I was quite into Goomboo's Journal (https://bitcointalk.org/index.php?topic=60501.0), so i decided to add exponential moving average option for the chart, before the price alert feature.

When you select an exchange, the chart will switch to candlestick chart and a blue "Indicators" button appears. If you click on that button, a popup appears where you can add and delete indicators (only EMA for now).
