SFX Funded $10,000 Challenge — Position Size Calculator

Quick Answer

Firm Rules Summary

Risk Guide

Your $10k SFX Funded account has a razor-thin $300 daily loss margin, making position sizing absolutely critical. At 1% risk per trade, you're risking $100 per position, which means just 3 consecutive losses wipe out your daily allowance. Bump that to 2% risk ($200 per trade) and you're down to 1.5 losing trades before breach - essentially one bad trade plus any spread costs puts you in violation territory. This is where most traders blow their accounts: they think 2-3% risk is conservative, but with SFX's tight daily limit, even two 2% losses ($400 total) exceed your $300 threshold. The math for popular instruments at 1% risk: EURUSD with 30-pip stop = 0.33 lots, GBPUSD with 40-pip stop = 0.25 lots, GOLD with 100-pip stop = 0.10 lots. For 0.5% risk (recommended), cut these positions in half. The danger scenario here isn't the 6% max drawdown - it's hitting that daily limit repeatedly. You could be profitable overall but still fail if you breach the daily rule multiple times. Unlike firms with reset mechanisms, every daily breach counts against you. Since SFX runs a single-phase challenge with 0% profit target, you might think you can trade aggressively, but the daily loss limit forces conservative position sizing regardless. The key difference between challenge and funded phases isn't the rules - they stay the same - but your psychology. In the challenge, you might be tempted to revenge trade after losses to 'make back' money quickly. With only $300 daily buffer, this mentality kills accounts fast. Your position sizing must account for spreads, slippage, and weekend gaps too. If you're risking exactly $100 per trade, a 10-pip slippage event pushes you closer to that daily limit faster than expected. Build in a buffer by risking 0.8% instead of the full 1%, giving yourself breathing room for execution costs while maintaining enough position size to generate meaningful profits.
