Every stock trader knows what chart means to stock trading. You can't even set a single foot forward without proper charting tools. Charts allow a stock trader to gauge market depth and market pulse. Before entering into any trade you need to consult charts; before closing the trade you need to check charts.There are two basic types of charts, static and real-time. Static charts are, as the name suggests, do not change over time. So, they are of limited use to any trader. Real-time charts are actually useful. This is because they refresh or update charts with every change in different stock market variables, like, price, volume, trades etc. These charts are often known as self-updating charts.
Inherent benefits of Java have made this language popular for real-time self-updating stock market charts.
