brownsfan,
Several years ago when I first started trading, I did go at it live for a while. The problem I ran into was I had no way of knowing for sure if the patterns I was trying to trade really had an edge.... too many variables.. everything from emotions to violating rules.. etc.. would have winning streaks, losing streaks.. but in the end I had no idea if what I was doing had an edge. Which lead me to the conclusion, why trade something without thoroughly backtesting it? Its easy to have huge winning streaks just by pure random chance....I want to see years of results through all sorts of market conditions to know if the edge is simply random chance....hence backtesting...So naturally if I can backtest a given strategy, why trade it at all.. just automate it... hence where I am today.
I may be trying to automate instead of trading discretionary... but I do get a LOT of screen time everyday due to a job that has no problem with me watching the market while working...My strategies are not just random strategies created by "throwing indicators at a wall"..... A lot of them have basis in what I see from this screentime and market replays after hours...
For instance i'm looking to set up a new strategy now. So i'm currently looking through lots of charts of range bars since I am unfamiliar with how the market normally moves using range bars..
