Technical Indicators: RSI, MACD, EMAs, Bollinger Bands & ATR

Comprehensive guide to mathematical technical indicators: Relative Strength Index (RSI Divergences), MACD Crossovers, Exponential Moving Averages (20/50/200 EMA), Bollinger Bands (Squeezes), and Average True Range (ATR) volatility stops.

★ Core Mathematical Formula / Operational Rule:RSI = 100 - [100 / (1 + RS)] | MACD Line = 12 EMA - 26 EMA | ATR Sizing Stop = Entry Price - (2.0 × 14 ATR)
Core Key Takeaways
1RSI (14) measures momentum velocity; RSI Divergence (Price lower low + RSI higher low) signals high-probability reversals.
2MACD measures trend convergence/divergence through the difference between 12 and 26-period EMAs.
3Exponential Moving Averages (20/50/200 EMA) identify macro trend regime (Golden Cross = 50 EMA crosses above 200 EMA).
4Bollinger Bands identify volatility cycles; Band Squeezes precede explosive directional volatility expansion.
5Average True Range (ATR) measures market volatility in absolute rupees, essential for dynamic stop-loss placement.

How the Mechanism Operates

Indicators are mathematical transformations of price, volume, and time. They fall into three distinct functional categories:

Trend-Following Indicators (EMAs, Supertrend): Lagging indicators that filter directional bias and keep you on the right side of major macro trends.
Momentum Oscillators (RSI, Stochastic): Leading bounded indicators that identify overextended extremes and momentum divergence.
Volatility Indicators (Bollinger Bands, ATR): Pure volatility measures that dictate optimal stop-loss distances and position sizing.

The institutional edge lies in multi-indicator confluence without redundancy. Combining 4 trend indicators (e.g. SMA, EMA, MACD, Supertrend) creates multicollinearity. Combining 1 Trend Filter (50 EMA) + 1 Momentum Oscillator (RSI Divergence) + 1 Volatility Measure (ATR Stop) builds an institutional trading system.

Real Market Walkthrough

RSI Bullish Divergence on Bank Nifty Daily Chart

Ref: BANKNIFTY Daily Timeframe
Context & Trigger

Bank Nifty made a lower low at 49,800, but RSI printed a clear higher low at 38 (vs 29 prior low).

Execution Mechanism

Confirmed that downside selling momentum was decelerating rapidly despite price printing lower lows.

Market Outcome

Triggered a 1,800-point mean-reverting rally back to the 50-day EMA over 8 trading sessions.

Key Quantitative Lesson

Momentum divergences identify exhaustion in prevailing trends before price action confirms the reversal.

Non-Negotiable Risk Guidelines

Always base stop-loss distances on multiples of ATR (e.g. 1.5x to 2.0x ATR) rather than fixed arbitrary rupee amounts.
Never buy simply because RSI is "oversold" (<30) in a raging downtrend; strong trends can keep RSI oversold for weeks.

Common Pitfalls & Remedies

Cluttering charts with 8 overlapping indicators creating analysis paralysis

Why it happens: Conflicting signals lead to indecision and missed high-probability executions.

Remedy: Keep charts clean: 1 trend filter, 1 momentum oscillator, and volume.

Frequently Asked Questions

What is a Bollinger Band Squeeze?

A Bollinger Band Squeeze occurs when the bands contract to historical lows, signaling extreme volatility compression that almost always resolves in an explosive multi-day breakout.
