GBP/USD, nicknamed "Cable," is one of the oldest and most popular forex pairs. Known for its volatility and strong trends, Cable moves further than EUR/USD on most days and requires careful risk management. This guide covers everything you need to trade GBP/USD effectively.
Why "Cable"?
The nickname dates to the mid-1800s when exchange rates between London and New York were transmitted via transatlantic telegraph cables laid across the ocean floor. The name stuck, and traders still call GBP/USD "Cable" today.

Trend Following
Cable trends strongly:

Around News Releases
Our rule: no new position from 30 minutes before to 30 minutes after a high-impact release (central-bank decisions, NFP, CPI, GDP). Spreads widen and stops slip. If the move is real, it will still be there at minute 31.
- Calendar major UK/US releases
- Assess market expectations
- If you trade the reaction, wait at least 30 minutes after the release
- Use wider stops for volatility
Risk Management for Cable
Wider Stops Required
Cable's volatility demands larger stops:
- Typical EUR/USD stop: 20-30 pips
- Typical GBP/USD stop: 30-50 pips
Adjust position size to maintain consistent risk.
Watch for Spikes
Cable can spike suddenly:
- BOE announcements
- Political headlines
- UK data surprises
No new position from 30 minutes before to 30 minutes after a scheduled high-impact release.
Position Sizing
Higher volatility = smaller positions:
- Size from the stop, not from the pair
- Example: $10,000 × 1% = $100; $100 ÷ (40 pips × $10) = 0.25 lots
- Same dollar risk on every trade, whatever the pair
GBP/USD Correlations
Positive Correlations:
- EUR/USD (both vs USD, though correlation varies)
Negative Correlations:
- USD/CHF (often)
- EUR/GBP (when the pound strengthens, EUR/GBP falls)
- DXY (Dollar Index)
Note: EUR/GBP affects Cable. Watch if EUR/USD and GBP/USD diverge.
Common Cable Trading Mistakes
Using EUR/USD Stops: Cable needs wider stops.
Trading Asian Session: Volume is too low for this pair.
Ignoring UK Politics: Political events move Cable significantly.
Fighting Strong Trends: Cable trends persist—respect them.
Overconfidence After Wins: Volatility can flip quickly.
