The price scale on the right of the Studio chart fits itself to the candles in view. The A button at its bottom shows that: highlighted means auto-fit is on.
Setting it by hand
- Drag the price scale up or down to stretch or squeeze it. Auto-fit turns off and the A button dims.
- Click A, or double-click the price scale, to fit it to the candles again.
- Opening a different symbol or timeframe always starts auto-fit again.
A chart that looked empty after switching symbols
Until 8 October 2026, a scale you had set by hand stayed in place when you opened another symbol. Going from a $1,000 stock to a $200 one drew the new candles far below the window, so the chart looked empty until you pressed A. A new symbol now fits its own prices straight away, on the desktop and the phone.
