AI Strategy Backtester

Describe any trading strategy in plain English and the AI builds it, runs it against historical data, and plots every buy and sell signal on your chart — complete with performance stats like total return, win rate, Sharpe ratio, and max drawdown.

How It Works

Traditional backtesting requires coding skills — writing Pine Script, Python, or similar. ChartingLens eliminates that entirely. You describe what you want in natural language, and the AI does the rest.

Describe Your Strategy

Type your idea in plain English. For example: "Buy when RSI crosses above 30 and MACD is positive. Sell when RSI crosses above 70."

AI Builds the Code

The AI translates your description into executable strategy code, handling indicator calculations, entry/exit logic, and position management.

Backtest Runs

The strategy executes against the historical OHLCV data on your current chart. Every trade is recorded with entry price, exit price, and result.

Results on Chart

Buy and sell markers appear on the chart at exact trade locations. A summary panel shows total return, win rate, Sharpe ratio, profit factor, and max drawdown.

Performance Metrics

Every backtest produces a complete performance report so you can evaluate your strategy objectively.

Total Return — the overall percentage gain or loss from the first trade to the last
Win Rate — the percentage of trades that were profitable
Sharpe Ratio — risk-adjusted return, measuring how much excess return you get per unit of volatility
Profit Factor — gross profits divided by gross losses. A profit factor above 1.0 means the strategy was net profitable
Max Drawdown — the largest peak-to-trough decline during the backtest period, showing worst-case capital loss
Number of Trades — total buy/sell round trips generated by the strategy

Visual Equity Curve

In addition to the stats summary, the backtester shows a visual equity curve — a line chart of your account value over time. This lets you see not just the final result but the journey, including drawdown periods and recovery patterns.

Find Best Timeframe

Not sure which timeframe works best for your strategy? The "Find Best Timeframe" feature automatically re-runs your strategy across four timeframes — 15 minute, 1 hour, 4 hour, and 1 day — and compares results side by side.

One click runs the same strategy on 4 different timeframes
Results are ranked by total return so you can instantly see the best performer
Compare win rates, Sharpe ratios, and trade counts across timeframes
Useful for discovering that a strategy that underperforms on daily candles might excel on 4H or vice versa

Built-In Preset Strategies

10+ proven strategies are available as presets that you can run with a single click via the Quick Actions menu. All presets run instantly without using AI credits.

Golden Cross / Death Cross

Buys when the 50 SMA crosses above the 200 SMA and sells on the reverse. A classic trend-following strategy used by institutional traders.

RSI Mean Reversion (30/70)

Buys when RSI drops below 30 (oversold) and sells when RSI rises above 70 (overbought) with a 5% stop loss and 10% take profit.

MACD Crossover

Goes long when the MACD line crosses above the signal line. Exits on the reverse crossover or a 5% stop loss.

SMC Fair Value Gap Retest

Detects bullish and bearish Fair Value Gaps, enters on confirmed zone retests with 2:1 reward-to-risk. Draws all FVG zones on the chart.

20-Day High Breakout

Enters when price closes above the 20-period highest high. Exits when price closes below the 10-period lowest low.

Buy the Dip (5% Pullback)

Enters when price drops 5% from its recent high. Exits on a 5% recovery (take profit) or 5% further decline (stop loss).

Example Strategy Ideas

Here are some strategies you can describe in plain English for the AI to build and test:

"Buy when the price crosses above the upper Bollinger Band with volume above average. Sell after 5 candles or if price drops below the middle band."
"Buy when MACD histogram turns positive and ADX is above 25. Sell when MACD histogram turns negative."
"Buy when price closes above the 20 EMA and Stochastic is below 20. Sell when Stochastic crosses above 80."
"Buy on a bullish engulfing candle when RSI is between 40 and 60. Set a stop loss at the low of the engulfing candle."
