AutoPilot Trader Risk Calculator & Position Sizing Guide
Calculate Your Position Size in 60 Seconds
Position sizing determines whether your AutoPilot Trader strategy succeeds or fails. Not your win rate. Not your strategy selection. Your contract size.
The data is clear: Traders with mean drawdowns under 25% of account balance have a 94% survival rate after 12 months. Above 50%? Only 31% survive. Above 75%? Just 9% make it past 6 months.
This calculator uses real performance data from 955+ verified trades to show you exactly where you stand.
Quick Start: 3 Steps to Your Risk Profile
Enter your account size (for prop accounts, use your max drawdown limit, not buying power)
Select your contract quantity (start with 3 MNQ for prop accounts)
Check your Safety Rating (aim for GOOD or EXCELLENT)
How to Interpret Your Results (Critical)
Your calculator results show 9 metrics, but only 3 determine your trading survival. Focus here:
1. Mean Drawdown % of Balance (Your Most Critical Number)
This shows your typical worst-case loss as a percentage of your account. Here's what the survival data shows:
0-20%: Low risk, sustainable long-term (recommended for most traders)
20-40%: Moderate risk, acceptable for experienced traders with strong psychology
40-60%: High risk, requires exceptional discipline and backup capital
60%+: Severe risk, statistical probability of account failure
If this number makes you uncomfortable, reduce contracts immediately. This isn't a rare event—it's what you'll regularly experience.
2. Safety Rating (Your Quick Health Check)
EXCELLENT/GOOD: Green light. Recommended for sustainable trading.
MODERATE: Yellow light. Acceptable for experienced traders only. Know what you're getting into.
ELEVATED/HIGH: Red light. High risk, not recommended unless you have exceptional risk tolerance and backup capital.
SEVERE: Stop. Almost certain account failure. Reduce position size or increase capital.
3. 95th Percentile Drawdown (Your Disaster Test)
This is the worst-case scenario with only 5% probability of exceeding. Ask yourself:
"If I lost $X tomorrow, would I panic and shut down the system?"
If yes, you're oversized. The math works, but psychology will sabotage you before the system recovers.
The One Rule That Predicts Success
After analyzing hundreds of automated trading accounts, one pattern is undeniable:
Mean DD under 25% = 94% survival rate at 12 months Mean DD over 50% = 31% survival rate at 12 months
This isn't about trading skill. It's about position sizing enabling you to survive drawdowns without panic.
Why Position Sizing Matters More Than Your Strategy
Most traders obsess over finding the perfect strategy while ignoring the math that actually determines success. Here's the reality: even a 74% win rate strategy can destroy your account if you're improperly sized.
Position sizing isn't generic "risk 2% per trade" advice. It's about understanding:
Your actual account drawdown tolerance (not what you think you can handle)
Strategy-specific risk characteristics (different strategies drawdown differently)
Statistical probability of hitting your maximum loss (what "could" happen vs. what "will" happen)
How contract size scales with account balance (doubling contracts doesn't just double returns)
Get this wrong, and no amount of strategy optimization will save you.
The Automated Trading Position Sizing Problem
Manual traders can adjust position size trade-by-trade based on market conditions and personal risk tolerance in the moment. Automated traders don't have that luxury.
When you deploy AutoPilot Trader:
Position size is set once and runs continuously (unless you manually intervene)
The system executes 1-3 trades daily on autopilot
You can't "scale down" mid-drawdown without stopping the entire system
Every configuration decision compounds over hundreds of trades
This makes precise position sizing calculation essential, not optional. You're setting and forgetting—the math must work from day one.
What Makes This Calculator Different
Traditional position sizing calculators use generic assumptions and theoretical drawdowns based on textbook risk management principles.
Our calculator uses actual backtest data from AutoPilot Trader strategies:
✅ Real drawdown statistics from 12 months of live trading data ✅ 9 different strategy configurations with verified results ✅ Monte Carlo analysis showing 95th percentile worst-case scenarios
✅ Calculations based on 3 NQ (30 MNQ equivalent) backtest data
When the calculator shows you a risk level, that's not a theoretical estimate—it's statistical probability based on 955+ real trades.
Step-by-Step: Using the Calculator Correctly
Step 1: Determine Your TRUE Account Size
This is where most traders make their first mistake.
For personal trading accounts:
Enter your actual account balance. Simple.
For prop firm accounts:
Enter your maximum allowed drawdown, NOT your buying power.
Critical for prop traders: A $150K prop account with $4,500 max drawdown has a true risk capital of $4,500. The $150K is leverage for buying power, not loss tolerance. The prop firm will shut you down at $4,500 loss regardless of the $150K in buying power.
Always calculate based on max drawdown limits, not account size.
