Successful trading requires lots of preparations and practices. What you have mentioned are, just the 50% of successful trading requirements and the remaining parts are belonging to how intensively you are preparing. These days people are easily gaining knowledge from various resources but they never turn as a successful traders due to lack of real market exposure.

In my experiences, for staying competitive against ever changing market conditions, we must need to update our strategy and must continuous learn new things. So, traders must never be relaxed and must work hard always to have sustaining success in trading.
