Why Real-Tick Backtesting Matters for MT5 EAs
If you have ever seen two backtests of the "same" EA produce wildly different equity curves, the cause is almost always modelling quality.
The Three Modelling Modes
- Open prices only — fast but unrealistic; ignores intrabar movement.
- 1 minute OHLC — better, but still interpolates ticks.
- Every tick based on real ticks — the gold standard, using actual recorded ticks.
Why Spread Modelling Matters
Scalping systems live and die on spread. A backtest with a fixed 0-point spread is fiction. Realistic, variable spread modelling is essential to trust the numbers.
Robustness Over Perfection
A believable backtest is one that stays profitable across multiple brokers and starting balances, with a stable drawdown. That is exactly the standard PythonX systems are validated against.
The PythonX team builds and verifies MetaTrader 5 Expert Advisors with real-tick backtesting and multi-broker validation. Every system ships with published backtest reports and live results.
