SPX 0DTE trading log
The days I kept the rules and the days I broke them, written down as they happened. This tracks rules, not returns — did I compute R:R before entering, did I respect the time rule, did I stay inside the size limit.

How often
Why one or two a week
The cadence changed in September 2026. Before that I wrote one up on every day I traded, which is why the earlier entries run day after day. It is now usually one or two a week.
Most of my time goes into building the tools. I am building a trading-analysis app with Claude, and that work takes a large part of the day. Writing one entry properly takes half a day of its own. Doing both every day makes both of them thinner.
And committing to daily means filling slots. On a day with nothing worth keeping I would write something anyway, and that entry does not do the job this log exists for. What I am recording is not "I traded today" but "did what I learned today change the next decision."
So I stopped promising a schedule and changed the test instead. An entry goes up when there is something worth keeping. A gap may mean I sat out, or that the day left nothing worth writing down.
What goes into an entry has not changed. Whether I kept the rules, why if I broke them, what share of the daily limit I used — what shrinks is the number of entries, not the density of one.
What gets recorded
- · Strategy — credit spread, iron condor, butterfly, single call/put
- · Gamma regime — positive, negative, or near the flip
- · Rule — kept or broken (and why, if broken)
- · Expiry — 0DTE, weekly, monthly
- · Outcome — target hit, loss contained, loss
Why rules instead of returns
Because a losing day still counts. "I lost but I kept the rule" and "I made money but I broke the rule" — those two are the important ones.
And it doesn't depend on account size. Rule adherence reads the same whether the numbers are large or small.
