NAS100 lot size calculator.
The Nasdaq 100 contract is not the same at every broker. Enter the balance, the risk, the stop in points and your contract size; get the lots, the units and the money at risk.
$10,000 account, 1% risk ($100), 50-point stop on NAS100 with 1 unit per point ($1/point): 2.00 lots. If your broker uses 0.1 units per lot ($0.10/point), it is 20.00 lots.
Advanced: contract size, digits, lot step
{"action":"buy","symbol":"EURUSD","sl":20}
The sl is in pips the way the SignalForge EA counts them (SL/TP mode Pips, the default). With position size type Risk % in your dashboard and no lot in the alert, the EA sizes the order itself from your live balance. Use your broker's exact symbol name if it has a suffix.
Formula: lots = money at risk / (contract size × stop distance in price, converted to the account currency). Rounded down to your lot step. Exchange rates: ECB reference rates, refreshed daily, served from our own API; if it cannot be reached the calculator uses a built-in table and says so.
How NAS100 lot size is calculated
The Nasdaq 100 contract is not the same at every broker. Four steps:
- Money at risk = balance × risk %. $10,000 at 1% = $100.
- Stop in price = 50 index points (enter it as a price distance).
- Loss per 1.00 lot = contract × stop. With 1 unit per point: 1 × 50 = $50.
- Lots = $100 / $50 = 2.00 lots, rounded down to 0.01.
Contract size: 1 vs 0.1 vs $1 per point
Many MT5 brokers use 1 index unit per lot, so 1.00 point is $1 per lot. Others use 0.1 units, where 1.00 point is $0.10 per lot and the same risk needs 10 times the lots. Check Specification and put the real contract in Advanced; a calculator with the wrong contract is worse than no calculator.

|---|---|---|---|---|
| $10,000 | 1% = $100 | 50 points | $50 | 2.00 |
| $10,000 | 1% = $100 | 100 points | $100 | 1.00 |
| $50,000 | 0.5% = $250 | 50 points | $50 | 5.00 |
| $10,000 | 1% = $100 | 50 points | $5 (0.1 unit) | 20.00 |
1 unit per point unless noted. Your broker's contract size and live price are what count.
NAS100 volatility and prop firms
The Nasdaq can gap overnight and move 100 points in a session. A 50-point stop is tight in the first hour; size for the stop you actually use. On a prop-firm account, index CFDs often have their own leverage and overnight rules: check the firm's list and leave room for the daily loss with the challenge planner.
What the calculator does not include
Spread, commission, overnight financing, slippage and the broker's contract differences. The result is the size for the stop you enter, before those costs.

Use the challenge planner for the daily and max loss, and remember that index CFDs may have their own leverage and overnight rules. Leave room for a gap; a 50-point stop is tight in the first hour.
