12 Technical Indicators Every Crypto and Stock Trader Should Know
Twelve essential technical indicators explained: RSI, MACD, Bollinger Bands, ATR, VWAP, OBV, and more — what each measures and how traders apply them.
Indicators Are Tools, Not Predictions
Technical indicators are among the most widely used tools in trading.
Yet many traders misunderstand their purpose.
Indicators do not predict the future.
They help interpret existing price behavior and momentum.
Used correctly, they provide additional context for evaluating trade setups.
Trend Indicators
Trend indicators help determine the direction of the market.
Moving Averages
Moving averages smooth price data and highlight trends.
Common types include:
- Simple Moving Average (SMA)
- Exponential Moving Average (EMA)
Traders often monitor crossovers and interactions with long-term averages such as the 200-day moving average.
Ichimoku Cloud
The Ichimoku system provides a multi-dimensional view of trend, support, resistance, and momentum in a single framework.
Momentum Indicators
Momentum indicators measure the speed and strength of price movements.
Relative Strength Index (RSI)
RSI ranges from 0 to 100 and measures momentum strength.
Common interpretations include:
- Overbought above 70
- Oversold below 30
MACD
MACD tracks the relationship between two moving averages.
Traders often watch for signal-line crossovers and histogram shifts.
Volatility Indicators
Volatility indicators measure how much price typically moves.
Bollinger Bands
Bollinger Bands expand and contract with volatility.
Price touching the upper or lower band may signal extreme conditions.
Average True Range (ATR)
ATR measures typical price movement over a given period.
It is often used for stop-loss placement.
Volume Indicators
Volume reflects participation in a move.
Volume
High volume confirms strong interest from market participants.
On-Balance Volume (OBV)
OBV tracks cumulative buying and selling pressure.
Other Useful Tools
VWAP
Volume Weighted Average Price reflects the average price weighted by trading volume.
Stochastic Oscillator
This indicator compares closing prices to recent trading ranges.
Parabolic SAR
Used to identify potential trend reversals.
Fibonacci Retracement
Used to identify potential retracement levels within a trend.
