Technical Indicators

Core Mechanics and Moving Averages

1. Smoothing Market Noise

The Rubber Band Mental Model: Think of indicators like the Relative Strength Index (RSI) and Bollinger Bands as a rubber band. When the price stretches too far away from its average centre, tension increases until the rubber band inevitably snaps back toward the middle.

Simple vs. Exponential Averages: Moving averages smooth out price data to reveal underlying trends over specified periods. The Simple Moving Average (SMA) calculates average price with equal weighting, while the Exponential Moving Average (EMA) places heavier weight on recent prices, making it more responsive to sudden shifts in sentiment.

2. Essential Volatility and Range Metrics

Bollinger Bands: Composed of a moving average flanked by standard deviation bands that expand and contract based on market volatility. A period of ultra-narrow bands  - known as a "squeeze" - frequently precedes massive trend breakouts.

Average True Range (ATR): Measures the absolute range of price movements over a set period without indicating trend direction. Traders rely on the ATR to dynamically size positions and set realistic stop-loss boundaries based on current market volatility.

Momentum, Reversals, and Market Structure

1. The Relative Strength Index (RSI)

Measuring Magnitude: The RSI is a momentum oscillator measuring the speed and change of recent price shifts on a scale from 0 to 100 over a standard 14-day period.

Overbought and Oversold Tiers: Readings above 70 indicate that a security may be overbought and due for a correction, while readings below 30 suggest oversold conditions and potential buying opportunities.

2. Advanced Trend and Reversal Tools

Parabolic SAR: Plots dots above or below price action to track trend direction dynamically, serving as a reliable trailing stop-loss reference point.

The Ichimoku Cloud: A comprehensive indicator combining multiple lines and a shaded cloud to outline trend direction, momentum, and dynamic support and resistance zones all at once.

Strategic Integration and Indicator Redundancy

1. Leading vs. Lagging Indicators

Lagging Indicators: Metrics like moving averages and the MACD rely on past data to confirm ongoing trends, providing stability at the cost of real-time speed.

Leading Indicators: Oscillators like the RSI and Stochastic Oscillator attempt to anticipate price shifts before they happen, helping traders prepare for reversals.

2. The Signal Filter Pro-Tip

Avoiding Redundancy: Using three different indicators that all measure the same thing—such as RSI, Stochastics, and CCI for momentum—does not improve your edge; it simply repeats the same data.

Diversified Stack: Combine one trend indicator, one momentum indicator, and one volatility indicator for a balanced, holistic view of market health.

Key Takeaways

Decode Market States: Use moving averages to track trends, Bollinger Bands to measure volatility, and RSI to gauge momentum extremes.

Respect Indicator Lag: Recognise that lagging indicators confirm ongoing moves, whereas leading oscillators help anticipate turning points.

Avoid Redundancy: Stack non-correlating indicators (trend, momentum, and volatility) rather than cluttering charts with identical tools.

Demand Confluence: Always validate indicator signals using support and resistance levels, volume dynamics, and broader chart patterns.
