Fatigue, overtrading and focus during the session
Define overtrading in measurable terms, structure the session into trading windows and breaks, and calculate what unplanned trades cost.
What you will learn
- How to define overtrading with measurable criteria instead of feelings
- How to plan trading windows, breaks and a watchlist size
- How to use a setup score to filter trades during the session
- How to calculate the cost of unplanned trades from your own log
Explanation
Stress, sleep, tilt and general daily routines are covered in the course "Trading Psychology". This lesson deals with the specific problem of a long intraday session: decisions repeat for hours, and attention is limited.
Overtrading, defined
Overtrading means taking trades that your written plan does not allow. Make it measurable with three criteria:
- Off-plan trades: trades that do not match a written setup.
- Count breaches: trades beyond your daily maximum.
- Reactive trades: trades entered within a few minutes after a loss, especially in the same instrument.
Plan adherence rate = planned trades ÷ all trades. Track it daily.
Why extra trades are expensive
A trade without an edge does not have an expectancy of zero; its expectancy is roughly minus the costs (from the previous lesson). Ten random trades at 0.12R cost each lose about 1.2R on average before any bad decisions are counted.
Structure the session
- Trading windows: trade only in the time blocks where your statistics are best, for example the first 90 minutes after the open and, if tested, the last hour. Outside windows, you only manage open positions.
- Scheduled breaks: for example 5 minutes away from the screen every 60 minutes, and a longer break after any loss larger than 1R.
- Watchlist size: limit the instruments you watch actively, for example to 2–4. Switching between many charts ("chart-hopping") reduces the quality of each decision.
- Environment: notifications, chats and social media off during windows.
A setup score
Before each entry, score five yes/no questions: (1) matches a written setup, (2) inside a trading window, (3) spread normal, (4) no release within 15 minutes, (5) stop and target placed before entry. Trade only with 5 of 5. The score takes seconds and interrupts impulsive clicking.
Warning signs of fatigue
Moving a stop further away, increasing size after a loss, entering without a written stop, or feeling irritated by normal price movement. Any one sign is a reason for a break; two signs end the session.
Worked example
Hypothetical example: a trader's log for one day shows 14 trades, 1R = €100, average cost 0.12R per trade (included in the net figures below). Taxes excluded.
- 5 trades scored 5/5: net +2.1R.
- 9 trades were off-plan or reactive: net −2.7R.
- Day result: 2.1R − 2.7R = −0.6R = −€60.
- Plan adherence rate: 5 ÷ 14 = 36%; off-plan share 9 ÷ 14 = 64%.
- Costs of the 9 off-plan trades alone: 9 × 0.12R = 1.08R = €108.
- With a hard cap of 5 trades and the setup score, the day would have ended at +2.1R = +€210, assuming the same 5 planned trades.
One day proves nothing; the point is to repeat the calculation every day and look at the trend over weeks.
Common mistake
Practice activity
On paper, hypothetical data from three days (net R, after costs):
| Day | Planned trades | Planned net R | Off-plan trades | Off-plan net R |
|---|---|---|---|---|
| Mon | 4 | +1.2 | 1 | −0.4 |
| Tue | 3 | −0.8 | 6 | −1.9 |
| Wed | 5 | +0.9 | 2 | +0.3 |
- Calculate the plan adherence rate for each day and for all three days.
- Calculate the total net R of planned and off-plan trades.
- What rule would you add after this review?
Show solution
1. Mon 4 ÷ 5 = 80%; Tue 3 ÷ 9 = 33%; Wed 5 ÷ 7 = 71%. Total: 12 ÷ 21 = 57%.
2. Planned: 1.2 − 0.8 + 0.9 = +1.3R. Off-plan: −0.4 − 1.9 + 0.3 = −2.0R. Total: −0.7R.
3. Tuesday shows most off-plan trades came after planned losses. A sensible rule: after two losing trades, a 30-minute break, and a hard cap of 5 trades per day. Wednesday's positive off-plan result does not justify them; it is a small sample and was not planned.
Limitations: three days are far too few to judge a strategy; this exercise trains the review method.
Key takeaways
- Define overtrading by off-plan trades, count breaches and reactive trades, and track plan adherence.
- Trades without an edge have an expectancy of about minus the costs.
- Trade only in tested windows, take scheduled breaks and watch few instruments.
- Use a quick setup score before every entry and stop on clear fatigue signs.
