The Difference between Trading and Gambling is Documentation
Professional trading desks treat execution as a quantitative business. Without an accurate trading journal, it is impossible to separate good execution from temporary luck, or identify the specific behavioral errors that erode your returns.
The Expectancy Formula:
Expectancy = (Win Rate × Average Win) − (Loss Rate × Average Loss)
A positive expectancy confirms that over a sample of 100 trades, the system generates net profit.

Key Data Fields to Record for Every Trade
- Setup Classification: The specific strategy trigger (e. G., Daily Floor S1 Bounce, 4H Wyckoff Spring).
- R-Multiple: Risk units gained or lost relative to initial stop-loss distance.
- Execution Quality: Did you follow your pre-trade plan exactly, or did you enter/exit prematurely?
- MAE / MFE: The furthest price moved against you (MAE) and in your favor (MFE) while the position was open.
Conducting Weekly Performance Audits
Review all closed positions every weekend. Filter your journal by setup type to identify which strategies generate consistent returns and which are draining capital. Cut underperforming setups and double down on proven edges.
