We often think of finance as a glamorous world, a place where investment bankers amass huge profits in gleaming downtown skyscrapers. There's another side to finance, though - the millions of amateurs who log on to their computers every day to make their own trades. The shocking truth, however, is that less than 2% of these amateur traders make a consistent profit. Why, then, do they do it? In Noise, Alex Preda explores the world of the people who trade even when by all measures they would be better off not trading. Based on firsthand observations, interviews with traders and brokers, and on international direct trading experience, Preda's fascinating ethnography investigates how ordinary people take up financial trading, how they form communities of their own behind their computer screens, and how electronic finance encourages them to trade more and more frequently. Along the way, Preda finds the answer to the paradox of amateur trading - the traders aren't so much seeking monetary rewards in the financial markets, rather the trading itself helps them to fulfill their own personal goals and aspirations. -- ǂc Provided by publisher.

Explore Automated Market Makers (AMMs), the underlying protocols used by decentralized exchanges (DEX) to allow users to perform trades of cryptocurrencies in a decentralized way with no middlemen. This book provides a thorough study and a clear-cut exposition of the principal AMMs (Uniswap v2 and v3, Balancer, and Curve). You'll receive a detailed description of how these AMMs work, unveiling the mathematics behind them and showing plenty of examples as well as novel proofs for several interesting facts. Each chapter describes an AMM's core idea and derives the mathematical formulas used in the code, giving careful explanations of the logical thinking involved and detailing the steps needed to reach those formulas. All these explanations are complemented with thoughtfully chosen examples which further help to enlighten the readers on how the formulae work. In addition, the relevant parts of the codes of the AMMs are shown after explaining each formula so that the actual implementation of the formulae can be seen. In a traditional trading market a buy order has to be matched with a sell order to achieve a trade. However, for an AMM, users trade against the protocol itself, a smart contract, or a community pool of funds. In simple terms this is an open source computer program in which mathematical formulas define prices. Automated Market Makers examines this critical point revealing that no banks or intermediaries are necessary, giving crucial financial access to a much larger crowd, regardless of who they are with less barriers to access. You will: Understand the principals of decentralized finance (DeFi) Grasp mathematical formulae that underpin decentralized exchanges Work with Solidity programming language Review current industry best practices .
