'Best Trade' could mean a lot of different things to different people.
For some it could simply mean a ticket that has a large number of +PIPS profit, for others it could have been a series of trades providing coverage of bad tickets with good tickets which ultimately provide for an aggregate profitable basket.
Success and Best are subjective to ones own viewpoint. :)
If it looks too good to be true, it's probably a scam! Let the buyer beware.
