What if to rename WDO$D history files to WDOK18X and while training use History = "X.t6";
----
History
The last part of the file name - including extension - of the historical data files; for selecting between different sets of price histories for the same asset. If not set up otherwise, the files begin with the asset name and year number, and end with ".t6". Examples: History = "fxcm.t6" reads price history from f.i. EURUSD_2015fxcm.t6; History = ".t1" reads T1 price history from EURUSD_2015.t1. History must be set before calling asset().
