jStock

jStock is a tool for technical analysis of stocks. It draws logarithmic charts (candlesticks) based on daily open, high, low, and close for a stock. Both daily and weekly charts are supported, as is volume and a few technical indicators. Data files can be fetched from the Internet and from downloaded files. Notes and user-drawn lines are stored in an (optional) database. Important design parameters have been to maximise the area for the candlestick chart and minimise the user interactions for daily use.

    Release Notes: Most changes are due to an internal redesign. There are also changes in the keyboard user interface, database schema, and the Indicators interface classes. User-drawn lines are now supported for indicators. It's possible to view lines and highlighted candlesticks at the same time, and if database support is enabled, it is possible to have an individual set of indicators per ticker.

        Release Notes: Several bugs in the generic file reader are fixed. A new exchange field was added to the user interface so that it is a lot easier draw charts for stocks from different exchanges. As this this field isn't likely to be updated often it doesn't request focus, so that it has to be clicked in order to write into it.

          Release Notes: This is a bugfix and cleanup release only. Most fixes are minor, but there is a more serious one fixing a problem with changing parameters for RSI and MACD indicators from the application.

            Release Notes: A MACD indicator was added. If a day is selected the indicators in separate panels now print out values for the selected day. The focus for keyboard input now follows the mouse cursor. This may be removed or become a config option if it is too annoying. Indicators in the candlestick panel are now correctly drawn if the window is resized.
