What Are Technical Indicators?
Technical indicators are mathematical formulas applied to market data (such as price, volume, or open interest) to produce signals that guide investment decisions. They fall into categories like:
Trend indicators: Help determine the direction of the market (e.g., Moving Averages).
Momentum indicators: Measure the speed of price changes (e.g., RSI, MACD).
Volatility indicators: Show how much price moves in a given time (e.g., Bollinger Bands).
Volume indicators: Analyze trading volume to confirm price trends (e.g., OBV).
Top Indicators Every Crypto Investor Should Know
1. Moving Averages (MA)
Moving averages smooth out price action and help identify trends.
Simple Moving Average (SMA): Average of closing prices over a period.
Exponential Moving Average (EMA): Gives more weight to recent data.
✅ Use for: Trend confirmation and dynamic support/resistance.

2. Relative Strength Index (RSI)
RSI measures the magnitude of recent price changes to evaluate overbought or oversold conditions.
Value above 70 = Overbought
Value below 30 = Oversold
✅ Use for: Spotting reversal points and entry signals.

3. MACD (Moving Average Convergence Divergence)
MACD uses two EMAs to generate buy/sell signals.
Signal line crossovers indicate shifts in momentum.
Histogram shows the strength of the signal.
✅ Use for: Trend changes and momentum confirmation.
4. Bollinger Bands
Bollinger Bands consist of a moving average and two standard deviation bands above and below.
Prices nearing the upper band may be overbought.
Prices nearing the lower band may be oversold.
✅ Use for: Volatility analysis and breakout detection.
5. On-Balance Volume (OBV)
OBV tracks cumulative volume to detect accumulation or distribution trends.
Rising OBV with rising prices = confirmation.
Divergence between OBV and price = possible reversal.
✅ Use for: Validating trends using volume.
Creating Custom Crypto Indicators
Advanced investors may want to create their own indicators. Here’s how:
Define Your Objective: What behavior are you trying to detect (e.g., trend strength, breakout risk)?
Choose Inputs: Use price, volume, or even external data (social sentiment, on-chain metrics).
Apply Math/Logic: Use formulas or statistical models (e.g., z-scores, ratios).
Backtest & Optimize: Always test your indicator across different market conditions.
Visualize: Plot the indicator with your charts and test integration with your trading system.

Best Practices When Using Indicators
Combine indicators for confirmation (e.g., RSI + MA)
Avoid overfitting — too many indicators can create conflicting signals.
Use indicators alongside fundamental and sentiment analysis.
Regularly test performance as market behavior evolves.
