Today my account got emptied. € 16.000 euros loss in one year with Z5.

First 4 months, there was around 75% profit. Next 8 months, it ate up the 75% profit plus little more, So far, I considered reasonable in the world of EA's, but when 1.26 went into action started to do strange things closing lots of trades and opening new ones, without taking into consideration the left margin. So no way to keep the 95% rate of success as in back tests. There is something wrong in the money management.

My advice, stay out of Z5.

Independently of 1.26 doing something wrong, previous versions were working reasonable as far as they were tested in favourable periods to the system. In ther words, Walkforward analyssis works as far as it is tested in periods which are favourable to the system but not in periods that are unfavourable, for instante in extreme conditions close to 1,20 in EURCHF or probably on the other extreme up. For a system to be realiable should be tested also in extreme adverse conditions.
