Thanks. Those are all valid points worth remembering. I did make a minor tweak that is helping me stay out of the chop zone for the night.
Truth be told, my understanding of backtesting is rather limited. Sometimes, I wonder if it's worth spending so much time and energy for something that has no guarantee that it would work.
Backtesting is very important for me. That was how I found some statistical edges/market behaviours which I use. Through backtesting you will also know if your 'ideas' have positive expectancy.
