The market overview lets you quickly compare price movements on different timescales.
The overview shows three gauges, for the price movement during the last 60 minutes, 24 hours, and 5 days. Each gauge shows the current price in relation to the high-low range (with prices). A gauge which is mostly blue means that the current price is towards the top end of the range; orange means that the price is towards the lower end of the range. The inner bar then shows the open price for the period, and the corresponding % change.
Below the gauges are three simple candle charts, letting you compare short-term market activity on the M5, M15 and H1 timeframes.
