# Selecting Chart Timeframes

XXYY supports high-frequency charting, allowing you to analyze price action on 1-second, 15-second, and 30-second intervals.

For faster switching, you can customize your view. Click the dropdown menu next to the timeframes to 'favorite' your most-used options. This will pin them to the main selection bar for instant, one-click access.
