[Moose-dev] Japanese Candlesticks with Roassal

Hi, I just started to get into Roassal (with Pharo 4.0) with the goal to visualize financial data like forex charts. The common visualization is by using japanese candlesticks [1] Because there is not predefined TRShape/ RTShape, I would need to create those shapes on my own. I suspect that this task can't be too complicated but because I'm that very new to Roassal, I'm asking for some hints and maybe code examples. The data needed to visualize one candlestick consists of a few numbers, e.g. 20150501 001300;1.120890;1.120910;1.120890;1.120900;0 (-> downloaded from [2]) First two numbers are Date and Time, the next four Numbers are: open, high, low, close, that last one is the volume and can be omitted. There is a bar to describe the price movement (open/ close) and wicks that describe the highest course and the lowest course during that time frame. The above data describes a One-Minute-Candle. So I'd really appreciate if anyone could give me hints or send me to the right direciction. regards Stefan [1] http://en.wikipedia.org/wiki/Candlestick_chart [2] http://www.histdata.com/
