Step by Step Guide How to Backtest an MT5 EA Accurately Using Every Tick Data

Why Every Tick Based on Real Ticks Is Non Negotiable

1. Open prices only: Fast but completely unreliable. It only inspects the open of each candle completely ignoring intrabar volatility, Stop Loss triggers and slippage.
2. 1 minute OHLC: Interpolates price action using 1 minute bars. It fails to reflect real order fills during rapid market expansions or news events.
3. Every tick: Generates synthetic ticks based on M1 bars. While better it still simulates tick movement mathematically rather than reflecting true broker liquidity.
4. Every tick based on real ticks (Gold Standard): Downloads real historical bid and ask prices from your broker. It uses changing spreads and accurately simulates stop loss and take profit executions.

Step by Step MT5 Backtest Setup

Step 1: Open Strategy Tester

1. Launch your MetaTrader 5 terminal.
2. Press Ctrl + R or navigate to View > Strategy Tester in the top menu.
3. Select Single test to test a specific pair and parameter set.

Step 2: Configure the Core Settings

• Expert: Select the EA you wish to test e.g QCL MT5 EA.
• Symbol: Select your trading instrument  e.g XAUUSD, EURUSD.
• Timeframe: Set the recommended operating timeframe  e.g M1 or M15.
• Date: Choose a custom period and test for 6–12 months across both volatile and low activity markets.
• Forward: Select No for an initial baseline verification or choose a forward period to test out of sample consistency.
• Delays: Select Random delay  e.g  50–100 ms to mimic real world broker execution latency and slippage.
• Modeling: Choose  Every tick based on real ticks.
• Deposit & Currency: Enter your realistic initial deposit e.g $600 or $10,000 to mirror your intended live or prop firm balance.
• Leverage: Set your broker’s actual leverage e.g., 1:30, 1:50, or 1:100.
• Optimization: Select Disabled to run a direct raw test of the default strategy logic
  

Step 3: Calibrate the Inputs

1. Click the Inputs tab.
2. Make sure Auto Lot Sizing uses a fixed risk level such as 1% per trade.
3. Make sure the stop loss and take profit match the live settings.

Step 4: Run the Test & Analyze the Report

• Max Equity Drawdown (%): For prop firm readiness this should comfortably remain well below 5% to 8%.
• Profit Factor: Good trading models often have a profit factor between 1.4 and 2.2 over many trades.
• Win Rate vs. Risk:Reward: Make sure the system does not need a 99% win rate to make a profit. Good trading systems use a balanced win rate and proper Stop Losses.
• Recovery Factor: Measures how quickly the account exits drawdown periods without doubling lot sizes.
