The best way to measure your trading results is by keeping a trading journal. My personal journaling tool was built for Voodoo Crypto, but there are plenty of free ones if you google it. When looking for a journal or template, make sure to consider journaling both each individual trade as well as each trading session. Break down the numbers for every trade, and reflect on your performance and emotions for each session.
I am not keeping any trading journal and I am very much interested on that. Been planning to download and try it. Since i want to track all my mistakes and my performance in trading.
Also, having a positive mindset in trading is a great help. But you don't have to be overly confident that you have a positive mindset, continue learning what you lack of strategies and styles.
