Any 100% automated system offered to the public is destined to fail. That is an absolute rule, no exceptions.
Whenever you hear - read about a fully automated approach where everyone gets the exact-same signals each time, there is no possible way it can succeed.
Take the ER2 for example. If someone tries to market a mechanical system for that, what will happen? Enough system buyers to absolutely overwhelm the signals is guaranteed.
Try filling 300 ER contracts at 824.40 in group-grope fashion where everyone gets the same signal. Limit orders would fill 10 to 50 contracts at most. Everyone else pounds salt with no fill while watching intended trade run away. Market orders would complete the fill several ticks to couple handles away from 24.40 intended.
Black-box mechanical systems must be protected from disclosure, or they are doomed to fail.
Austin,
With all due respect, you chose a specific example that doesn't apply in general terms. Of course the ER2 will slip under heavy pressure. That's the nature of the instrument - low liquidity at certain prices. Also, I assume you are talking about scalping, or in general, a very short time frame where the price moves provide opportunity for smaller sized lots. All these issues are things to avoid when looking at a tradeable system - they all do not allow for scalability.
I trade a very scalable self developed system that could probably handle 100x the size I currently trade it with and I am looking into providing an advisory service for a very small number of clients. The facts about disclosure scares me (i.e. I do not want to provide any details about how this thing trades), but, I know for a fact it can handle a good amount of added size and the potential for large scale funding also interests me.
My bias as a "wanna be" signal provider most likely makes my post more suspect, but, I do believe people can trade signals given a certain time frame minimum (I'd say 10 minutes or more) on liquid instruments.
Out of curiosity, what are your (or anyone else's) thoughts on collective2.com?
