The BTWFMgr Walk Forward(WF) Analysis offers several additional diagnostic options
shown within the Walk Forward(WF) Optimization parameter window:
I
For each Walk Forward analysis a WF base folder is created with the name combining the Period definition, Filer and sort definition:
Example: P[1C_1C]+F[PFMin]+S[SortMix1] - combines:
P[1C_1C] (Custom Period Definition#1)
F[PFMin] (Filter Definition: PFMin)
S[SortMix1] (Sort Definition SortMix1)

As each WF Period is processed - the logfile shows:
Starting Period#001 (ISA 20090801 -> 20090831) 
etc...
and the status window in the WF optimization box shows:
Period#1(1C_1C): Range#1: 20090801 to 20090831 - Calculating 11 Trading Permutations
etc...

Save Optimization Run Results Creates a spreadsheet(CSV) with the period In/OutSample details for each WF DateRange/Period  The files are in a new sub folder for each period variation below the WF base folder with a CSV file for each optimization permutation: P001[1C_1C]+F[PFMin]+S[SortMix1]/OPT0000001_P001_F0001_S0001.csv ... until the last WF Optimization - for example: P001[1C_1C]+F[PFMin]+S[SortMix1]/OPT0000028_P001_F0007_S0004.csv Click here for an example of a optimization result file OPT0000001_P001_F0001_S0001.csv (Open in MS Excel) INI Setting: SaveDateRngSet - Flag: WFO_FLG_SAVEDATERNGSET

Filter+Sort Details  Creates a spreadsheet(CSV) with the list of trade permutations which passed the filter! The candidates which survived the filter are sorted by the requested sort criteria and the show also current filter value(s). Click here for en example (OPT0000001_P001_F0001_S0001_Rng001_20090801.csv) all files of a run here (Hits.zip) for each WF Optimization AND WF/date period a new file is created in a new sub folder "Hits" INI Setting: SaveOptPerm - Flag: WFO_FLG_SAVEOPTPERM

Tracking WalkFwd Filter FAIL/PASS Results You can also track the WalkFwd Filter process - simply define the filter variable to be monitored In the C:/BTWFMgr/ BTWFMgr.ini configuration file - Example [BTWFMGR] WFTrackVariable=$PF Example:   WFTrackVariable=$TrdPerYr   Which will create a diagnostic file: C:/BTWFMgr/TrackFilter.txt showing the variable value for all filter calculations - with the filter PASS/FAIL results: FAIL: Perm#000001 $TrdPerYr= 58.7009 StartDate=20131231 EndDate=20140224 WFOpt#0001 FAIL: Perm#000002 $TrdPerYr= 65.2232 StartDate=20131231 EndDate=20140224 WFOpt#0001 FAIL: Perm#000003 $TrdPerYr= 58.7009 StartDate=20131231 EndDate=20140224 WFOpt#0001 ...

Range+Permutation (very detailed) Creates a spreadsheet(CSV) with the list of all trade permutations details Click here for en example (Rng0001_20090801_20090831.csv)  for each WF Optimization Preiod in  a new file is created in a new sub folder "TradePermutations" INI Setting: SaveTrdPerm - Flag: WFO_FLG_SAVETRDPERM

Run Log  Creates a spreadsheet(CSV) with the list of all the WF optimzations and statistics INI Setting: SaveRunLog - Flag: WFO_FLG_SAVERUNLOG
