Many experienced and successful traders are also excellent at keeping records. If they win a trade, they want to know exactly why and how. More importantly, they want to know the same when they lose, so they don’t repeat unnecessary mistakes. Write down details such as targets, the entry and exit of each trade, the time, support and resistance levels, daily opening range, market open and close for the day, and record comments about why you made the trade as well as the lessons learned.
You should also save your trading records so that you can go back and analyze the profit or loss for a particular system, drawdowns (which are amounts lost per trade using a trading system), average time per trade (which is necessary to calculate trade efficiency), and other important factors. Also, compare these factors to a buy-and-hold strategy. Remember, this is a business and you are the accountant. You want your business to be as successful and profitable as possible.
