What timeframe charts do you like to trade?Yes, the key is how good your edge is. I see it as an ever improving process. For example, after 10 years of watching the market I can see the market relatively well for 10% of the time. In the future, it will grow to 20% and so on.
I agree the risk management and discipline are just basic and essential requirements but not sufficient conditions for a consistent winning strategy. The edge is.
