Price Action Lab v3.0 released on 12/12/2011
PAL v3.0 offers the ultimate method for cross-validation. Click here for more details. Only 50 numbered licenses will be sold.Major addition: Search for
common patterns. The search function can be used to search for patterns in each historical data file specified on a search workspace that are also profitable in all the other historical data files listed on the same
workspace. This is a unique feature that provides the ultimate cross-validation method for making sure that patterns are profitable across a number of markets and instruments. Click here for examples.
Minor addition: Number of distinct patterns and number of files used are now shown on the heading of search and scan results. Price Action Lab v2.5 released on 11/08/2011 Major additions:
(1) Ability to change target and stop values in backtesting mode. The same target/stop type is assumed, inc, pts or NC. Using this new function the sensitivity of the
pattern performance to changing target/stop can be studied without generating code and backtesting in another platform. 
(2) Ability to scan for 3,4,5,6 - Bar patterns only (scan function). 
Minor bug fix:
Fixed the Ninja code generation letter case for O,H,L,C. (MetaTrader code can be used in v2.0 instead).

Major addition: Raw code generation
The raw code generation is a major new feature of v2.0. It allows code to be generated automatically in raw form in a text file from the search and database results for use as an input to neural network,
walk-forward optimizers and other system building products. Each line of the file contains the following:
Pattern Code;File;Type;TradeOn,Target;Stop;C
where File is the filename, Type is LONG or SHORT, TradeOn is Open or Close, Target is the profit target, stop is the stop-loss and C is % or pts. Pattern Code is
the formula code used by the native language of the various supported platforms.
Click here for a screenshot of an example of EasyLanguage raw code generation for a hypothetical security XYZ.
The raw code generation applies only to the Search and Database results. Two files with identical content are saved automatically in sub-directory ...\Results:
(1) A file called GeneratedCode.txt which is overwritten every time new code is generated.
(2) A file with the name: RawCode_mm_dd_yyyy_hh_mm.txt
This file is overwritten only if new code generation takes place during the same minute mm that the file was initially generated.
The text files containing raw code can be deleted using a new tool added to File Maintenance under Results and called "Code .TXT FILES".
Minor enhancements and bug fixes:
This version has two minor bug fixes in the pseudo code generation for short patterns with next close entry and in generated code labels for short patterns.
The minor enhancements include a fix for the problem with the code generation cursor jumping at the beginning of the buffer, a faster screen refresh after maximizing
the application from minimized status, the disabling of the Run button on all workspaces after it is clicked and allowance of a five digit number for the Search Depth.
Beginning with this version, Metastock code generation now includes the delay value and thus the delay in the tester should be set to 1 for Open and 0 for the close.
