Trade Journal Template Generator

PnL tells you what happened to money. A journal tells you what happened to process. Without written trade context, you cannot tell whether a good result came from a good decision or from a lucky price move that should not be repeated.

That distinction matters in prediction markets because execution quality, resolution review, and sizing discipline often explain performance as much as the thesis itself. A journal is how you keep those factors visible.

Start with the minimum fields required to understand the trade later: market, side, size, price, thesis, and the condition that would invalidate the setup. Then add optional modules only if they support a real review workflow you will follow consistently.

Different strategies need different fields. Arbitrage trades benefit from cross-venue and execution data, while event-driven trades may need catalyst timing and source tracking. The right structure is the one that supports later diagnosis without turning every trade into admin work.

An arbitrage workflow may need both venues, leg prices, target net edge, execution quality, and a post-trade review of whether the opportunity was truly complementary. A simple directional trade may need far fewer fields, but still benefits from explicit probability, invalidation, and lesson tracking.

The point of the generator is to avoid one bloated template for every trade type. A journal that fits the strategy is much more likely to stay complete and useful over time.

The worst mistake is keeping only outcome data. If your journal says who won, how much you made, and nothing about the thesis or fill quality, it cannot teach you much. The second mistake is making the template so demanding that you stop filling it out during active periods.

Another failure is skipping post-trade notes when the result is embarrassing. Those are often the trades with the most process value, which is exactly why the review section should be standardized rather than optional in your mood.