Step 2: Select Your Contract Size
AutoPilot Trader strategies were backtested with 3 NQ contracts (equivalent to 30 MNQ).
Position sizing guidelines:
Prop firm accounts: Start with 3 MNQ (proven safe across all strategies)
Personal accounts ($5-10K): 3-6 MNQ depending on risk tolerance
Personal accounts ($10K+): 6-12 MNQ based on risk appetite
Important: Most strategies require contracts in multiples of 3.
Contract conversion reference:
30 MNQ = 3 NQ (10:1 ratio)
1 NQ = 10 MNQ
1 YM = 10 MYM
Step 3: Review Multiple Contract Quantities
Don't just test one position size. Run scenarios with 3, 6, 9, and 12 MNQ to see how risk scales.
This reveals the critical insight: risk doesn't scale linearly. Doubling contracts from 3 to 6 MNQ doesn't just double your returns—it doubles your drawdowns and often moves you from GOOD to ELEVATED risk.
Step 4: Choose the Conservative Option
When multiple position sizes show acceptable risk levels (GOOD or EXCELLENT), choose the smaller size.
Why? You can always scale up after you've built confidence and profit buffer. You cannot recover from a blown account.
The goal isn't maximum returns—it's consistent returns over 12+ months.
Common Position Sizing Mistakes (And How to Avoid Them)
Mistake #1: Using Buying Power Instead of Risk Capital
The error: Prop firm traders enter $150K (their buying power) instead of $4,500 (their max drawdown limit).
Why it matters: The calculator shows "low risk" with 6 NQ contracts on a $150K account. In reality, a single bad day could violate your $4,500 max loss rule and get you shut down.
The fix: Always enter your maximum allowed loss, not your leverage.
Mistake #2: Planning to "Scale Down If Losing"
The error: Starting with 12 MNQ and planning to reduce to 6 MNQ if you hit a drawdown.
Why it matters: By the time you scale down, you've already taken the large losses. Starting large and "scaling down if you lose" means you've already lost.
The fix: Start small, scale up from profits only.
Mistake #3: Ignoring Strategy-Specific Drawdowns
The error: Applying generic "2% risk per trade" advice across all AutoPilot Trader strategies.
Why it matters: The 5min PT2 strategy has dramatically different drawdown characteristics than the 2min 20pt Stop strategy. Generic advice doesn't account for this.
The fix: Calculate position size independently for each strategy using actual backtest data (which this calculator provides).
Mistake #4: Treating All Contracts Equally
The error: "If 3 MNQ works well, 6 MNQ will just make twice as much money."
Why it matters: Going from 3 to 6 MNQ doesn't just double your returns—it doubles your drawdowns AND increases the probability of hitting your maximum loss threshold.
The fix: Use the calculator to see the actual impact. The Safety Rating often drops from GOOD to ELEVATED just by doubling contracts.
Mistake #5: Trusting High Win Rates = Low Risk
The error: "This strategy has a 74% win rate, so risk is low regardless of position size."
Why it matters: Win rate doesn't prevent drawdowns. A 74% win rate means 26 out of 100 trades lose. When those losing trades cluster (which they statistically will), you experience drawdown.
The fix: Win rate is already factored into the calculator's statistical models. Follow the Mean DD % and Safety Rating, not just win rate.
Position Sizing for Prop Firm Challenges
Prop firm trading requires special position sizing considerations due to strict drawdown rules and evaluation pressure.
Key Constraints You're Operating Under:
Maximum daily drawdown rules (often $2,000-$3,000)
Maximum total drawdown limits (typically $4,500-$6,000)
Time pressure to hit profit targets (need $X profit within Y days)
No ability to add capital (if you violate rules, you're done)
Recommended Prop Firm Approach:
Enter max drawdown as your "account size" in the calculator (not buying power)
Use lowest-drawdown strategies first (MYM, Long0Only)
Start with 3 MYM or 3 MNQ minimum (proven safe across all strategies in backtest data)
Only scale up after passing evaluation or building significant profit buffer
Never exceed MODERATE risk rating during evaluation period
Reality Check for Prop Traders:
90% of prop firm failures are position sizing errors, not strategy failures. The AutoPilot Trader strategies have proven 74% win rates and consistent profitability over 955+ trades. But that doesn't matter if you're oversized and violate drawdown rules in week one.
The prop firm gave you $150K in buying power, but they gave you $4,500 in loss tolerance. Trade accordingly.
Position Sizing FAQ
Q: Can I use different position sizes for different strategies?
Yes, and you should. Each AutoPilot Trader strategy has unique drawdown characteristics. The calculator lets you test each independently. Some strategies are more aggressive (higher returns, higher drawdowns), others are more conservative.
