agree with dc2000.
if you allow them the benefit of the doubt for that peculiar error of -359 (can happen to anyone), and also consider the +283 as an anomoly, the general returns per day are about 30-40 pips per day from looking at 11 pairs.
They have only had 2 days where the total pips exceeded 100 pips. (not counting Sep-21)
you would be better off trading hans123, where they exceed the above results by only trading 2 pairs.
(treating hans123 as a sort of baseline, since:
they have been around for a long time,
and they update regularly,
are evolving continuously,
a freely distributed system,
and there is a big enough following to prevent deliberately skewered results.)
You cannot consider the +317 as being truly representative of their overall results.
EDIT: got dc2000 name wrong!. (missed a zero.)
