Frequently Asked Questions

What is Monte Carlo simulation in trading?

Monte Carlo simulation runs thousands of randomized scenarios using your actual trading statistics — win rate, average win, average loss — to show the full range of possible outcomes. Instead of one optimistic projection, you see best-case, worst-case, and everything in between.

Are these tools really free?

Yes, 100% free with no signup required. We built these tools to help traders make better decisions with real math.

How accurate are the simulations?

The simulations are as accurate as your inputs. Enter your real win rate and average win/loss for realistic projections. The model assumes independent trades with consistent statistics.

How do I calculate my position size?

Enter your account balance, the percentage you want to risk per trade (typically 1-2%), and your stop loss distance in points or pips. The calculator divides your dollar risk by the per-unit risk to give you exact share or contract count.

How long does it take to recover from a trading drawdown?

It depends on your win rate, average win/loss ratio, and drawdown depth. A 20% drawdown needs a 25% gain to recover. A 50% drawdown needs 100%. Our Monte Carlo calculator simulates realistic timelines based on your actual stats.

Do I need a TradeZella account to use these calculators?

No. These tools are completely standalone and free. If you want to track your actual trading performance and get automatic analytics, TradeZella offers that as a separate platform.

What markets do these calculators work for?

All of them — stocks, options, forex, futures, and crypto. The position size calculator adjusts for any instrument type. The drawdown and ROI calculators work with any market since they use percentage-based inputs.
