Automated Trading with R: Quantitative Research and Platform Development - Original PDF
نویسندگان: خلاصه: This book explains the broad topic of automated trading, starting with its mathematics and moving to its computation and execution. Readers will gain a unique insight into the mechanics and computational considerations taken in building a backtester, strategy optimizer, and fully functional trading platform. Automated Trading with R provides automated traders with all the tools they need to trade algorithmically with their existing brokerage, from data management, to strategy optimization, to order execution, using free and publically available data. If your brokerage’s API is supported, the source code is plug-and-play. The platform built in this book can serve as a complete replacement for commercially available platforms used by retail traders and small funds. Software components are strictly decoupled and easily scalable, providing opportunity to substitute any data source, trading algorithm, or brokerage. The book’s three objectives are: To provide a flexible alternative to common strategy automation frameworks, like Tradestation, Metatrader, and CQG, to small funds and retail traders. To offer an understanding the internal mechanisms of an automated trading system. To standardize discussion and notation of real-world strategy optimization problems. What you’ll learn Programming an automated strategy in R gives the trader access to R and its package library for optimizing strategies, generating real-time trading decisions, and minimizing computation time. How to best simulate strategy performance in their specific use case to derive accurate performance estimates. Important machine-learning criteria for statistical validity in the context of time-series. An understanding of critical real-world variables pertaining to portfolio management and performance assessment, including latency, drawdowns, varying trade size, portfolio growth, and penalization of unused capital. Who This Book Is For This book is for traders/practitioners at the retail or small fund level with at least an undergraduate background in finance or computer science. Graduate level finance or data science students.
Enforcing and Trading Patents: Evidence for Europe - Original PDF
نویسندگان: خلاصه: Applying novel datasets, Fabian Gäßler analyzes how key aspects of the current patent system in Europe and Germany, respectively, affect patent enforcement and patent trade. In particular, he shows what factors determine court selection in patent litigation and how the jurisdictional separation of validity and infringement questions favors the patent holder. The author further provides empirical evidence for the market for patents in Europe. The presented findings yield important implications for the ongoing debate on the optimal design of patent systems.
Multi-Period Trading via Convex Optimization - Original PDF
نویسندگان: خلاصه: Our investments will be in a universe of n assets, along with an associated cash account. We let ht ∈ Rn+1 denote the portfolio (or vector of positions or holdings) at the beginning of time period t, where (ht)i is the dollar value of asset i at the beginning of time period t, with (ht)i < 0 meaning a short position in asset i, for i = 1, . . . , n. The portfolio is long-only when the asset holdings are all nonnegative, i.e., (ht)i ≥ 0 for i = 1, . . . , n. The value of (ht)n+1 is the cash balance, with (ht)n+1 < 0 meaning that money is owed (or borrowed). The dollar value for the assets is determined using the reference prices pt ∈ Rn +, defined as the average of the bid and ask prices at the beginning of time period t. When (ht)n+1 = 0, the portfolio is fully invested, meaning that we hold (or owe) zero cash, and all our holdings (long and short) are in assets. Total value, exposure, and leverage. The total value (or net asset value, NAV) vt of the portfolio, in dollars, at time t is vt = 1T ht, where 1 is the vector with all entries one. (This is not quite the amount of cash the portfolio would yield on liquidation, due to transaction costs, discussed below.) Throughout this paper we will assume that vt > 0, i.e., the total portfolio value is positive. The vecto

The brain-shaped mind: what the brain can tell us about the mind - Original PDF
نویسندگان: خلاصه: In the same way atomic structures explain the physical properties of an object, neuroscientists are now learning about the human mind by examining how the neurons in the brain are connected to one another and their surrounding environments. Will brain scientists ever be capable of reading minds? Why are certain things harder to remember than others? The Brain-Shaped Mind addresses these and other questions to provide a clear account of how the structure of the brain influences the workings of the mind. Naomi Goldblum is a lecturer in psychology at Bar-Ilan University in Ramat Gan, Israel. She has studied neuropsychology with a particular emphasis on cognitive psychology.
