[EquisMetaStock Group] Re: Histrical Testing in SpyGlass

[superfragalist <no_reply@xxxxxxxxxxxxxxx>]

This is a common problem with external relative strength testing.
Regardless of the program you are using, you have to calculate the ERS
for 10% to 15% more bars than the test period.

For 20 years of data, which is a bit much, you'll need something
between 5000 and 6000 ERS data points. 

If you have 20 years of data, how are you compensating for surviorship? 

You would be better off running tests on 5 to 8 years of data in
sample and another 4 to 6 years of out of sample data. 

Good luck! My tests show the ERS value to be one of the best filters
there is for qualifying possible trades.
