>>maybe your comments will help some and prompt others who disagree to provide

When it comes to probability, the only proof I know centers around the Law of 
Large Numbers, but its too large to be useful here.

How about this as food for thought....

If, as is suggested, that the market's behavior one year has not much to do 
with any other (or something like that) then it would follow that it should be 
nearly impossible for a simple trading system, that makes about 1 trade/month 
to be profitable over a 10-15 year period.  But it can be done.  Therefore, 
something must be wrong with the premise.
