Re: backtesting daylight only futures trading systems

Marshall,
I spend $1500, for a software, which enables me, to work on RT charts, in a
way, I developed, and which is my personal trading style.
Maybe MetaStock was designed for end of day, but to me it makes no
difference, if I trade 5min or weekly charts...
For me, it`s just fine for real-time!
And to get personal:
People out there try to slaughter me every day, and if I would use a system,
that was delivered in a mass-product, I would be a fair prey.
To survive these attacks, is no question of money, but of a view for the
reality of the markets.
By the way, I think, that Glen`s answer to your original post is worth a
multiple of $1500...
regards,
Nicholas Bodeux
