Just as having an objective target price for each trade you enter helps you to stay disciplined to your trading plan, setting personal goals of what you want to achieve helps to cultivates focus and maintain a clear vision of where you’re going. Having written goals to aim for allows you to measure and make improvements to your performance and stay on track.
Decide on the returns you want to achieve in the timeframes that suits you. For example, if you hold positions for long term growth, set yourself yearly goals to aim towards. If you’re a short term trader, have monthly or quaterly targets to aim towards.
One of the best books I’ve read about how to set and achieve your trading goals is ‘Trading in the Zone’ by Ari Kiev.
