Why the starting balance matters
The base lot is 0.01 for every 5,000 units of balance, and never below the broker minimum of 0.01. So below 10,000 units the EA cannot trade smaller than 0.01: a 2,000 balance trades 2.5 times bigger, relative to its size, than a 10,000 balance does. Bigger balances scale the lot up in steps and keep the risk in proportion.
| Balance | Base lot | Worth |
|---|---|---|
| Under 10,000 | 0.01 (the broker minimum) | $0 to $100 cent · up to $10,000 standard |
| 10,000 | 0.02 | $100 cent · $10,000 standard |
| 25,000 | 0.05 | $250 cent · $25,000 standard |
| 50,000 | 0.10 | $500 cent · $50,000 standard |
| 100,000 | 0.20 | $1,000 cent · $100,000 standard |
