The backtest files where made consistent in their arguments. So please, if you find that there had been some mistakes in this convergence, highlight these and we shall fix it. But not by converting to the old version but to an improved version that remains consistent with the other scripts.
the conservative among us might endorse an alternative methodology: first do no harm and secondly consider each script a standalone application since this 'made consistent in their arguments' effort has been shown in the past to be defective, primarily due to unintended consequences, the change should be un-done by renaming the current 'improved' backtest_multi.pl to something other than backtest_multi.pl and the old original version restored as backtest_multi.pl. then, if users of the original backtest_multi.pl want to embrace any of the improvements or make additional enhancements that's fine, but that should be done on a consensus basis, grounded in an adequately exposed and discussed testing methodology that shows the api is unaffected or demonstrates the changes for all to consider. finally, pod should be included and be consistent with the applications' operation. but readers do note that i completely endorse the principle that gt applications should be consistent in their arguments however, it should be applied only when and where applicable. most importantly it shouldn't change the user api of an *existing* script. if it does and the author cannot make it backwards compatible with the original api then the application should get an alternate name. the passage of time will demonstrate which of the two versions is the most useful. ras
There is no usage of an xml format anywhere else, so we should avoid that or provide it as an alternative everywhere... Th. fr.gamberale

hi again, as i wrote in a previous post im still using an old version of GT. Reading the history of mailing list i noticed that the backtest_multi.pl was changed because nobody know the format of xml file. I use the old backtest_multi.pl quite a lot and can give examples of the xml file format. I can use the new one without problems but the new format doesnt fit to thebacktest_multi.pl logic: in backtest_multi.pl you need only one MoneyManagement for all the systems, inthe old format you had a xml fileld different from the system definition, in the new one you have to define MM only on the last system line, otherwise backtest_multi.pl gives an error. before i change all my other programs that use the xml format id like to know if what i wrote will make restore the previous version of backtest_multi.pl or is not enough important.
