Custom indicators allow traders to go beyond standard tools and create tailored technical studies that reflect their unique trading strategies. These indicators are especially useful when traditional tools like RSI or MACD don't align with specific market conditions or personal styles. This course introduces traders to the logic, formulation, and implementation of custom indicators. It starts with the basics of what indicators are, how they interpret price action and volume, and why traders might need to build their own. You'll learn how to identify gaps in existing indicators and translate ideas into formulas using scripting platforms like Pine Script (for TradingView) or Python. Practical examples will walk you through designing indicators such as modified moving averages, multi-timeframe oscillators, and volume-weighted strategies. You'll also learn how to backtest your indicators and avoid common pitfalls such as overfitting. Whether you're a discretionary trader looking to create alerts or a quant exploring system-based signals, this course offers both foundational and practical skills.
