High
Larger position sizes relative to balance. Suited to experienced traders comfortable with bigger swings in equity.
BFX Trades / Risk Guide
Size every trade on purpose.
Not by feel.
Position sizing is one of the few parts of trading you fully control. This guide gives you a starting lot size (using gold as an example) across three risk tiers and seven account balances — so sizing is settled before you ever open a trade.

01 / Understanding the tiers
High, Mid, or Low.
Match the tier to your balance, experience, and personal tolerance for drawdown — not to what feels exciting.
Mid
A balanced default. Moderate exposure per trade that suits most account sizes and experience levels.
Low
Conservative sizing focused on capital preservation, smaller accounts, or a lower tolerance for drawdown.
02 / The table
Suggested lot sizes.
Figures are a starting point by account balance. Round down to the nearest row if your balance falls between two figures.
| Account balance | High | Mid | Low |
|---|---|---|---|
| £300 | 0.30 | 0.15 | 0.03 |
| £500 | 0.50 | 0.25 | 0.05 |
| £1,000 | 1.00 | 0.50 | 0.10 |
| £1,500 | 1.50 | 0.75 | 0.15 |
| £2,000 | 2.00 | 1.00 | 0.20 |
| £2,500 | 2.50 | 1.25 | 0.25 |
| £5,000 | 5.00 | 2.50 | 0.50 |
Important: Lot sizes are a guide, not a guarantee. They assume a single open position at a time and do not account for your broker's specific margin requirements, spread, or leverage. Trading involves risk of loss. Consider your own circumstances and seek independent advice where appropriate.
03 / A few ground rules
Using the guide well.
Position sizing only works if it's applied consistently — a few habits that keep it useful. Still unsure which tier fits? The risk and lot size FAQ covers the common questions, our groups and pricing explains what each membership includes, and the gold and forex trade ideas overview shows how the tiers are used.
One position at a time
The table assumes a single open trade. Stacking multiple positions changes your real exposure.
Re-check as your balance changes
Your account balance moves. Revisit the table rather than sizing off a figure from last month.
Stay in your tier
Mixing tiers trade-to-trade defeats the purpose. Pick one and stay consistent unless your circumstances change.
Ask if you're unsure
If a figure doesn't make sense for your broker or account type, raise it on your next enquiry call.
