GBP/USD

GBP/USD — universally called “Cable” after the transatlantic telegraph cable that originally transmitted the rate — trades approximately 10% of global daily forex volume. Its volatility premium over EUR/USD reflects an additional risk layer: UK-specific political risk (post-Brexit trade adjustments, BoE activism) layered on top of the USD baseline.

For EA traders, GBP/USD’s principal characteristic is range expansion on London open. The pair often consolidates overnight (00-07 UTC) within 20-30 pips, then expands by 60-90 pips in the first three London hours. Trend and breakout EAs that specifically target the London-open expansion outperform 24-hour variants because they avoid the Tokyo session’s false-move tendency.

Session characteristics:

1. Tokyo (00-09 UTC): thin, range-bound, prone to whipsaw. Trend EAs using H1 signals can generate false entries here.
2. London open (07-11 UTC): primary directional window; GBP pairs expand fastest at this time due to BoE-linked flow.
3. NY overlap (12-16 UTC): secondary momentum window; USD data releases drive GBP/USD moves as strongly as EUR/USD.

Spread note: at the brokers in this catalogue, GBP/USD spreads on Standard accounts run 1.2–1.8 pips. Raw/ECN accounts compress to 0.2–0.5 pips with $4–6/lot commission. Scalping strategies require Raw/ECN; swing and trend strategies are viable on Standard.
