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 and uncheck the box marked ‘Chart Autoscroll’. To reinstate the Autoscroll function, repeat these steps and re-check the box.
