Why Configuration Matters More Than the EA Itself
Two traders using the exact same EA can have completely different results based on their configuration. The right settings protect capital during bad periods and maximize growth during good ones.
The Three Core Settings
1. Lot Size (Position Size)
This determines how much you risk per trade in absolute dollar terms. The calculation:
Recommended starting point:
XAUUSD: 0.01 lot per $100 account balance at 20-pip SL
Example: $1,000 account → 0.10 lot maximum at 1% risk
XAUUSD: 0.01 lot per $100 account balance at 20-pip SL
Example: $1,000 account → 0.10 lot maximum at 1% risk
2. Risk Percent Per Trade
| Account Stage | Risk % | Reasoning |
|---|---|---|
| Building ($300–$1K) | 0.5–1% | Survive learning curve, build confidence |
| Growing ($1K–$10K) | 1% | Standard professional risk level |
| Established ($10K+) | 0.5% | Larger absolute returns, lower % variance |
3. Maximum Drawdown Tolerance
Decide in advance: at what drawdown level will you pause the EA for review?
- Conservative: Pause at 10% drawdown
- Standard: Pause at 15–20% drawdown
- Aggressive: Pause at 25% drawdown
Having this rule prevents the emotional decision of "I'll stop at 50% down" — which is too late.
Practical Setup for $1,000 Account on XAUUSD
- Risk per trade: 1% ($10)
- SL: 20 pips → Lot size: 0.05
- TP: 60 pips (R:R 1:3)
- Max drawdown before pause: 15% ($150)
- Expected monthly: 8–15% at these settings
Do Not Change Settings Mid-Run
Once configured, give the EA at least 50–100 trades before evaluating whether to adjust. Changing settings after 5–10 trades based on short-term results is statistically meaningless and usually harmful.
