Crypto trading relies heavily on technical analysis indicators, which can be categorized into several types based on their functions and calculation methods. These tools help traders identify trends, gauge market sentiment, and predict potential price movements.
Core Categories of Technical Indicators
Moving Average Types
- Examples: MA (Simple Moving Average), EMA (Exponential Moving Average)
- Function: Analyze price trends using closing prices to create smooth trend lines
Momentum/Energy Types
- Examples: PSY (Psychological Line), BRAR (Emotion Ratio Indicator)
- Function: Measure market sentiment and trader psychology
Trend Following Types
- Examples: DMA (Different Moving Average), DMI (Directional Movement Index)
- Function: Identify and confirm market trends
Key Technical Indicators Explained
Relative Strength Index (RSI)
Concept
The RSI compares the magnitude of recent gains to recent losses to determine overbought or oversold conditions. It oscillates between 0-100 with standard thresholds:
- Overbought: 70+
- Oversold: 30-
Practical Applications
- Divergence Signals: When price makes new highs/lows without RSI confirmation
- Support/Resistance Levels: Often clearer on RSI charts than price charts
- Pattern Recognition: Technical patterns like head-and-shoulders appear more distinctly

Williams %R (WR)
Calculation
Measures the closing price relative to the high-low range over a set period (typically 14 days).
Trading Rules
| WR Level | Market Condition | Action |
|---|---|---|
| 0-20 | Extreme overbought | Sell |
| 80-100 | Extreme oversold | Buy |
| 20-80 | Neutral range | Hold/wait |
Parameter Variations
- Short-term (6-day): 15/85 thresholds
- Medium-term (20-day): 20/80 thresholds
- Long-term (70-day): 10/90 thresholds
KDJ Stochastic Oscillator
Components
- K Line: Fast stochastic
- D Line: Slow stochastic
- J Line: Signal confirmation
Interpretation
Overbought/Oversold
- D > 80: Overbought
- D < 20: Oversold
Crossover Signals
- Golden Cross (K↑D): Buy
- Death Cross (K↓D): Sell
Limitations
Not suitable for low-liquidity cryptocurrencies
Rate of Change (ROC)
Formula
ROC = [(Current Close - Close n periods ago) / Close n periods ago] × 100
Trading Guidelines
- Above zero line → Bullish momentum
- Below zero line → Bearish momentum
- Extreme readings (>+10% or <-10%) → Potential reversal signals
Bollinger Bands (BOLL)
Components
- Middle Band = 20-day SMA
- Upper Band = SMA + (2 × Standard Deviation)
- Lower Band = SMA - (2 × Standard Deviation)
Price Action Signals
| Scenario | Interpretation |
|---|---|
| Price touches upper band | Potential overbought |
| Price touches lower band | Potential oversold |
| Bands contract | Low volatility → Impending breakout |
| Bands expand | High volatility → Trend continuation |

Advanced Indicator Applications
Momentum Trading with MTM
- Positive momentum when MTM > 0
- Negative momentum when MTM < 0
- Watch for divergences between MTM and price
Psychological Line (PSY)
- Readings above 50 → Bullish sentiment
- Readings below 50 → Bearish sentiment
- Extremes (>75 or <25) → Potential reversals
FAQ Section
Q: Can I use multiple indicators together?
A: Yes! Combining RSI (for overbought/oversold) with Bollinger Bands (for volatility) often works well.
Q: What's the best timeframe for crypto indicators?
A: For day trading, use 15min-4hr charts with 14-period settings. For long-term, daily/weekly charts.
Q: How often should I adjust my indicator parameters?
A: Backtest different settings monthly, but avoid frequent changes that lead to overtrading.
Q: Do these indicators work in bear markets?
A: They remain effective but may generate more false signals during extreme volatility.
Q: Should I disregard fundamentals when using technical indicators?
A: Never. Always combine technical signals with fundamental analysis for comprehensive decisions.
Q: What's the biggest mistake beginners make with indicators?
A: Adding too many indicators rather than mastering 2-3 core ones thoroughly.
