Yap - Finance API Demo

Yap FloatThis free desktop software application helps traders to analyze and compare stock details effectively. With a Finance API, the app queries various API versions to fetch real-time, historical and analyst stock data. Its cross-platform development ensures seamless performance on Windows, macOS and Linux, leveraging the speed of C++ and the versatility of the Qt Toolkit.

With Yap users can draw a variety of chart types, including CandleStick Charts, Spider Charts, and Histogram Charts for specific timeframes.
Creating charts is as simple as right-clicking on a symbol and selecting the desired chart type, allowing for easy comparison of multiple symbols.
Advanced zoom and pan features enhance interactivity, with basic zoom functions supported by click, drag, and mouse-wheel controls, and the escape key quickly resetting the zoom level. Customizable line charts enable users to change line colors at any time and highlight lines by clicking on the symbol. Different chart background grid types can be selected from the menu.

Advanced features cater to more experienced users, who can add multiple symbols quickly by submitting titles separated by a space character. The application allows for direct comparison of different timeframes to analyze stock performance.

Users can save advanced analysis details to an Excel xlsx file, facilitating the comparison of various details of all entered symbols in beautifully colored, large Excel sheets. Its important to ensure that Microsoft Excel is closed before writing to the same filename; check out LibreOffice Calc. An example exported stock sheet set is available for all major indexes.
For example the application calculates volatility and win probability for each title and time period, making it perfect for comparing the performance of many symbols at once.

The executables are compiled statically for Windows, macOS and Linux, ensuring robust performance across all platforms. Yap supports very big high-resolution fullscreen charts, providing a clear and detailed view of stock data. Some operating systems even benefit from hardware-acceleration. Released under the GNU/GPL License, this app is 100% free and it comes without a warranty!

With its powerful features and user-friendly interface, this desktop software application is an essential tool for traders looking to analyze and compare stock details efficiently.
