Instrument Guide
GBP/USD is one of the most volatile major pairs, making position sizing critical for survival. The 110-pip average daily range means this pair can easily move 1% in a session, so your stops need breathing room but can't be so wide that proper position sizing becomes impossible. The key with Cable is respecting that 110-pip daily range when setting stops. A 30-pip stop is asking to get stopped out by normal market noise, while a 150-pip stop forces your position size so small that profitable trades barely move the needle. Sweet spot is typically 50-80 pips, giving the trade room while keeping position sizes workable. Worked example: On a $50,000 account risking 1% ($500), with a 60-pip stop loss, you'd trade 0.83 lots (60 pips × $10 × 0.83 = $498 risk). Bump risk to 2% ($1,000) and you can trade 1.67 lots with the same stop. The math is straightforward: Risk Amount ÷ (Stop Loss in Pips × $10) = Position Size. For Lux Trading Firm's rules, GBP/USD actually works well. The 6% max drawdown gives you room for multiple losing trades if you stick to 1-2% per trade. The volatility means you can often capture decent R-multiples without holding overnight. The zero daily loss limit is restrictive but manageable if you're disciplined about cutting losers quickly. Just remember that news events can gap this pair 100+ pips, so size accordingly around major announcements like BOE meetings or US data releases.
