The Candlestick.js project on github has some new features already and others are in development.
There are 3 live demos,
- The first is very short, just the minimal code needed to create a nice looking chart.
- The second is a simple explorer with an embeded history of tickers the user looked at.
- The last one includes some data analysis or technical analysis, a search was done to find candles where the close price crossed the simple moving average from below to above. On these events the code to draw a purple line to highlight the event is shown.
There are a lot of small details to work on and improve the Candlestick.js project and I’m working on it as fast as I can.
One major change I hope to accomplish is switch from an object parameter with all the settings to a more general free text language spec where you’ll be able to write something like:
Panels(50,30,30) // define 3 panels with proportional sizes. // the main candlestic panel plus a special moving average // based on the average of the high and low. Panel0( candlestick, sma(20), sma((h+l)/2, 20) ) // 2nd panel with MACD default values of close,12,26,9 Panel1(macd) // of course you can get crazy with customizing // the MACD in panel1 //Panel1( macd( (h+l+c)/3,10,22,6) ) Panel2(volume,sma(volume,50))
I will develop the language in the coming weeks. To use it you will write the code in a string variable or a text file and put it in the main line instead of the options object.
var options = [ 'Panels(50,30,30)', 'Panel0(candlestick,sma(20),sma((h+l)/2,20))', 'Panel1(macd)', 'Panel2(v,sma(v,50)' ].join('\n'); Candlestick(canvasID, data, options);
