Quote from NoWorries:
I think the problem with constructing a portfolio of trading systems is, that it can create a false sense of security.
It is quite easy to get a nice looking portfolio equity curve from a bunch of bad systems. Because the portfolio curve looks nice, you think you're on to something, while in fact you're trading just a bunch of bad systems. It's still garbage in, garbage out in that case.
My criteria are that any system I trade has to have excellent reward/risk statistics by itself and a sufficient history to make these statistics meaningful (e.g. at least a year). I always ask the question: Would I feel confident trading this system all by itself with my entire trading capital. If the answer is "yes", I'm happy to include it in my portfolio of trading systems.
Again good argument - the "Would I feel confident trading this system all by itself with my entire trading capital" - rule ... great.
