Support breaks on gold
Gold 1H, 25–30 Oct. Green support lines held for days, then price closed below them and fell hard. Many breaks don’t follow through like this.
The dashboard
- Resistance line now: where the nearest red line is, and its slope.
- Support line now: where the nearest green line is.
- Last break: which way the last line broke, and when.
- What this means: what price is doing, in plain English.
Golden rules
- A drawing aid, not a signal. It shows no entries, stops or targets.
- Breaks often fail. Price can close through a line and come straight back.
- New lines appear late: a swing is only known a few candles after it.
- Always use a stop loss and risk 1% or less per trade.
🔔 Get told when it fires: click Alerts, choose Auto Trendlines and tick “Price broke above a resistance line” or “below a support line”.
