Why options traders need one
Poker players review hand histories because memory lies: you remember the big pots, not the dozens of small leaks that actually decide your results. Trading is the same. Options make it worse, because each trade bundles several bets — direction, timing and volatility — into one position.
A journal unbundles them. After a few weeks of honest logging, patterns show up that you can't see trade by trade: maybe your spreads are fine but your long calls into earnings consistently lose to IV crush, or your worst trades cluster in the first 15 minutes after the open.
What to log for every options trade
- Underlying, strategy (long call, put spread, iron condor…), strikes and expiration
- Size, entry and exit prices, and the max loss you planned
- Implied volatility at entry, and whether earnings, CPI or the Fed fell inside the trade (catalyst calendar)
- Why you entered, and why you exited — plan, stop, or emotion
- A one-line note on how you felt. Tilt leaves fingerprints here first.
How to review it
Once a week, group your trades by strategy, by time of day, and by whether an event was inside the trade. Find the bucket with the worst results — that's your biggest leak. Fix one leak at a time; it's worth more than any new indicator.
