Sweet spot for your $1,500 of room: 3–5 MNQ (each stop about 10–15% of your room).
Easiest way to set it: choose 10x and tap 100% for about 4 MNQ, or keep 50x and tap about 24%. Perp platforms that quote NQ at $1 per point show this as about 10.0 NQ.
$10 per point. A 20-point stop costs $200.

Room = the smaller of your daily loss limit and max drawdown. Wider stop? Cut the size to match. A 40-point stop halves every number.
Reference index price: 31,250 for these examples; your calculator uses the price you enter.
- 10x at 100% = 50x at 20% = 4 MNQ ($250,000)
- 25x at 50% = 50x at 25% = 5 MNQ ($312,500)
- 25x at 100% = 50x at 50% = 1 NQ ($625,000)
Pick the setting where 100% is the most you'd ever trade, so one wrong tap can't oversize you.
