If you were to ask today, what do you think is the most important document that you need to have if you are going to establish your own business? You might say, permits, legal documents or others that are important in your opinion. But the real thing is, you need to have a well written business plan to help you manage your business soon. This is where your strategies go and how you are planning to move your business to a successful direction.
As for trading, it is the trading plan that is the most important piece of document that you should have as soon as you start working as a trader/ You can place all your strategies there and have your game plan be included as well. It is highly recommended that you write your own trading plan so that you really can claim the strategies that you have written there, especially as you experience that you are really getting some good returns on your trades.
