JStockCharts - Update - High & Low Prices for predefined Time ranges

JStockCharts has just been improved with a new update to Historical Prices tool, High/Low prices. Using the tool users can search for High/Low prices and their respective traded dates for predefined time periods such as 01 Month, 06 Months, 01 Year and All Time of selected share or of all currently trading shares. Prices are obtained from OHLC data published by CSE. Neither VWAP nor closing prices are used to obtain these extreme price points.

More Updates are coming soon, Including Market Summary on the Main Window and criteria calculation algorithms for new daily 52Week High/Low prices.

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.

JStockCharts update- WatchList & Percentage Price Oscillator Chart

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  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.

Average Cost Calculator - Redefined

Hey there Fellow readers, After an interval I have some time to look into Trading calculators one of these days. Hence fresh improvements in my projects can be expected in coming weeks. First of such improvements goes in to Average Cost calculator, wherein I have made major overhaul in the code. So the changes may not be apparent. But the UI looks good , the code looks good so I feel much better. And I'm pretty confident that It could be made to a more robust application. Major changes was made to JS code to optimize and avoid redundancies. Data structures have been utilized to store contracts so that all the transactions can be viewed using The Trades button, which is a new addition to the previous version. Number of  Trade types have been increased to 4 where Day-Sell and Day-Buy options are included. User can opt to add brokerage to the first contract if the calculated average price is available. This is indeed the case most of the time since the average costs are included in the most portfolio statements. Await for further changes and improvements .Cheers.

Profit_Loss Calculator major UI Update

Profit&Loss calculator has been undergone a rapid update schedule these days and today I modified the structure of the program entirely to facilitate better user experience and versatility. and furthermore on the script I have added Interest calculation feature to cater more accurate cost calculation but of course I made those fields optional so that you may leave them blank. more updates can be anticipated on this week.
                 On this week I added a simple but useful feature. as you know orders aren’t always filled in full quantities for an example if we place a sell order for some 1000 shares this quantity may get executed by parts of 100,500,233,…etc so In such events you don’t need to calculate how many shares have been sold separately. In the sell quantity text fields just enter the quantities separated by ‘+’ operator and the total sold quantity will be calculated on the fly.  (see the image below)

 

Furthermore I have added profit calculation and Quantity calculation features. which facilitates investor and alike to make their trading experiences more fruitful. More updates are coming up. Enjoy folks. Happy trading.

Introducing - Average cost calculator for CSE equity trading

After playing around with my Profit/Loss calculator for few weeks I decided to develop this simple yet useful average cost calculator for equity trading in CSE. The Scenario is quite straightforward , An investor already has X amount of ABC shares at an averaged price of Rs. P1 and he needs to know what will be the average price if he buy Y  amount of ABC shares at Rs. P2. or sell Z ( where Z<=X) amount at Rs P3. 

If you are tangled in the above scenario , then Average price calculator is the solution for you. please note that the Average price calculator works only with Mozilla Firefox and Google Chrome. I'm having an issues getting it work on IE. Please make sure to check out my Profit/Loss calculator as well.

JDownloadManager ►►

JDownload manager is yet a primitive download manager which can be used to download multiple files simultaneously. It only supports HTTP connections hence It is unable to handle FTP/Proxy connections as of now.  Developed entirely using Java/Swing uses Multithreading to download files simultaneously. Downloads can be paused/resumed. browser integration feature is not supported yet hence the user has to add the download link manually.

Download

PS: source can be provided to anyone who is interested in extending this program to a more advanced download manager.

Text Analyser Extended

Program underwent major changes in it's function code , My main goal was to achieve fast analysis but swing event dispatcher thread was lagging behind for like 150 ms for a 30 KB text file. Well that was disappointing , hence the code has now been improvised with Multithreading leaving the event dispatcher thread as it is, all the analysis and saving report procedures are executed in new threads. When I posted this in Javaranch i received some great ideas to improve it .

This post is an extension to my previous posts.

• 2010/04/text-analysis-gui.html
• 2010/04/text-analyser-update.html
• 2010/04/text-analyser-major-update.html

I have done some improvements in the code and GUI and fixed some snags if which I has looked over . I intend to extend this to compare multiple text files because we cannot use java.io.File classes's hashcode method to compare two files because It simply generates the hashcode of the path string of a file. It has no concern on file contents.

Sudoku puzzle solver | Update

Previous release

Eventually I made it more robust against various testing , mostly in input validation , Input validation for a given input is done on the fly using a common KeyEvent Listener, there were alot to consider apart from the basic sudoku rules , for an example in the previous release program didn't check for invalid inputs until user presses the Solve button , this overloaded the amount of work to be done after the it's Action event handler method, 

Another snag was , user enters a number and moves on to another cells to enter numbers , after entering all the values he would return to this particular cell and change the existing value or delete it.  Thus the snag arises that even after the deletion program had made such way that It wouldn't allow that deleted number again to be entered in the current row , column or box set. Eventually these issues were resolved , only a single digit  is allowed to be entered into a cell and of course inputs are checked according to the game rules.
