Your strategy is only half of your edge
A setup gives you an edge on paper. Whether you actually get it depends on execution: waiting for your trigger, taking the stop you planned, sizing the way you decided. Those are exactly the things that slip when you're tired, stressed, bored or chasing a loss.
That's why most traders don't lose money on bad setups. They lose it on good setups traded badly, or on trades that were never in the plan.
What one real journal shows
The real journal of Strebell's founder holds 368 closed trades between November 2025 and October 2026. A few patterns stand out:
- Trades where the plan was followed averaged +1.72R (+$78). Trades where it wasn't averaged −1.10R (−$51).
- When the feeling at entry was good or excellent, trades averaged +1.75R. When it was bad or very bad, they averaged −0.86R, and none of those 13 trades was a winner.
- Trades without a disturbance averaged +1.65R. Trades taken with doubt about the setup, an emotional trigger, a distraction or fatigue averaged −0.99R.
Read those numbers honestly
These are one trader's results, and some groups are small. A pattern in your data is a reason to pay attention, not proof of cause. But you don't need perfect statistics to act on it: if you lose money every time you enter with a bad feeling, the rule writes itself.
Check in before you look at a chart
Before the open, rate how you slept, your energy, your stress and your focus, and pick one focus for the day. It takes a minute. Then decide your risk mode for the day based on that check-in:
- Normal: rested, calm, clear plan. Trade your full plan.
- Reduced: short night, stress or a busy day. Half size, only A+ setups.
- No trading: exhausted, upset or distracted. Plan, study and review instead.
Know the states that cost you money
Most damage comes from a handful of familiar states. Name them, so you recognise them in the moment:
- FOMO: entering because price is moving, not because your trigger hit
- Revenge: trying to win back a loss straight away
- Overconfidence: sizing up after a winning streak
- Doubt: entering a setup you're not sure about
- Fatigue and distraction: trading while your attention is elsewhere
Rules that protect you from yourself
You can't think your way out of an emotional state while you're in it. Decide in advance, with a calm head, what you'll do:
- A maximum number of trades per day
- A daily loss limit, in R, after which you stop
- Stop after two losses in a row and take a break
- No entry when your feeling at entry is bad or very bad
- No trade without a plan written before the entry
Log the feeling during the trade
How you felt is only accurate in the moment. Hours later the outcome has already rewritten it: a winner feels like a calm, good decision, a loser like bad luck. So write down your feeling at entry and any disturbance while the trade is still open, or straight after.
Review your mindset every week
In your weekly review, look beyond results: on which days did you break rules, how did you sleep before your worst days, which feeling came before your best trades? Choose one adjustment for next week and turn it into a concrete focus goal.
What science says about mindset and trading
From the study
“…subjects whose emotional reaction to monetary gains and losses was more intense on both the positive and negative side … exhibited significantly worse trading performance.”What it means: In 80 day traders followed for five weeks, those who reacted most strongly to wins and losses performed worst. Not just fear: big highs hurt too.

“We conclude that emotions and their regulation play a central role in traders' decision making.”What it means: Interviews with traders at four London investment banks: the better performers managed their emotions before they arose, for example by preparing, rather than suppressing them afterwards.

“We also found that a trader's cortisol rises with both the variance of his trading results and the volatility of the market.”What it means: Stress is physical: on a real trading floor, the stress hormone cortisol rose with volatile results and markets. The authors warn this can shift risk-taking.

“Our results suggest that signals from the body - the gut feelings of financial lore - contribute to success in the markets.”What it means: Traders who sensed their own body better were more profitable and lasted longer in the markets. Noticing how you feel is a skill, not a weakness.

“These results suggest that sleep deprivation poses a dual threat to competent decision making…”What it means: After a night without sleep, people expected more from risky gains and reacted less to losses. A short night is a reason to trade smaller, not bigger.

“…progress monitoring had larger effects on goal attainment when the outcomes were reported or made public, and when the information was physically recorded.”What it means: A meta-analysis of experimental studies: keeping track of your progress helps you reach your goals, and writing it down works better than just thinking about it. That is what a journal is.

“Findings from 94 independent tests showed that implementation intentions had a positive effect of medium-to-large magnitude (d = .65) on goal attainment.”What it means: Deciding in advance 'if X happens, I do Y' clearly increases the chance you follow through. A trade plan with a trigger, stop and 'skip if' conditions is exactly such a plan.
