well, that one of the best equity curves i have ever seen, 
but not the ideal, since it is near linear and not exponential,
although the latter might be due to no pyramiding in which case 
it is near ideal. congrats.
was wondering if you could post the stats for the system?
and is this really an adaptive system?
bilo.

It depends upon how linear the equity curve is in backtesting over
several years.

A good clean curve such as the attached shows no sign of "getting tired".

This depends a lot upon how adaptive the system code is. A good
adaptive system should work for a long time.
