Why Keep a Journal of Your Trading and a Free Template

Too often we hear from struggling traders who ask what they can do to improve their trading. The questions I always ask in response are, “Did you follow your trading plan?” and “What trades are, or aren’t, working for you?”. We discuss trading plans in a separate blog post, but a trade journal is a separate and equally necessary tool in your trading arsenal.

What is a trading journal? A trading journal is a tool used to track every one of your trades. Using a journal is essential to improving your trading and simply knowing what works, and what doesn’t work, for you. This applies to your overall strategy, the individual stocks traded, and even the time of the day. The key is being able to see exactly where you made or lost money.

If you were a baseball coach and you knew one of your players batted .350 against left handed pitchers and another batted .190, you’d know exactly which player to start if you were facing a lefty. The same applies to trading. If you have stats from a trading journal to know what works or doesn’t work, you’re far more likely to repeat winning trades or strategies. Without careful records there’s no way to know if your strategy is working or not, let alone having the ability to refine it.

Your journal can be as simple or as complicated as you’d like. There are obvious columns like the security, price purchased and sold, date purchased and sold, and your profit on the trade. Other columns are up to you. I would consider a column for the time of the day, stock sector and a notes section for anything worth remembering about that particular trade. Your note might be something unusual about the sector, the time of day or what happened after you exited the trade. The key is to put it down in the journal so that you can learn from your success or failures.

Taking it down to the basics, here is a link to one of the best P/L spreadsheets I’ve seen. It also has a link to download it if you’d like. I’m attaching it here with permission from Twitter user @inefficientmrkt https://inefficientmarket.tumblr.com/PandLspreadsheet
