Andrew Aziz and performance psychologist Crede Sheehy-Kelly's 2025 system for building a complete trading system: strategy is a concept, a TradeBook is the manual — selection, identification, execution, review — and the edge is never one piece but the combination.
Technology, strategy, and psychology each fail alone; the TradeBook is the overlap where all three meet, and that overlap is the only durable edge.
The edge in trading doesn’t come from any one of these pieces on their own. It comes from combining them into a system that works for you. That’s what a TradeBook helps you build—a personalized, complete, and practical trading guide based on your tools, your mindset, and your strategy.
Why it matters
Technology, strategy, and psychology each fail alone; the TradeBook is the overlap where all three meet, and that overlap is the only durable edge.
Use when: When a trader keeps buying better tools instead of building a system.
A one-line case for routine as infrastructure: concentrated volatility at defined hours lets a retail trader be sharp; 24/7 markets invite 24/7 bleed.
The consistency of your trading hours has a direct impact on the consistency of your results.
Why it matters
A one-line case for routine as infrastructure: concentrated volatility at defined hours lets a retail trader be sharp; 24/7 markets invite 24/7 bleed.
Use when: When your trading day has no edges and neither do your results.
The TradeBook's gatekeeping function: it converts 'this looks good' into a binary fit-or-skip decision, which is where most retail losses begin.
If you cannot put the trade opportunity into any of your TradeBooks, it means you should not take that trade. And this is the most important purpose of your TradeBooks. They help you answer the question: Should I take the trade or not?
Why it matters
The TradeBook's gatekeeping function: it converts 'this looks good' into a binary fit-or-skip decision, which is where most retail losses begin.
Use when: When a tempting setup does not quite fit your plan but you want it anyway.
0.5% a day compounded grows an account nearly 20-fold in three years — the math case for boring consistency over spectacular trades.
This calculation demonstrates why protecting your capital and maintaining consistent, small gains are key to long-term success. It is not about hitting home runs; it is about playing the long game.
Why it matters
0.5% a day compounded grows an account nearly 20-fold in three years — the math case for boring consistency over spectacular trades.
Use when: When impatience pushes you toward the big swing instead of the small edge.
The counterintuitive core of the psychology chapter: over-focusing on the money is what produces the rule-breaking that loses the money — measure the process instead.
Prioritize the successful execution of your TradeBooks above your PNL.
Why it matters
The counterintuitive core of the psychology chapter: over-focusing on the money is what produces the rule-breaking that loses the money — measure the process instead.
Use when: When a green day of sloppy trading feels like success, or a disciplined red day feels like failure.
Most price action is choppy with no clear winner; the discipline to wait for a readable signal is priced like an entry skill.
Recognizing when not to trade is as valuable as knowing when to take a position.
Why it matters
Most price action is choppy with no clear winner; the discipline to wait for a readable signal is priced like an entry skill.
Use when: When you feel the pull to trade an ambiguous tape.
The technology chapter's warning: the tools were built to increase broker income, and they work — by making you trade more and win less.
A November 2024 study shed light on this trend, analyzing 142 gamification features in the mobile trading apps of 17 major U.S. brokers. The research found that while these features successfully increased retail trading activity and income for brokers and market makers, they often led to lower returns and higher volatility for the retail traders themselves.
Why it matters
The technology chapter's warning: the tools were built to increase broker income, and they work — by making you trade more and win less.
Use when: When a flashy app makes trading feel like a game and you trade more than planned.
Seven years of ORB research: stopped out 75% of the time, profitable on 25%, and still beating the market — expectancy, not win rate, is the scoreboard.
This highlights a vital aspect of trading: success is not about being right most of the time. Instead, it is about ensuring that your winning trades are large enough to outweigh your losses.
Why it matters
Seven years of ORB research: stopped out 75% of the time, profitable on 25%, and still beating the market — expectancy, not win rate, is the scoreboard.
Use when: When a low win rate tempts you to abandon a working system.
Losses compound against you, which is why the stop loss is the foundation of the whole system: capital protection is the edge beneath the edge.
A 50% loss means you will need to double your account (100%) just to get back to even.
Why it matters
Losses compound against you, which is why the stop loss is the foundation of the whole system: capital protection is the edge beneath the edge.
Use when: When sizing up a trade, run the recovery math first.
The book's spine sentence: a strategy only says what to look for, a TradeBook scripts selection, identification, planning, entries, exits, stops, position sizing, management, and psychology.
There is a fundamental difference between a strategy and a TradeBook. A strategy outlines the overall concept—what to look for in a particular type of trade and how that trade generally works. A TradeBook, however, is much more practical, more like a manual.
Why it matters
The book's spine sentence: a strategy only says what to look for, a TradeBook scripts selection, identification, planning, entries, exits, stops, position sizing, management, and psychology.
Use when: When someone pitches a 'strategy' with no rules for entries, exits, or review.
The formal definition: an edge is not a feeling about a setup, it is an opportunity written down, repeatedly recognizable, and positive-expectancy — the casino model of trading.
Bear Bull Traders calls your edge in the markets your “TradeBooks”, and we define your edge as a specific market opportunity codified in a specific TradeBook, which is repeatedly identifiable, and provides you with a positive expected value in profit, over time, when executed with discipline.
Why it matters
The formal definition: an edge is not a feeling about a setup, it is an opportunity written down, repeatedly recognizable, and positive-expectancy — the casino model of trading.
Use when: When asked to name your edge and you can only describe vibes.
Sheehy-Kelly de-fogs trading psychology: it is not vibes or affirmations, it is the measurable ability to execute the book you wrote — the mental edge.
So, from here on in, when I talk about trading psychology, I am talking about the mindset and emotional control that enables you to execute your TradeBooks, exactly as intended, every time you trade.
Why it matters
Sheehy-Kelly de-fogs trading psychology: it is not vibes or affirmations, it is the measurable ability to execute the book you wrote — the mental edge.
Use when: When psychology talk drifts into mysticism instead of execution discipline.
