Quick Calculator Overview
Calculate realistic timelines for prop firm challenges that use Intraday Trailing Drawdown (ITDD) rules. This calculator helps prop traders and funded account users evaluate whether their trading strategy can reach profit targets while surviving the “erosion effect” of trailing drawdown rules that tighten your maximum loss limit with each winning day.
How to Use the Calculator
Step 1: Set Your Account Size
Enter your starting trading capital (typically $25K, $50K, $100K, or $150K depending on your challenge or funded account).
Step 2: Enter Your Profit Target
Input the total profit required to pass your evaluation or reach your trading goal (e.g., $3,000 for most $50K challenges).
Step 3: Input Maximum Loss Limit
Enter your starting maximum loss before account breach. This is usually $2,000-$3,000 for most prop firms.
Step 4: Define Your Daily Profit
Input your average profit on winning days based on your trading strategy and position sizing.
Step 5: Set Your Daily Loss
Enter your average loss on losing days, including all trading costs (commissions, spreads, slippage).
Step 6: Adjust Your Win Rate
Set your realistic win rate percentage based on backtesting or proven track record.
Step 7: Enter Average Intraday Run-Up
Input how much your trades typically go positive before you take profit (this simulates how trailing rules might tighten during run-ups).
Understanding Your Results
Success Indicators
🟢 Green Banner: “Profit Target Appears Achievable” – Your strategy should work within ITDD limits
🟡 Yellow Banner: “High Risk: Intraday Trailing Drawdown Likely to Fail” – Profitable strategy but ITDD erosion will likely stop you out
🔴 Red Banner: “Target unreachable with current parameters” – Strategy loses money over time
Calculator Limitations
- Provides teaching proxy for trailing drawdown concepts using simplified “wins-only erosion” model
- Assumes consistent daily performance (real trading involves variance and streaks)
- Doesn’t simulate actual intraday trailing mechanisms or daily equity curve fluctuations
- Uses rounded win/loss day estimates rather than precise broker ITDD rules
- Results depend entirely on accuracy of your input parameters
Market Factors Not Considered
- Complex broker-specific ITDD rule variations
- Psychological factors affecting performance during drawdown pressure
- Strategy adjustments that may occur when approaching limits
- Actual intraday price movements and trailing mechanisms
Frequently Asked Questions
01Which futures prop firms use intraday trailing drawdown rules?
Many major firms including Apex Trader Funding, Tradeify, Take Profit Trader and various other prop firm companies. Always verify your specific firm’s drawdown rules before using this calculator.
02Should I include all trading costs in my daily loss amount?
Yes, include commissions, platform fees, and any prop firm charges for realistic projections.
03What if my strategy shows “High Risk” despite being profitable?
This means trailing drawdown erosion reduces your loss limit faster than you build profits. Consider trading smaller size, taking profits sooner, or improving win rate.
04How does intraday trailing drawdown differ from end-of-day rules?
ITDD rules tighten your maximum loss limit in real-time as trades go positive, while EOD rules only adjust at market close based on account balance.
05Why do small changes in run-up amounts create dramatic differences?
Higher intraday run-ups accelerate the trailing drawdown erosion effect, potentially reducing your loss limit to zero much faster than you can build sustainable profits.
