Let me guess – you’ve been running backtests on MT5, getting incredible results, then watching your live account bleed money. And you’re wondering what the hell went wrong.
Here’s the truth most traders won’t tell you: 97% of traders use the wrong backtest settings. They’re essentially testing their strategies in a fantasy world that doesn’t exist.
The Four Types of MT5 Simulation (And Why Most Traders Pick Wrong)
MT5 offers four distinct simulation modes, each with dramatically different accuracy levels: “Open Prices Only” for quick rough estimates, “1 Minute OHLC” using the four primary price points of each minute bar, “Every Tick” with simulated ticks generated from M1 OHLC data, and “Every Tick Based on Real Ticks” using actual historical tick data from brokers.
Let me break this down in terms you actually care about:
1. Open Prices Only – The Speed Demon
This mode is the fastest but least accurate, suitable only for quickly finding gross logic errors or backtesting very long-term strategies over decades. It’s like testing a race car in a parking lot – sure, it runs, but you have no idea how it’ll perform on the track.
2. 1 Minute OHLC – The False Friend
This mode uses only Open, High, Low, and Close prices of minute bars, allowing for quick estimated test results. Here’s the problem: Traders report getting amazing results with 1 Minute OHLC – like $50K profit in a year – then switching to real ticks and seeing a $90K loss.
Why? The testing software makes your 1M OHLC backtest look much better than real results because it interpolates what happens between those 4 values, giving you perfect entries at your asking price and perfect exits even without the actual data near your TP or SL.
3. Every Tick – The Simulator
Every Tick uses virtual or simulated ticks generated from M1 OHLC data and ignores real tick data. It’s better than OHLC, but still living in simulation land. Think of it like a flight simulator – helpful for practice, but not the same as flying a real plane.
4. Every Tick Based on Real Ticks – The Reality Check
Testing on real ticks is the most accurate but time-consuming mode, using actual historical data. The tester uses tick data from the broker to simulate price movements as accurately as possible.
The Brutal Truth About Backtest vs Reality
Even with real tick data, your backtest is still lying to you. Here’s what it’s not showing:
Slippage – The Silent Killer
Slippage can be as low as 0.1% in liquid markets or well above 1% when liquidity thins out, rising with bigger order sizes and during volatile sessions. In simulated trading and backtests, slippage is not accounted for because they don’t consider order book depth or asset liquidity.
Think about it: There’s a delay between when your order is placed and when it’s executed – even if it’s only a fraction of a second, the market price may have changed or the spread may have widened.
Variable Spreads – The Shape Shifter
The spread is the difference between the buying (ask) and selling (bid) price, and it’s the cost traders pay for executing trades. Your backtest probably uses fixed spreads. Reality? Spreads widen during news events, low liquidity periods, and market opens.
Broker Execution – The Wild Card
Different brokers modify data for their purposes – if you’re not following their data, you’re trading blind, and all that talk about better tick data is nonsense when your broker’s data is different.
But Here’s Where It Gets Interesting…
Despite all these limitations, a properly conducted backtest is still your best predictor of success. It’s not about getting perfect results – it’s about finding strategies robust enough to survive reality’s punches.
Case in point: The Ratio X Quantum AI.
We ran it through the most brutal backtest conditions possible on XAUUSD (Gold) from July to September 2025. The results?
- Starting Capital: $30 (yes, thirty dollars)
- Net Profit: $13,642.69
- Return: 45,475% in 3 months
- Win Rate: 97.48%
- Total Trades: 25,249
- Profit Factor: 4.36
- Sharpe Ratio: 17.74
- Maximum Drawdown: 0.65% (Equity)
- Recovery Factor: 383.01
Now, before you mortgage your house, let me be clear: These are backtest results. Real trading will be different. But here’s what makes these numbers significant:
The EA executed over 25,000 trades. That’s not curve fitting – that’s statistical significance. The 97.48% win rate with a 4.36 profit factor means it’s not just winning often, it’s winning big when it does.
