What is an Equity Curve?
An equity curve is a visual representation of your trading account's value over time. It plots the cumulative profit or loss from each trade, creating a line that shows how your account balance evolves. A smooth, upward-sloping equity curve indicates consistent profitability, while a jagged curve with deep valleys suggests high volatility and significant drawdowns.
Our free equity curve simulator uses Monte Carlo simulation to generate realistic trading scenarios based on your strategy parameters. By running multiple simulations with the same inputs, you can see the range of possible outcomes and understand how randomness affects trading results—even with a profitable strategy.
How to Use This Equity Curve Simulator
- 1
Set Your Starting Capital
Enter the amount you plan to start trading with. This is your initial account balance that will grow or shrink based on simulated trades.
- 2
Define Your Win Rate
Use the slider to set your expected win rate. This is the percentage of trades you expect to be profitable. Be realistic—most successful traders have win rates between 40-60%.
- 3
Set Risk-Reward Ratio
Enter your average reward-to-risk ratio. A value of 2 means you aim to make $2 for every $1 you risk. Higher ratios can compensate for lower win rates.
- 4
Configure Risk Per Trade
Set the percentage of your account you'll risk on each trade. Professional traders typically risk 1-2%. Higher risk leads to faster growth but also larger drawdowns.
- 5
Run Multiple Simulations
Click "Run Simulation" to generate equity curves. Each simulation shows a different possible outcome, helping you understand the range of results you might experience.
Understanding Trading Expectancy
Expectancy is a key metric that tells you how much you can expect to make (or lose) per trade on average. It's calculated as:
Expectancy = (Win Rate × Risk-Reward) - (1 - Win Rate)
A positive expectancy means your strategy is profitable over the long run. For example, with a 50% win rate and 2:1 risk-reward ratio, your expectancy is (0.5 × 2) - 0.5 = 0.5R, meaning you expect to make 0.5 times your risk per trade on average.
Why Use an Equity Curve Simulator?
