For each trade: date and ticker, setup name, the reason for entry in one sentence, entry and stop price, size, the result in risk units, and an honest answer to one question — did I follow the plan or deviate? A screenshot of the chart before entry is worth more than any written description.

After fifty trades, group by setup name and compute expectancy for each separately. Almost always one setup carries all the profit, one is break-even and one loses consistently — and you kept trading it because it's exciting. The fastest improvement in a trader's career is usually deleting the losing setup, not adding a new one.

A second cut: separate trades executed to plan from trades that deviated. If the first group is profitable and the second isn't, your problem is discipline, not analysis — and the fix is entirely different.
