++Testing and Tuning Market Trading Systems: Algorithms in C - Original PDF
نویسندگان: خلاصه: Build, test, and tune financial, insurance or other market trading systems using C++ algorithms and statistics. You’ve had an idea and have done some preliminary experiments, and it looks promising. Where do you go from here? Well, this book discusses and dissects this case study approach. Seemingly good backtest performance isn't enough to justify trading real money. You need to perform rigorous statistical tests of the system's validity. Then, if basic tests confirm the quality of your idea, you need to tune your system, not just for best performance, but also for robust behavior in the face of inevitable market changes. Next, you need to quantify its expected future behavior, assessing how bad its real-life performance might actually be, and whether you can live with that. Finally, you need to find its theoretical performance limits so you know if its actual trades conform to this theoretical expectation, enabling you to dump the system if it does not live up to expectations. This book does not contain any sure-fire, guaranteed-riches trading systems. Those are a dime a dozen... But if you have a trading system, this book will provide you with a set of tools that will help you evaluate the potential value of your system, tweak it to improve its profitability, and monitor its on-going performance to detect deterioration before it fails catastrophically. Any serious market trader would do well to employ the methods described in this book. What You Will Learn • See how the 'spaghetti-on-the-wall' approach to trading system development can be done legitimately • Detect overfitting early in development • Estimate the probability that your system's backtest results could have been due to just good luck • Regularize a predictive model so it automatically selects an optimal subset of indicator candidates • Rapidly find the global optimum for any type of parameterized trading system • Assess the ruggedness of your trading system against market changes • Enhance the stationarity and information content of your proprietary indicators • Nest one layer of walkforward analysis inside another layer to account for selection bias in complex trading systems • Compute a lower bound on your system's mean future performance • Bound expected periodic returns to detect on-going system deterioration before it becomes severe • Estimate the probability of catastrophic drawdown Who This Book Is For Experienced C++ programmers, developers, and software engineers. Prior experience with rigorous statistical procedures to evaluate and maximize the quality of systems is recommended as well.
Concise course in algebraic topology - Original PDF
نویسندگان: خلاصه: Algebraic topology is a basic part of modern mathematics, and some knowledge of this area is indispensable for any advanced work relating to geometry, including topology itself, differential geometry, algebraic geometry, and Lie groups. This book provides a detailed treatment of algebraic topology both for teachers of the subject and for advanced graduate students in mathematics either specializing in this area or continuing on to other fields. J. Peter May's approach reflects the enormous internal developments within algebraic topology over the past several decades, most of which are largely unknown to mathematicians in other fields. But he also retains the classical presentations of various topics where appropriate. Most chapters end with problems that further explore and refine the concepts presented. The final four chapters provide sketches of substantial areas of algebraic topology that are normally omitted from introductory texts, and the book concludes with a list of suggested readings for those interested in delving further into the field.
Vitamin E: Chemistry and Nutritional Benefits - Original PDF
نویسندگان: خلاصه: Vitamin E is a plant-derived, lipid-soluble substance whose molecular struc- ture is comprised of a chromanol ring with a side chain located at the C2 position. Vitamin E refers to a group of eight different compounds: α-, β-, γ-, and δ-tocopherols and the corresponding four tocotrienols. The four tocopherols have a saturated phytyl side chain, while tocotrienols have an unsaturated isoprenyl side chain containing three double bonds at C3′, C7′, and C11′. The double bonds of tocotrienols' side chains at C3′ and C7′ have a trans-configuration. The α-, β-, γ-, and δ-forms differ with respect to the number and position of methyl groups on the chromanol ring. The α-forms of tocopherol and tocotrienol have three methyl groups at the C5, C7, and C8-positions of the chromanol ring, while the β- and γ-forms have two and the δ-forms have one methyl group as illustrated in Figure 1.1.
India and the Silk Roads: The History of a Trading World - Original PDF
نویسندگان: خلاصه: India and the Silk Roads is a global history of a continental interior, the first to comprehensively examine the textual and material traces of India’s caravan trade with central Asia. But what was the fate of these overland connections in the ages of sail and steam? This book brings the world of caravan trade to life—a world of merchants, mercenaries, pastoralists and pilgrims, but also of kings, bureaucrats and their subjects in the countryside and towns. Their livelihoods did not become obsolete with the advent of ‘modern’ technologies and the consequent emergence of new global networks. Terrestrial routes remained critically important, not only handling flows of goods and money, but also fostering networks of trade in credit, secret intelligence and fighting power. With the waning of the Mughal Empire during the eighteenth century, new Indian kingdoms and their rulers came to the fore, drawing their power and prosperity from resources brought by caravan trade. The encroachment of British and Russian imperialism into this commercial arena in the nineteenth century gave new significance to some people and flows, while steadily undermining others. By showing how no single ruler could control the nebulous yet durable networks of this trading world, which had its own internal dynamics even as it evolved in step with global transformations, this book forces us to rethink the history of globalisation and re-evaluate our fixation with empires and states as the building blocks of historical analysis.

Family Therapy: A Constructive Framework - Original PDF
نویسندگان: خلاصه: This book brings together two areas of psychotherapy that should converge neatly – but usually do not. The first is the practice of constructive thera- pies, my umbrella term for the brief, collaborative and competency-based approaches that are increasingly popular among helping professionals. For many, including myself, the appeal of these approaches lies partly in their refreshingly positive, optimistic and frankly challenging philosophy, and partly in the possibilities they offer for brief but effective work. The best known and most influential models within this general orientation are probably solution-focused therapy and narrative therapy. The second area is the practice of family therapy, involving the fascinating dilemmas of working with relationships. For many helping professionals in the fields of counselling, social work, psychology, education and health, family- based work is a major occupation and challenge. Many practitioners have an interest in constructive therapies. Many practitioners have an interest in working with families. This book is written for those who have an interest in bot
Feminist New Materialisms, Sport and Fitness: A Lively Entanglement - Original PDF
نویسندگان: خلاصه: This book offers the first critical examination of the contributions of feminist new materialist thought to the study of sport, fitness, and physical culture. Bringing feminist new materialist theory into a lively dialogue with sport studies, it highlights the possibilities and challenges of engaging with posthumanist and new materialist theories. With empirical examples and pedagogical offerings woven throughout, the book makes complex new materialist concepts and theories highly accessible. It vividly illustrates sporting matter as lively, vital, and agentic. Engaging specifically with the methodological, theoretical, ethical and political challenges of feminist new materialisms, it elaborates understandings of moving bodies and their entanglements with human, non-human, technological, biological, cultural, and environmental forces in contemporary society. This book extends humanist, representationalist, and discursive approaches that have characterized the landscape of critical research on active bodies, and invites new imaginings and articulations for sport and moving bodies in uncertain times and unknown futures.آیا کتاب مورد نظر هنوز بر روی سایت قرار نگرفته است؟ جای نگرانی نیست! کافی است بر روی گزینه سفارش کتاب کلیک کرده و درخواست خود را ثبت کنید. در کمتر از چند ساعت کتاب شما را آماده خواهیم کرد.
