Trading is one of the most important aspects of day trading, and a good trading can help you make better decisions when it comes to your investments. A Trading journal is a document that you use to track your trades, losses and profits. It should include all the details about your trades, including the date, time, asset(s) that you are trading and the price at which you bought or sold them. You should also keep track of any changes in market conditions that may have affected your trade – for example, whether the price of the asset has gone up or down since you made your purchase or sale.
