Why Your Backtest Is Lying to You: The Discipline of Realistic MT5 Testing

from Forex Trading Systems Lab · host 1KPIPS

Many traders are misled by "beautiful backtest curves" and high profit factors that completely fail in live trading. In this episode, we break down why the MetaTrader 5 Strategy Tester is often too "forgiving" and how it produces "good-looking lies" when historical data is incomplete or spreads are fixed. Join us as we explore the 1kPips approach to making your testing models as "hostile and realistic as possible". We cover how to avoid the "optimization trap," why 99% modeling quality isn't a guarantee, and why backtesting should be about discovering how you might be wrong, rather than proving you are right.
