern along with the forward testing capability of the software are in our opinion and experience sufficient for getting an idea of the capabilities of this program. Since there are many alternative and even competing ways of grouping patterns into trading systems using Boolean and other operators and indicators, and in addition there are many possible objectives traders may have in terms of performance, we do not claim to provide complete trading systems but only the building blocks that one can discover after careful use of the program and appropriate analysis.

FAQ: What is the difference between the search and the scan functions ?

The search function discovers all price patterns that satisfy the performance criteria specified on the search workspace, such as a minimum number of trades, a minimum percent profitability (success rate), a minimum profit factor and a maximum number of consecutive losers. The results of this function can be used for grouping patterns into trading systems and storing them in System Tracking for signal generation or for generating code for use with popular trading platforms.

The scan function determines if there are patterns formed as of the close of the last bar in the data file that satisfy the performance criteria specified on the scan workspace. This function is especially useful for scanning a universe of securities, like for example the S&P 500 stocks, or a number of futures contracts. A scan is equivalent to a search with the Search Depth parameter set equal to 1 bar. The scan function can be used to discover new price patterns on a daily basis to add to the database or System Tracking.

Using the search function to discover trading systems together with the scan function on a daily basis for determining the presence of new patterns is the recommended use of the program. As an example, one can use the search function to discover a number of patterns in S&P 500 index mini futures and then add a trading system to System Tracking.. Then, on a daily basis, the updated historical data file can be used in a scan workspace to get the signals from price patterns and compare that to the System Tracking output to determine whether there are some new patterns that were not detected at the time of the search due to not satisfying the performance criteria, or to even identify any long-short signal conflicts.

Note: The best way to become familiar with a program is by actually working with it. There are many ways to use a trading program depending on user's experience and objectives and this also applies in the case of Price Action Lab.
