Re: buy and hold results change

[cliffelion@xxxx]

Hi David,

I am using the same timeframe, stocks and analysis settings. When I 
change systems the analysis results change as expected - but so do 
the buy and hold results. I want to use the buy and hold as the 
baseline to compare the different systems so I'm not sure how to 
compare the systems when the buy and hold results change.

AMI may be using the buy point of the system to start the buy and 
hold calculation - which means that the system is influencing the buy 
and hold.

This may be OK - but I would be interested to know if there are other 
methods for comparing systems.

Regards,

Cliff
