Phidias PropFirm $25,000 Challenge — Position Size Calculator

Quick Answer

Firm Rules Summary

Risk Guide

The Phidias PropFirm $25k challenge presents a unique scenario with zero daily loss limits and zero max drawdown restrictions, fundamentally changing traditional position sizing approaches. Unlike conventional prop firms where you'd breach limits after 4-5 losing trades at 2% risk, here you face no such mathematical constraints during the challenge phase. With no daily loss limit, you could theoretically lose $25,000 in a single day and still continue trading. At 1% risk per trade ($250), you'd need 100 consecutive losses to deplete the account. At 2% risk per trade ($500), you'd need 50 consecutive losses. This unlimited risk tolerance means position sizing becomes purely about your personal risk management rather than firm restrictions. For practical position sizing: EURUSD with a 30-pip stop allows 8.33 standard lots at 1% risk ($250 ÷ $3 per pip). GBPJPY with a 50-pip stop allows 1.25 standard lots at 1% risk ($250 ÷ $200 per pip movement). Gold with a $20 stop allows 12.5 standard lots at 1% risk. The danger scenario here isn't breaching firm limits—it's complete account destruction. Without firm-imposed guardrails, a few high-leverage revenge trades or poor risk management decisions could eliminate your entire $25,000 in hours. The absence of restrictions becomes the restriction: you must impose iron discipline on yourself. Position sizing math remains standard: Risk Amount ÷ (Stop Loss × Pip Value) = Position Size. However, the psychological challenge intensifies when you realize nothing prevents you from risking 10%, 20%, or even 100% per trade except your own discipline. Between challenge and funded phases, expect traditional restrictions to appear. Most prop firms implement daily loss limits and max drawdown rules on live accounts, so this unlimited freedom likely exists only during the evaluation phase. Use this period to demonstrate conservative risk management rather than exploit the unlimited risk tolerance.
