On the back of client feedback our charting team have just delivered a new feature on mobile and desktop. You can now quickly and easily see the percentage movement on any given period for any market. This is accessible from the 'Other Options' drop down, or by right clicking on the chart, and selecting 'Percentage' from the 'Scale' option. The percentage scale will then be reflected on the Y axis for the 1st candle (close) visible on any chart to the last. In other words, the percentage change for the visible candles on the chart.
As you zoom in or out the scale will adjust automatically. You can see an example of this below.
Any questions, please add them to the comments section below.
