FX charting tool using google app engine.
I want a website i can use to monitor FX price movements for multiple currencies. I want a Java app that takes the high and low of the currency and plots it on a point and figure chart.
A point and figure chart plots the price movement as up or down, without time being considered. Each box can represent 10 pip move in the price, only once it moves 10 basis poitns is the box marked. So for a 10 pip move up the box is marked with an "x" and 10 pip down it's marked with a "o".
The change from and X to O has an additonal critieria. it need to cover 2 boxs (20 pip) reversal before it is marked on the chart. P& F chart example attached.
The data for the price change does not need to be streaming. However, when i refresh the chart it should retrieve live data and update the chart. Obviosly the chart whart will only change if the high or low changes.
