Gann Fan basics:
It’s a set of diagonal lines (angles) drawn from a major swing high or low. They show potential support and resistance based on the relationship between price and time.
The key line is the 1x1 (45° angle) — balanced market.
- Price above 1x1 = bullish strength
- Price below 1x1 = bearish
Other lines: 1x2, 1x4, 1x8 (shallower) and 2x1, 4x1, 8x1 (steeper).
How to draw it on TradingView:
1. Select the Gann Fan tool from the drawing toolbar.
2. Click on a significant swing low (for uptrend) or swing high (for downtrend).
3. Drag to set the 1x1 line at roughly 45° (or let the tool auto-draw the fan).
Tip: Use it together with horizontal support/resistance or moving averages for better confirmation.
Simple but requires practice, test on historical charts first.