Most importantly, that 0.65% maximum drawdown tells you this isn’t a martingale time bomb waiting to blow up your account. It’s using sophisticated AI-driven position sizing and multi-timeframe analysis.
How The Pros Actually Use Backtesting
The rule for testing time and accuracy: The faster the test, the lower the trading simulation accuracy – the higher the price development accuracy, the more time is required to conduct a test.
Here’s my proven testing protocol:
Step 1: Quick and Dirty with OHLC
Start with 1 Minute OHLC to quickly eliminate obviously broken strategies. If it doesn’t work here, it won’t work anywhere. This takes minutes, not hours.
Step 2: Reality Check with Every Tick
If it passes OHLC, run it on Every Tick mode. Expect a 30-50% performance drop. If it’s still profitable, you might have something.
Step 3: The Final Test – Real Ticks
Use “Every tick based on real ticks” mode for sensitive order management features like TrailingStop and BreakEven, especially when StopLoss, TakeProfit, and Martingale Step sizes are smaller than average M5 bars.
Step 4: Add Reality Factors
For conservative testing, add 0.5-3.0 pip slippage range and consider factors like trading during thin markets, news events, and using market orders.
The Strategy That Changes Everything
The Ratio X Quantum AI isn’t just another EA – it’s built specifically to handle the gap between backtest and reality. Here’s how:
- AI-Driven Adaptation: Three-level dynamic trailing stop that adjusts to market conditions
- Multi-Timeframe Confluence: Confirms signals across multiple timeframes (70% threshold)
- Smart Position Sizing: Kelly Criterion with 0.25 fraction for optimal growth
- Risk Management: Three-tier drawdown limits (5%, 10%, 15%)
- Market-Aware Execution: Trades during optimal hours (avoiding low liquidity)

The Practical Tips That Actually Matter
After analyzing thousands of backtests, here’s what actually moves the needle:
1. Test on Your Broker’s Data
Your broker’s data – the data your trades follow – is different from other sources, so data from somewhere else is worthless. Always backtest using the broker you’ll trade with.
2. Focus on Robustness, Not Perfection
For EAs aiming for fewer trades with bigger returns in pips, backtesting can give more realistic results compared to micro-scalping strategies that are spread sensitive.
3. The 100-Trade Minimum Rule
Never trust a backtest with fewer than 100 trades. Statistical significance starts at 30, but real confidence comes at 100+. The Ratio X Quantum AI? 25,249 trades. That’s confidence.
4. Compare All Modes
When you obtain similar results in OHLC, Every Tick, and Every Tick Based on Real Ticks, then you can be sure your next step is to put it on a real account.
5. Add 20% More Slippage Than You Think
Always overestimate slippage in the backtest because you don’t want to design a system and then have it be much worse than expected. If you think 1 pip, use 1.2 pips.
6. Test Different Market Conditions
Test strategies under different market conditions to evaluate consistency and profitability. Don’t just test the bull market of 2024. Test the COVID crash. Test the 2022 bear market.
7. Watch Your Execution Timing
Long delays in execution can result in higher slippage, negatively impacting your trade. If your strategy relies on precise timing, add execution delays to your backtest.
The Bottom Line
Backtesting isn’t about finding the perfect strategy. It’s about finding strategies robust enough to survive when everything goes wrong.
We’ve all seen hundreds of robots that obtained spectacular results in backtesting, but when operating in real accounts the results were very bad. The difference? They weren’t tested properly.
The Ratio X Quantum AI’s 45,475% return isn’t just a number – it’s 25,249 trades of proof that the strategy works across different market conditions. Will you get exactly 45,475% in live trading? No. But with proper risk management and realistic expectations, you’re looking at a system that’s proven its edge.
Stop looking for the perfect backtest. Start looking for strategies that survive imperfect conditions. That’s where real money is made.

Remember: Past performance doesn’t guarantee future results. Always test thoroughly and trade responsibly.
