optimization

["Ermanno" <cooprimavera@xxxx>]

Hello, tanks for your help and excuse me for my poor english :-(

I would like to optimize the following formula but I am not able..


buy=cross(c, ma(c,5)+stdev(c,10));
sell=cross(ma(c,5),c);

every optimization gives the same results, I would like to optmize the
arraies of ma(c,5) and stdev(c,10),

how can I do?

Thank you,
Ermanno