Q: Should I reduce position size during drawdown periods?
No. Automated strategies require consistency. Changing position size mid-strategy introduces variables that weren't present in the backtest data. The drawdowns are already factored into the statistical models—the system is designed to trade through them.
Size correctly from the start, then let it run.
Q: How often should I recalculate position size?
Recalculate when:
Your account grows or shrinks by 25% or more
You switch to a different AutoPilot Trader strategy
You move from personal account to prop firm (or vice versa)
Your risk tolerance changes significantly
Q: What if the calculator shows all ELEVATED or SEVERE ratings for every contract quantity I test?
Your account is too small for your desired contract size. You have two options:
Increase your trading capital (add more funds or qualify for larger prop account)
Reduce contracts to 3 MYM and opt for “Long-Only”
There's no way to trade AutoPilot Trader strategies "safely" if the math shows SEVERE risk. The statistics don't lie.
Q: Can I trade fractional contracts?
Most AutoPilot Trader strategies require contracts in multiples of 3 (3, 6, 9, 12 MNQ). This is due to the strategy logic for managing multiple positions.
Q: How accurate is the calculator's risk prediction?
The calculator uses actual backtest data from 955+ verified trades over 12 months. The Mean Drawdown shown is the actual average drawdown experienced during backtesting, not a theoretical estimate.
However, past performance doesn't guarantee future results. Use the calculator for risk assessment and sizing guidance, not as a profit guarantee.
Q: What if my actual results don't match the calculator predictions?
Over a sufficient sample size (90+ trades minimum), your actual results should align with calculated expectations. If they don't:
You may be in a statistical outlier period (normal variation)
Your execution may differ from backtest conditions (slippage, fill rates)
Market conditions may have changed significantly since backtest period
Track actual vs. predicted performance. If discrepancies persist beyond 200 trades, reassess.
Your Position Sizing Action Plan
Follow this 5-step process to deploy AutoPilot Trader with mathematically sound position sizing:
1. Calculate Multiple Scenarios
Use the calculator to test several contract quantities:
3 MNQ (baseline safe size)
6 MNQ (moderate size)
9 MNQ (aggressive for larger accounts)
12 MNQ (high risk, experienced traders only)
Record the Mean DD %, Safety Rating, and Risk Level for each.
2. Identify Your Risk Ceiling
Find the highest contract size where ALL of these conditions are met:
Mean DD % stays under 30-40%
Safety Rating shows GOOD or EXCELLENT
Risk Level under 10%
You can emotionally handle the 95th Percentile DD dollar amount
If none of your scenarios meet all criteria, reduce contracts or increase capital.
3. Choose Conservative When in Doubt
If multiple contract quantities show acceptable risk profiles, choose the smaller size.
Example: Both 6 MNQ and 9 MNQ show GOOD ratings, but 6 MNQ shows 22% Mean DD while 9 MNQ shows 35% Mean DD. Choose 6 MNQ.
You can always scale up after building profits. You cannot undo a blown account.
4. Document Your Decision
Write down:
Your chosen contract size (e.g., "6 MNQ")
Your selected strategy (e.g., "NQ Long Only V3")
Your calculated Mean DD % (e.g., "22% of account")
Your calculated 95th Percentile DD (e.g., "$4,200 worst case")
Commit to this size for at least 90 days of automated trading before making changes.
Why 90 days? Drawdowns are normal. You need sufficient sample size to distinguish between "normal statistical variation" and "something is wrong."
5. Monitor Performance vs. Predictions
Track these metrics weekly:
Actual drawdown vs. Mean DD prediction
Actual returns vs. Annual Return projection
Number of trades vs. expected trade frequency
Over time (90-180 days), your actual results should converge toward calculator predictions. If they don't, investigate execution issues or market regime changes.
Why Proper Position Sizing Enables Automation Success
The promise of automated trading is freedom—freedom from screen time, emotional decisions, and manual execution stress.
But automation only delivers that freedom when you're properly sized.
Undersized: You're leaving money on the table unnecessarily. Your account could handle more risk, but you're trading too small out of fear.
Properly sized: The system runs smoothly. Drawdowns don't panic you. You trust the process. You let the automation work. This is the goal.
Oversized: Every drawdown triggers stress. You constantly consider stopping the system. You check your account compulsively. You sabotage your own success by interfering.
The AutoPilot Trader strategies are proven. The 74% win rate is documented across 955+ trades. The $166,708 annual returns (NQ Long Only V3) are based on real backtest data.
But none of that matters if you're improperly sized.
Proper sizing isn't about reducing returns—it's about enabling the psychological trust required for automation to work. You can't automate what you don't trust. You can't trust what makes you panic.
Use the calculator. Find your number. Let the system work.
