NNFX Backtest C1: Free MT4 Expert Advisor

Overview

NNFX Backtest C1 enables users to backtest custom indicators by defining signal logic such as two-line crossovers, zero-line crosses, or histogram changes. The system manages risk through ATR-based stop losses and take profits, with lot sizing based on a user-defined percentage of account balance or equity. This tool is strictly restricted to the Daily timeframe and includes optimization support to identify effective indicator parameters.
