Technical Indicators — Complete Guide
Master essential technical indicators: RSI, MACD, Moving Averages, Stochastic, ADX, and Volume indicators. Learn how to use them for trading signals and confirmations.
What Are Technical Indicators?
Technical indicators are mathematical calculations applied to price and/or volume data that help traders identify trends, momentum, volatility, and potential reversal points. They are tools — not crystal balls.
Important Reality
No single indicator is reliable on its own. Professional traders use indicators for CONFIRMATION, not as primary entry signals. Price action and market structure come first; indicators confirm what you already see.
Moving Averages (MA)
Simple Moving Average (SMA):
The average closing price over N periods.
SMA(20) = Sum of last 20 closes ÷ 20
Exponential Moving Average (EMA):
Gives more weight to recent prices, reacts faster.
Key Moving Averages:
| MA Period | Use Case | Timeframe |
|---|---|---|
| EMA 9/10 | Short-term momentum | M15-H1 |
| EMA 20/21 | Dynamic S/R, trend filter | H1-H4 |
| SMA/EMA 50 | Medium-term trend | H4-D1 |
| SMA/EMA 100 | Intermediate trend | D1 |
| SMA/EMA 200 | Long-term trend (institutional) | D1-W1 |
Trading Signals:
| Signal | Meaning | Action |
|---|---|---|
| Price above 200 MA | Bullish long-term trend | Look for longs |
| Price below 200 MA | Bearish long-term trend | Look for shorts |
| Golden Cross (50 MA crosses above 200 MA) | Bullish shift | Buy signal |
| Death Cross (50 MA crosses below 200 MA) | Bearish shift | Sell signal |
| Price pulls back to 20 EMA | Dynamic support in uptrend | Buy the dip |
| MAs fanning apart | Strong trend | Stay with trend |
| MAs converging | Trend weakening | Prepare for change |
RSI (Relative Strength Index)
What It Measures:
Momentum — speed and magnitude of price changes on a 0-100 scale.
Settings:
- Default period: 14
- Overbought: above 70
- Oversold: below 30
RSI Trading Strategies:
| Strategy | Condition | Action |
|---|---|---|
| Overbought/Oversold | RSI > 70 or < 30 | Wait for reversal confirmation |
| Divergence | Price makes new high, RSI makes lower high | Potential reversal |
| Centerline Crossover | RSI crosses above/below 50 | Trend direction shift |
| Hidden Divergence | Price pullback, RSI holds trend | Trend continuation |
| Range Shift | RSI stays 40-80 (bullish) or 20-60 (bearish) | Confirms trend bias |
RSI Divergence:
Bearish Divergence:
- Price: Higher High
- RSI: Lower High
- Signal: Momentum fading, potential drop
Bullish Divergence:
- Price: Lower Low
- RSI: Higher Low
- Signal: Selling pressure fading, potential rise
Pro Tip
In a strong uptrend, RSI can stay overbought (>70) for extended periods. Don't blindly sell because RSI is high — use it in context with market structure. Divergence is more reliable than overbought/oversold levels alone.
MACD (Moving Average Convergence Divergence)
Components:
- MACD Line: EMA(12) - EMA(26)
- Signal Line: EMA(9) of MACD Line
- Histogram: MACD Line - Signal Line
MACD Signals:
| Signal | Condition | Meaning |
|---|---|---|
| Bullish Crossover | MACD crosses above Signal | Momentum shifting bullish |
| Bearish Crossover | MACD crosses below Signal | Momentum shifting bearish |
| Histogram Growing | Bars getting taller | Trend strengthening |
| Histogram Shrinking | Bars getting shorter | Trend weakening |
| Zero Line Cross | MACD crosses above/below zero | Trend direction change |
| Divergence | MACD diverges from price | Potential reversal |
MACD Best Practices:
- Use on H4/D1 for most reliable signals
- Combine with price action (don't trade MACD alone)
- Histogram direction change = early warning
- Zero line acts as trend filter (above = bullish bias, below = bearish)
Stochastic Oscillator
What It Measures:
Where current price is relative to its high-low range over N periods.
Settings:
- Fast Stochastic: %K(14), %D(3)
- Slow Stochastic: Smoothed version (less noise)
- Overbought: above 80
- Oversold: below 20
Stochastic Signals:
| Signal | Condition | Action |
|---|---|---|
| Bullish | %K crosses above %D below 20 | Potential buy |
| Bearish | %K crosses below %D above 80 | Potential sell |
| Divergence | Price vs. Stochastic diverge | Reversal warning |
| Double bottom | Stochastic dips twice below 20 | Strong buy setup |
ADX (Average Directional Index)
What It Measures:
Trend strength (not direction) on a 0-100 scale.
ADX Levels:
| ADX Value | Meaning | Trading Approach |
|---|---|---|
| 0-20 | No trend (ranging) | Range/mean reversion strategies |
| 20-25 | Weak trend emerging | Watch for breakout |
| 25-50 | Strong trend | Trend following strategies |
| 50-75 | Very strong trend | Stay with trend, don't counter |
| 75-100 | Extreme trend (rare) | Trend may exhaust soon |
ADX + DI Lines:
- +DI above -DI: Bullish bias
- -DI above +DI: Bearish bias
- ADX rising: Trend strengthening
- ADX falling: Trend weakening
Volume Indicators
On-Balance Volume (OBV):
- Cumulative volume (adds on up days, subtracts on down days)
- Rising OBV confirms uptrend
- Falling OBV confirms downtrend
- OBV divergence = potential reversal
Volume Moving Average:
- Compare current volume to average
- Above average = significant move (likely to continue)
- Below average = weak move (may reverse)
Volume Profile (Advanced):
- Shows volume at each price level
- High Volume Nodes (HVN) = support/resistance zones
- Low Volume Nodes (LVN) = price moves quickly through
- Point of Control (POC) = highest traded level
Combining Indicators
The Confluence Approach:
Strong Buy Signal = Multiple confirmations:
1. Price above 200 EMA (bullish trend) ✅
2. RSI above 50 but below 70 (room to grow) ✅
3. MACD crossing above signal (momentum shift) ✅
4. ADX above 25 (trend present) ✅
5. Volume above average (real participation) ✅
= HIGH PROBABILITY SETUP
Avoid Over-Analysis:
- Maximum 2-3 indicators per chart
- All indicators should serve different purposes
- Don't use 3 momentum indicators together (redundant)
- Best combination: Trend + Momentum + Volume
