JTattoo : Brings a whole new Look and Feel to your J2 applications


Are you fed up with the look and feel of your J2 applications? Well, You are not alone. Originally JDK is shipped with only 03 Look and Feel classes to present UI components in our Java applications (Nimbus,Metal and Motif) or you can use the default system UI by invoking UIManager.getSystemLookAndFeelClassName()).

Which brings us to JTattoo , It is Java library of LookAndFeel classes ,and provides us with 13 different look and feel classes to choose from . Users have different life styles and preferences, While some can get along with simple and lightweight themes , some may prefer darker and flashy UIs. By using JTattoo's wide range of options we can let user decide how he wants our J2 applications to look like according to their tastes.

Here are some sample look and feel classes. you can view all available LF classes here.

                    

                   

How to change LookAndFeel Class?
Following code shows how to assign LF classes dynamically. I have chosen 'smart' LF in JTatoo library.

 public void changeLF() {
        try {
            // select Look and Feel for e:g "Smart" LF
            UIManager.setLookAndFeel("com.jtattoo.plaf.smart.SmartLookAndFeel");
            //initialize this frame's UI Trees with the current look and feel.
            SwingUtilities.updateComponentTreeUI(this);            
        }
        catch (Exception ex) {
            //catches UnsupportedLookAndFeelException & ClassNotFoundException
            ex.printStackTrace();
        }
 } // end 

All available LF classes.
  • com.jtattoo.plaf.aero.AeroLookAndFeel
  • com.jtattoo.plaf.acryl.AcrylLookAndFeel
  • com.jtattoo.plaf.fast.FastLookAndFeel
  • com.jtattoo.plaf.mcwin.McWinLookAndFeel
  • com.jtattoo.plaf.mint.MintLookAndFeel
  • com.jtattoo.plaf.smart.SmartLookAndFeel
  • com.jtattoo.plaf.aluminium.AluminiumLookAndFeel
  • com.jtattoo.plaf.bernstein.BernsteinLookAndFeel
  • com.jtattoo.plaf.graphite.GraphiteLookAndFee
  • com.jtattoo.plaf.hifi.HiFiLookAndFeel
  • com.jtattoo.plaf.noire.NoireLookAndFeel"
  • com.jtattoo.plaf.texture.TextureLookAndFeel"

JStockCharts Update: Combined series chart has been added to Comparable Counters.




Your user friendly charting application has just been updated with a new chart type, It's not an Indicator type but an extremely useful type to render. This chart type is just for the Counter comparison tool and only available therein. Users can select different counters ,select the chart type ( Line(Combined)) for a specific period and press draw button, actually you don't need to select the orientation options for the frame has only one pre configured layout.  
                    Once rendered users are able to view WAP price movements of selected shares for the given period in one plot. Now this is immensely come in handy when you want to compare counters in the same sector , for an example , in the above screenshot I have selected 03 popular banking shares to compare. As always suggestions are welcome to improve this chart type and also make Counter comparison tool more efficient.

JStockChart: Update Notification - Parabolic SAR Indicator


Developed by Welles Wilder, the Parabolic SAR refers to a price-and-time-based trading system. Wilder called this the "Parabolic Time/Price System." SAR stands for "stop and reverse," which is the actual indicator used in the system. SAR trails price as the trend extends over time.The indicator is below prices when prices are rising and above prices when prices are falling. In this regard, the indicator stops and reverses when the price trend reverses and breaks above or below the indicator.

