Oops,
This message became a mess as Yahoo apparently removed most of the
spaces, destroying the layout..
Results in the format (Sample, Profit, No. of Trades) are:
(IS1,533,1) (OOS1,1126,2) (IS2,474,1) (OOS2,-537,2) (IS3,43,1)
(OOS3,784,2).
I hope this comes out a bit clearer!

this is a worry since exhaustive optimization is used, and the time
periods are the same. Can anyone offer an explanation? Would it lie in
the way profit is handled when a trade is not completed by the end of
the selected period?
