Prop firms design drawdown structures to test institutional precision. Manual calculation errors or spreadsheets lead to accidental account termination even when your strategy is profitable.
Your drawdown floor moves up automatically when your floating equity hits a new peak during the day—but it never moves back down when you lose. One emotional trade blows the evaluation challenge instantly.
Did you know a 5-lot trade on a 10-pip stop loss actually costs you an extra $35 in broker execution fees? If your remaining daily buffer is tight, commissions alone will trigger a breach.
Calculating dynamic risk across Forex major pips, Crypto coin contracts, and Futures ticks while managing high-stakes live volatility is a recipe for mathematical disaster.
Select your asset (Forex, Indices, Crypto, or Futures). Input your Stop Loss in pips, points, or ticks. Instantly get your exact maximum lot size or contract volume—mathematically capped and adjusted for commissions to protect your daily buffer.
Visualize exactly where your account failure point is before the trading day begins, whether your firm uses Static, EOD Trailing, or Real-Time Trailing rules.
Down 3% on the week? The terminal tells you exactly how many 2R trades you need to mathematically recover your account balance safely without over-leveraging.
Day Start Balance = Current Balance - Today's Floating PnL
Never guess your daily baseline. If your balance reads $102,000 with +$2,000 open profit from today, your true 00:00 CE(S)T Starting Balance is precisely $100,000.
No more confusing spreadsheets, external PDFs, or guessing how your firm calculates drawdown. Our terminal includes a complete 7-part Institutional Self-Help Master Guide inside the app with interactive tabs.
A single $100k evaluation challenge costs $500. Blowing it due to a lot-size miscalculation costs you time, money, and your payout.
Blowing one $100,000 evaluation challenge = -$500 lost fee + weeks of wasted effort. Protecting your account for life = $99 one-time.
