Re: [amibroker] Perfect Profit and DOF

Dennis,

just another thought: My remark that I want to add ME as an additional 
metric in the Custom Backtester is actually not precisely what I want. 
I've recently started a new thread here called "IS and OOS equity 
curves revisited". My ultimate goal is to add some analytical insight 
to the *concatenated* IS and (particularly) OOS equity curves - and I'm 
afraid this can't be done via the Custom Backtester. Adding, e.g., 
K-ratio and CAR is relatively easy - see my posts in that thread 
(#123921 and 123945). Adding ME is a little bit more challenging ...;-)

Regards,

Thomas
