* BEST PERFORMANCE AnyStock JS library can render 250,000 points in less than a second on an average PC. Data stream can append 10,000 data points in 100 milliseconds. You can test how fast AnyStock is, on the performance test page. * MULTIPLE CHART TYPES Line, spline, candlestick, marker, column, open-high-low-close (OHLC), step line, range column, range spline area, and many other chart types are available in Stock Charts. All these series can be used in scroller and in technical indicators. * STOCK DATA ENGINE Especially good for data streaming, data mapping, and transaction-based data flow. Comprehensive set of features for creating real-time data streaming and data manipulation applications. * TECHNICAL INDICATORS Moving Average Convergence / Divergence (MACD), Relative Strength Index (RSI), Simple Moving Average (SMA), Exponential Moving Average (EMA), and Rate of Change (ROC) technical indicators for technical analysis are built in. You can create custom indicators and fully customize both visual and mathematical components. * DATA GROUPING To work with large data sets and represent them successfully on the screen, AnyStock is able to group data points. You can set maximum number of visible points, minimum number of pixels per point, tune data grouping levels, and so on. * STOCK OVERLAY DRAWING TOOLS Complete set of tools for adding various drawings to charts, including Line segment, Ray, Trend Line, Vertical Line, Horizontal Line, Rectangle, Ellipse, Triangle, Trend channel, Andrew's pitchfork, Fibonacci fan, Fibonacci arc, Fibonacci retracement, Fibonacci Time Zones, Buy/Sell Signals, and more – all of them being fully configurable and easily manageable. * NO DEPENDENCY Choose any server platform as AnyChart doesn't need PHP, ASP, or .NET. Visualize data from any warehouse as well as any data warehouse - from files in text, Excel, CSV formats to MySQL, MS SQL, and Oracle database servers. As well as: - cross-platform and cross-browser (IE6+, Chrome, Safari, Firefox, etc.), - easily configurable and highly customizable (JavaSCript API, XML, or JSON), - synchronized plots, - Y-scale comparison mode (changes / percent changes), - show/hide series with legend interactivity, - data point markers for all stock series, - multiple demos in extensive gallery with full source code that can be played with on the Playground, - Scroller UI, pan, zoom, drill down,

•Transparent support of parallel disks. The library provides implementations of basic parallel disk algorithms. STXXL is the only external memory algorithm library supporting parallel disks. •The library is able to handle problems of very large size (tested to up to dozens of terabytes). •Improved utilization of computer resources. STXXL implementations of external memory algorithms and data structures benefit from overlapping of I/O and computation. •Small constant factors in I/O volume. A unique library feature called "pipelining" can save more than half the number of I/Os, by streaming data between algorithmic components, instead of temporarily storing them on disk. A development branch supports asynchronous execution of the algorithmic components, enabling high-level task parallelism. •Shorter development times due to well known STL-compatible interfaces for external memory algorithms and data structures. •STL algorithms can be directly applied to STXXL containers; moreover, the I/O complexity of the algorithms remains optimal in most of the cases. [more info] •For internal computation, parallel algorithms from the MCSTL or the libstdc++ parallel mode are optionally utilized, making the algorithms inherently benefit from multi-core parallelism. •STXXL is free, open source, and available under the Boost Software License 1.0.
