Strategy Backtester

The Truth in the Data

Stop Guessing, Start Verifying

The difference between a gambler and a professional is the **Certainty of Edge**. A gambler hopes the next trade works. A professional knows that over the next 1,000 trades, they will be profitable because they have the data to prove it.

The Drawdown Strategy Backtester is designed to be the "Truth Machine" for your trading plan.

Eliminating Observer Bias

Human beings are wired to seek patterns that confirm their existing beliefs. This is called "Confirmation Bias". When you scroll back on TradingView, you subconsciously ignore the losing trades that 'almost' met your criteria and focus on the clean winners.

Our backtester removes the human. It executes your rules exactly as written. If your rule says "Buy at the break of the high", it buys every single one. No hesitation, no "this time looks different". This is the only way to find your *True* Win Rate.

The Monte Carlo Reality Check

A backtest might show you a 60% win rate over 100 trades. But what if those 40 losses all happen at the same time? That is called a "Sequence of Returns" risk.

Multi-iteration **Monte Carlo simulations** take your trade results and shuffle them thousands of times. It shows you the probability of hitting a 10% drawdown or a 50% drawdown based on your data. This is how you determine your "Maximum Risk of Ruin". If your strategy has a 5% chance of blowing your account, you shouldn't trade it. We give you that number.

Curve Fitting: The Silent Killer

The biggest trap in backtesting is "Optimising" your strategy so much that it perfectly fits the past but fails in the future. This is called **Curve Fitting**.

We prevent this through **Walk-Forward Analysis**. We test your strategy on one period of data, then "validate" those settings on a completely different period that the engine hasn't seen yet. If the strategy only works in 2021 but fails in 2022, it's not an edge—it's just a coincidence.

Survivorship Bias & Slippage

Most retail backtesters ignore the cost of doing business. They assume you get filled at the exact price on the screen. In reality, you pay spread, and you experience slippage during high volatility.

Our engine models **Variable Transaction Costs**. We simulate the widening of spreads during news events and the delay in execution during low-liquidity periods. We show you your *Net Profit*, not just your Gross Profit. Because you can't pay your bills with Gross Profit.
