Author: [Your Name/Affiliation] Date: [Current Date] Subject: Algorithmic Trading, Foreign Exchange Markets Abstract The increasing complexity of foreign exchange (Forex) markets has driven retail and institutional traders toward automated strategy development. Forex Strategy Builder (FSB) — specifically referring to the open-source software Forex Strategy Builder Pro and its derivatives — is a visual, rule-based environment for designing, backtesting, and optimizing trading strategies without traditional programming. This paper examines the software’s core architecture, including its logic module system, multi-symbol backtester, and Monte Carlo simulation capabilities. We analyze its methodological strengths (transparency, strategy robustness testing) and limitations (overfitting risk, look-ahead bias potential). Finally, we propose a rigorous workflow for developing generalizable strategies using FSB, emphasizing out-of-sample validation and walk-forward analysis. forex strategy builder