JStockCharts Update : Stock Charts Comparison Tool & Mass Index Indicator


Stock Charts Comparison Tool


Comparison Tool  rendered on a 19" widescreen monitor
Stocks (Counters) Comparison tool is the latest addition to JStockCharts and of which I'm really proud of presenting to my users. The knowledge/experience I gained coding this tool is enormous and Even I'm genuinely thrilled to write this blogpost about it.
             Essentially , using this tool users can select up to 06 shares , select a specific chart type/indicator , select a specific period and draw charts for them separately as depicted in the screenshot, this shall be usefull when it comes to observe sector wise trends and I intend to improvise this tool more by letting users to save selections in persistent state so that they can be observed time to time, as is the case of ever changing stock market.
               Actually there is no theoretical limitation to the number of shares that can be compared, but I have put up this limitation of 06 counters to render charts more clearly on single monitor systems, I'm afraid most people use notebook computers hence even 06 charts wouldn't be clearly analyzable. Feel free to try this an new ideas and suggestions are always welcome and would be highly appreciated.

New Indicator : Mass Index



Developed by Donald Dorsey, the Mass Index uses the high-low range to identify trend reversals based on range expansions. In this sense, the Mass Index is a volatility indicator that does not have a directional bias. Instead, the Mass Index identifies range bulges that can foreshadow a reversal of the current trend.

JStockCharts Update- Ease of Movement Indicator


Ease of Movement Indicator (EMV)


Developed by Richard Arms, Ease of Movement (EMV) is a volume-based oscillator that fluctuates above and below the zero line. As its name implies, it is designed to measure the "ease" of price movement. Arms created Equivolume charts to visually display price ranges and volume. Ease of Movement takes Equivolume to the next level by quantifying the price/volume relationship and showing the results as an oscillator. In general, prices are advancing with relative ease when the oscillator is in positive territory. Conversely, prices are declining with relative ease when the oscillator is in negative territory.



JStockCharts provides 14 day SMA of EMV. Users must select a period higher than or equal to 03 month to render this chart type.

Further I have optimized the code of WatchList to ensure more effectiveness of the data displayed in it. for an example I have added a no change color (orange) for two types of changes in closing price. first , If there were no trades for the last trading day or previous trading date for a given counter, there is no point of calculating the change hence such counters rendered in no change color. and second is the most obvious , of which closing prices were same for the two days. 
In the following screen capture HSIG's closing price shows as 0.00 because it hasn't been traded for the last updated trading date. other three counter's are self explanatory.

JStockCharts update- Aroon Indicator & StochRSI Charts


Aroon Indicator
Developed by Tushar Chande in 1995, Aroon is an indicator system that determines whether a stock is trending or not and how strong the trend is. "Aroon" means "Dawn's Early Light" in Sanskrit. Chande chose this name because the indicators are designed to reveal the beginning of a new trend. The Aroon indicators measure the number of periods since price recorded an x-day high or low.


StochRSI
Developed by Tushard Chande and Stanley Kroll, StochRSI is an oscillator that measures the level of RSI relative to its high-low range over a set time period. StochRSI applies the Stochastics formula to RSI values, instead of price values. This makes it an indicator of an indicator. The result is an oscillator that fluctuates between 0 and 1.

If you are new to JStockCharts please refer to this post.

I have been working on a way to enable users to save his favorite/holding shares and daily monitor their trading summary through a single window. The Latest feature of the JStockCharts , WatchList enables users to accomplish this task. It simply provides a window to add/remove your desired shares to the table on the right side, once you updated the latest price list to the application you can go ahead and analyze the trading summary of the shares in your watchList easily by clicking the ico_alpha_ClipboardEdit_24x24 icon in the toolbar or by going through Tools menu.

Technical Indicator – PPO ( Percentage Price Oscillator)
The Percentage Price Oscillator (PPO) is a momentum oscillator that measures the difference between two moving averages as a percentage of the larger moving average. As with its cousin, MACD, the Percentage Price Oscillator is shown with a signal line, a histogram and a centerline. Signals are generated with signal line crossovers, centerline crossovers and divergences. Because these signals are no different than those associated with MACD, this article will focus on a few differences between the two. First, PPO readings are not subject to the price level of the security. Second, PPO readings for different securities can be compared, even when there are large differences in the price.
Reference : StockCharts.com
This useful indicator charts are available for over 03 Months periods.
