The Complete Trading Journal Guide

A trading journal is a record of every trade you take, including why you took it, not just whether it won or lost. Without that context, you cannot tell the difference between a good decision that happened to lose and a lucky guess that happened to win.

At minimum, track the symbol, entry and exit price, position size, the setup or reason for the trade, and your emotional state at the time. Over dozens of trades, patterns emerge that are invisible trade by trade: maybe you consistently lose on trades taken outside your plan, or your win rate drops sharply after a loss.

Reviewing the journal matters as much as keeping it. Set a weekly habit of reading back through recent trades and asking what you would do differently, rather than letting entries pile up unread. The journal is only useful if it changes your next decision.

The Tradeskill’s built-in trade journal logs every simulated trade automatically, with tags, notes, and an AI trade review on each closed position, so the habit is already built into the free paper trading simulator instead of a separate spreadsheet you have to maintain yourself.
