I believe that having a solid trading plan is key to your success. To develop a solid trading plan you must understand to some level, Technical Analysis, Trading Psychology, and Trading Emotions. Without knowledge in those three areas you will not have the confidence to trade successfully.
Without confidence in your trading you emotions will take control. You will be scared to take you next trade or will get out of your trade early when it go against you. These thing will cost you money.
Taking the time to answer these question will help you to find where your mental state is in your trading.
Let get start.
