Pip Value & Contract Specifications
GBP/USD carries a standard contract size of 100,000 GBP per lot. One pip equals 0.0001 — the fourth decimal place. Since GBP/USD is quoted in USD, the pip value in USD mirrors EUR/USD exactly: $10.00 per standard lot. To convert this to INR, multiply by the prevailing USD/INR rate: at 83.50, that works out to ₹835.00 per pip per standard lot.
Although the USD pip value is identical to EUR/USD, Cable's characteristically wider daily swings mean your stop losses typically need more breathing room — so effective rupee risk per trade climbs quickly even at modest lot sizes. Always calculate before you commit.
| Lot Size | Contract (GBP) | Pip value (USD) | Pip value (INR @ 83.50) | 30-pip stop | 100-pip stop |
|---|---|---|---|---|---|
| 0.01 (micro) | 1,000 | $0.10 | ₹8.35 | ~₹250.50 | ~₹835 |
| 0.10 (mini) | 10,000 | $1.00 | ₹83.50 | ~₹2,505 | ~₹8,350 |
| 0.50 | 50,000 | $5.00 | ₹417.50 | ~₹12,525 | ~₹41,750 |
| 1.00 (standard) | 100,000 | $10.00 | ₹835.00 | ~₹25,050 | ~₹83,500 |

Position Sizing Example
Suppose you have a ₹2,00,000 account and risk 1% per trade (₹2,000). You decide on a 50-pip stop loss on GBP/USD — a reasonable buffer for a 4-hour chart setup, though Cable can cover 50 pips in under 30 minutes during a UK data release.
At USD/INR 83.50, each pip per standard lot = ₹835. The formula:
Lots = Risk ÷ (Stop pips × Pip value in INR)
Lots = ₹2,000 ÷ (50 × ₹835) = ₹2,000 ÷ ₹41,750 ≈ 0.047 lots
Round down to 0.04 lots to stay safely within your risk limit. On a high-impact event day — such as a Bank of England rate decision or UK inflation print — where a 150-pip stop is more appropriate: ₹2,000 ÷ (150 × ₹835) ≈ 0.015 lots. The high rupee pip value on Cable means even small lot sizes represent meaningful exposure — the calculator above is your first line of defence every time you trade.
About GBP/USD — Key Drivers & Trading Hours
GBP/USD earns its nickname "Cable" from the undersea telegraph cable laid across the Atlantic in the 1800s, which first carried exchange rate data between London and New York. Today it ranks among the most actively traded currency pairs in the world and consistently posts the largest daily pip ranges of the major pairs — averaging 150–200 pips per day, well above the 80–120 pips typical of EUR/USD. This makes Cable attractive for trend followers and breakout traders, but it demands wider stop losses and more disciplined position sizing in return.
Primary drivers of GBP/USD include: Bank of England (BoE) monetary policy announcements (released every six weeks), UK CPI inflation data (monthly), UK employment figures and GDP readings, US Federal Reserve policy decisions (which move the USD side of the pair), and ongoing UK political developments including trade negotiations and fiscal policy shifts. Sterling is one of the most sentiment-sensitive major currencies — unexpected political events or government policy surprises can generate 200–300 pip moves within a matter of hours without warning.
Best trading hours for Indian traders (IST, UTC+5:30): GBP/USD is most active during the London session (13:30–21:30 IST). Early UK data releases arrive around 12:00–13:30 IST and can produce sharp spikes before full London liquidity builds — exercise caution if trading around those releases. The London–New York overlap (18:00–21:30 IST) offers peak liquidity, tightest spreads, and the strongest trending conditions. Cable is comparatively subdued during the Asian session, though breakouts at the London open can be swift and significant if sentiment has shifted overnight.
