I know this is a recurring theme, but what could possibly be the basis for anyone considering that ANY commercially marketed trading system is worthwhile?
If YOU (any trader) did find the Holy Grail, would you codify it, develop it, find marketing outlets, market it and print brochures, flyers and run seminars involving travel and time and all the boring non-trading effort that entails...
OR
...would you simply trade it?
I'm not saying that most commercial trading systems are a waste of time.
I'm saying the good things you get from them (the gems) are probably accidental and may even in the long run be worth the cost of the system/seminar etc.
But really, who would rather market their system rather than trade it - themselves - alone.
