Alpha trader is an excellent blend of all topics surrounding trading. As the author, Brent Donnelly, describes it in the first few lines of this book,
> Every trader is a steaming hot bowl of bias stew and must maintain self-awareness and lucidity behind the screens as the trading day oscillates between boredom and terror.
>
This is the cornerstone idea of the book, and every other concept described is directly or tangentially related to it.
The book’s detour on trading starts on with an excellent and exhaustive deep-dive in behavioural economics. Many of the main biases and flaws concerning human behaviour on decision-making are elegantly introduced and explained, finalising with their respective exemplification in the world of trading - as could not be otherwise. Another interesting concept discussed concerning this topic is the different thinking processes human beings engage with under different situations - which is originally and thoroughly described in *Thinking Fast, Thinking Slow* by Daniel Kahneman, unarguably the father of behavioral economics (with special mention to his lifetime colleague Amos Tversky).
After this walk on the mindset , the author moves onto more technical concepts regarding methodology. Risk management is firstly discussed, expounding the key features to take into account when establishing a risk management framework: risk appetite, free-capital availability and time horizon. Then, he delves into position sizing, emphasising the crucial dynamic behaviour of this concept attending to both exogenous factors (e.g., market conditions, trade risk-reward appeal, dominating narrative) as well as endogenous factors (main one being current performance and the consequent free-capital at disposal) to accurately calibrate the size when entering a position. Again, all these concepts are concretised through insightful real examples Brent himself has been through his career.
Another fundamental concept discussed is market microstructure. The author highlights the importance of being intimately familiar to the structure of the market the operator trades in, including studying the different market participants, how they operate, liquidity of the market and volatility. Mastering all this results essential when developing an edge on the market.
Finally, more contentious topics such as technical analysis and positioning and sentiment are brought into the discussion. The author is extremely cautious when going over them: though he does not demonise them as some practitioners and academics would nowadays - and, in fact, defends the usefulness that remains in such tools -, not only he clearly states their strong points but also makes special emphasis on the shortfalls these techniques entail. The equilibria the author introduces when discussing these topics seems really harmonious to me, since I consider myself an avid supporter of the golden-mean point.
The “Alpha Trader” concept naturally stems throughout the book. A repetitive structure emerges when jumping onto new ideas: once the concept has been introduced and explained, wrong approaches and bad attitudes towards it are presented, moving after on to how an “alpha trader” might deal with these flaws and what the correct behaviour should be.
