How can discretionary traders do meaningful backtesting?
I don't see how backtesting is reliable for anything other than very mechanical strategies.
I have a set of criteria that needs to be met before entries, but outside of my criteria - a lot of it has to do with the current "feel" of the market or other intangibles that can't be coded into a script.
How do other discretionary traders backtest? Or do most not bother with it?
