This book describes a powerful quantitative finance playground - Gincker Finance, which lets you build advanced financial applications without needing to write a single line of code. With this playground, you can access various free market data APIs, create interactive stock charts, perform technical analysis using various technical indicators, backtest trading strategies, and valuate different asset types using build-in pricing engines. This book and the Gincker Finance playground will be useful tools for quant developers, quant analysts, individual traders, and students of all skill levels. This playground converts different financial software packages and applications into standard templates that expose a simple and common interface. This book uses various walkthrough examples to demonstrate how to create stock charts, perform technical analysis, and backtest trading strategies on this playground by a single mouse click. This playground also allows you to save your work as a unique URL called gincker. This saved gincker not only provides output results, but also brings the development environment directly to users. This means that the gincker can deliver dynamic content: users can use it to regenerate, manipulate, modify, and customize financial analysis to meet their own requirements. The gincker can also be embedded in websites or incorporated into applications. Users can bookmark ginckers for later use or share them with friends, colleagues, and other users.
