How do I scroll back on a chart to view historical prices?

MT4 has a default setting called Autoscroll which is designed to ensure the latest price is displayed. To disable this function so you can scroll through historical pricing, right-click on a chart and select the ‘Properties’ option. Next, click on the ‘Common’ tab, uncheck the box marked ‘Chart Autoscroll’, and then click ‘OK’.

To reinstate the Autoscroll function, repeat these steps and re-check the box.
