DislikedInteresting, I have this implicit distrust of back testing metrics, I have just never been able to make anything work despite large samples etc.
Have you read the book 'Evidence Based Technical Analysis'?Ignored
This is always refreshing test: Try 4 week breakout on 20 years of data on all majors. Stoploss is always last weeks low. Use fractional risk, for example 2% per trade.
Just a counterquestion, have you read Toby Crabels "Day Trading With Short Term Price Patterns and Opening Range Breakout". Do you know why no reprints were made even though it was a really good book [and a lot ahead its time]? Also check what he has done after he published the book [if you don't already know].
I would also warmly recommend a book with really stupid name "the ultimate trading guide". It's written by futures truth guys who have tracked systems for many many years. In some ways I think some things covered by book should not be there as I assume they have NDAs with system developers but it's a very good read.
