Well, I've been trading since 1992 and I'm still here and I'm profitable.
I'd call that real time results.  Will I provide an audited proof?  To the
IRS if I have to.  But not to just anyone - if you choose not to believe me
you can just as easily question the basis of my trades even if you I give
you a blow by blow account via audited statements.

As hans says ...  I'm not selling a system.  I don't care whether or not I'm
believed.  But I claim it can be done but not necessarily by everyone.  I
presume from your statement, you fall into the later group - we clearly have
different trading styles.  (My statement is not intended to demeen you (you
may be a better trader than I) - it is just an observation of style).
