How to Control Visible Chart History
The zoom and pan feature can be controlled from a computer mouse, hotkey or directly on the chart. Increase or decrease the amount of visible price and indicator history. Easily move back in time and zoom in/out of any period of history available (up to 1500 bars in any time frame).
1. Zoom in/out on the chart using the scroll wheel on your mouse.
