NEW YORK (TheGoldAndOilGuy.com) -- Many investors and traders make the same mistakes, assuming that one needs a complex trading system to consistently profit from the stock market.On the contrary, some of the top-performing strategies are the ones with the fewest moving parts and are simple. Because of their simplicity, they can be easily and consistently followed. The methodologies we use for timing the market, picking stocks and option trades are very simple because we focus mainly on price, volume and momentum. These three indicators are the key to success. When these are used together, you are able time your entries and exits during key turning points and clearly define risk and reward levels while maintaining a clear unbiased state of mind, which allows one to trade almost emotionless. As my Trading System Mastery coach ( Brian McAboy) taught me, if you do not have a detailed trading plan that a five-year-old could trade, then you do not have a solid strategy and will have unnecessary losses and emotional stress.
