Risk management 101
Position sizing, max risk per trade, drawdown protection. The math that keeps you in the game when a losing streak hits.
Most retail traders blow their account in the first 3 months. Not because their analysis is wrong — because they risk too much per trade and one losing streak wipes them.
This lesson is the boring math that separates breakeven traders from profitable ones. Read it twice.
The 1% rule
Never risk more than 1-2% of your account on a single trade.
That means: if your stop loss hits, you lose 1-2% of total capital. Period. This rule is the difference between surviving a losing streak and gambling.
Why it works mathematically
Imagine you're a 60% win-rate trader (better than most). Even at 60% win rate, statistically you will hit a 5-loss streak roughly once every 100 trades. Here's what 5 consecutive losses do to your account at different risk levels:
| Risk per trade | After 5 losses | Recovery needed |
|---|---|---|
| 1% | -4.9% | +5.2% |
| 2% | -9.6% | +10.6% |
| 5% | -22.6% | +29.3% |
| 10% | -40.9% | +69.3% |
At 1% risk, a 5-loss streak is recoverable with 5-6 normal winning trades. At 10% risk, you need 13+ consecutive wins just to get back to where you started. That math is brutal — and most accounts blow before getting there.
How to calculate position size
For XAUUSD, the formula is:
Example: $5,000 account, 1% risk = $50 risk per trade. Signal entry 2650, SL 2645 → SL distance = $5. Lot size = 50 / (5 × 100) = 0.10 lots.
Play with the calculator below — change the balance, risk %, and SL distance to see how the lot size shifts. Use it on every trade, don't guess.

If price hits SL, you lose $50.00 (1% of account).
Pro risk rule: Never risk more than 1-2% per trade. The math here assumes 1 standard lot = 100 oz gold (most regulated brokers). Verify pip value with your broker if uncertain.
Daily and weekly limits
- Max 3 losses per day.After 3 SL hits in a day, stop trading. Tomorrow is a fresh day; today your edge isn't working.
- Max -5% drawdown per week.If you're down 5% from Monday open by midweek, stop. Review what went wrong before continuing.
- Don't revenge trade. Doubling size to win back a loss is the single fastest way to blow an account. Take the loss. Move on.
Position sizing during news
Around high-impact events (NFP, FOMC, CPI), spreads widen and price gaps. Two options:
- Skip news entirely — close all positions 30 min before release, reopen after spreads normalize. Safest for newer traders.
- Halve position size — if you must hold through news, size at 0.5% risk instead of 1%. Wider SL absorbs spread spikes.
