Gold Pips and Lot Sizes Explained (XAU/USD for UK Traders)

First, the unit: 1 lot = 100 ounces

On MetaTrader 5, XAU/USD is quoted in dollars per ounce, and one standard lot is 100 ounces. That single fact generates everything else: a $1.00 move in the gold price is $100 of profit or loss per 1.00 lot; a $0.10 move is $10; a $0.01 move (one point, the smallest quote increment) is $1.

Most retail trading happens in fractions of a lot: 0.10 lots is 10 oz ($10 per $1 move), and 0.01 lots — the typical broker minimum — is 1 oz ($1 per $1 move).

Pips on gold: the honest answer

In forex, a pip is standardised (0.0001 on most pairs). Gold has no such standard, so communities use 'pip' or 'point' loosely — some mean $0.10 of price movement, some mean $1.00. Neither is wrong; the danger is assuming the other person means what you mean.

The professional habit is to think in dollars, not pips: 'my stop is $5.00 away' is unambiguous; 'my stop is 50 pips away' is a coin flip. Trade Ideas that quote distances in dollars — as the MGT rooms do — remove the ambiguity entirely.

The lot-size formula

Position sizing answers one question: given where my stop is, how many lots can I hold so that hitting the stop costs exactly my risk budget?

• ◆Risk amount = account balance × risk % (the community rule: 1–2%).
• ◆Risk per lot = stop distance in dollars × 100.
• ◆Lot size = risk amount ÷ risk per lot, rounded DOWN to the broker's 0.01 step.

Worked example: a £300 account

Balance $300, risk 1% = $3.00 per trade. Your setup puts the stop $5.00 below entry. Risk per lot = $5.00 × 100 = $500. Lot size = $3.00 ÷ $500 = 0.006 lots — below the 0.01 minimum. The correct response is not to drop the stop: it's to either find a wider, more meaningful stop (say $12.00, giving 0.02 lots) or accept 0.01 lots knowing the effective risk is $5.00 — about 1.7%, still inside the rule.

Why 'round down' matters

Rounding your lot size UP silently increases your risk beyond the plan: 0.02 lots instead of 0.017 doubles a calculated $3 risk into $3.40-plus. Traders who round down trade slightly smaller than the plan allows — which is exactly the habit that survives losing streaks. The calculator floors to the 0.01 step for the same reason.

Sizing is the skill that compounds

Every serious trading community drills the same hierarchy: risk management first, entries second. The MGT education programme teaches position sizing before market structure for exactly this reason — a trader who sizes correctly can be wrong ten times in a row and still have 80% of the account, while a trader who sizes by feel can be right most of the time and still blow up.

Membership includes the beginner desks where every trade idea arrives with its stop defined, so sizing is a calculation rather than a guess — and the monthly education nights walk through the maths live. As ever: CFDs are leveraged, losses can exceed deposits, and past performance never guarantees future results.
