1. What Are Technical Indicators?
Technical indicators are mathematical calculations based on price, volume, or open interest data. They transform raw market data into visual signals that help traders identify trends, momentum, volatility, and potential reversal points.
Think of indicators as lenses — each one shows you a different aspect of the same market. No single indicator tells the complete story, but combining the right ones gives you a much clearer picture of what's happening and what might happen next.
leading_indicators
Signal before a move happens. Examples: RSI, Stochastic RSI. More false signals, but earlier entries.
lagging_indicators
Confirm after a move starts. Examples: Moving Averages, MACD. Fewer false signals, but later entries.
2. Moving Averages (SMA & EMA)
A Moving Average (MA) smooths out price data by calculating the average price over a specific number of periods. It's the most fundamental indicator in technical analysis and forms the basis of many other tools.
Simple Moving Average (SMA)
Calculates the arithmetic mean of the last N closing prices. Each period is weighted equally.
sma
Best for: Identifying long-term trends. The 200-day SMA is the most widely watched level in all of finance.
Exponential Moving Average (EMA)
Gives more weight to recent prices, making it more responsive to new information than the SMA.
ema_price_emaprev × (1 − k)
Best for: Short-term trading. Reacts faster to price changes, reducing lag.
Key Moving Average Signals

Death Cross: death_cross_desc

Price below MA: when_price_trades_below_key
Popular MA periods: 9 & 21 EMA for short-term, 50 SMA for medium-term, 200 SMA for long-term trend. In crypto, the 20 EMA on the 4H chart is heavily used by swing traders.
3. Relative Strength Index (RSI)
The RSI measures the speed and magnitude of recent price changes on a scale of 0 to 100. It tells you whether an asset is overbought (potentially too expensive) or oversold (potentially undervalued).
overbought
RSI above 70
the_asset_has_risen_sharply
oversold
RSI below 30
the_asset_has_fallen_sharply
RSI Divergence: When price makes a new high but RSI makes a lower high, it's bearish divergence — momentum is weakening. The opposite (price lower low, RSI higher low) is bullish divergence. Divergences are among the most reliable reversal signals.
4. MACD (Moving Average Convergence Divergence)
The MACD is a trend-following momentum indicator that shows the relationship between two EMAs. It consists of three components: the MACD Line, the signal line, and the histogram.

5. Bollinger Bands
Bollinger Bands measure volatility by placing bands above and below a moving average. The bands expand when volatility increases and contract when it decreases, giving you a dynamic view of price range.
Three Components

bb_middle_band

bb_lower_band

lower_band_meaning
Bollinger Squeeze
When the bands contract tightly, it signals low volatility — a big move is often coming. The direction of the breakout (up or down) determines the trade. Used by momentum traders to time entries.
Band Walk
In strong trends, price can "walk" along the upper or lower band for extended periods. This is not a reversal signal — it shows sustained momentum. Don't short just because price is at the upper band in an uptrend.
Bollinger + RSI combo: When price touches the lower Bollinger Band AND RSI is below 30, it's a stronger oversold signal than either indicator alone. This combination filters out many false signals.
6. Volume
Volume measures how many units of an asset were traded during a given period. It's the confirmation indicator — it validates or invalidates signals from other tools. Price movements on high volume are more significant than those on low volume.
| Price Action | Volume | Interpretation |
|---|---|---|
| vol_price_rising | vol_high | vol_interp_rising_high |
| vol_price_rising | vol_low | vol_interp_rising_low |
| vol_price_falling | vol_high | vol_interp_falling_high |
| vol_price_falling | vol_low | vol_interp_falling_low |
| vol_breakout | vol_high | vol_interp_breakout_high |
| vol_breakout | vol_low | vol_interp_breakout_low |
⚠️ Crypto volume caveat: Volume data on crypto exchanges can be inflated by wash trading. Focus on volume changes (spikes vs. average) rather than absolute numbers. Regulated exchanges (Kraken, Bitvavo) tend to report more reliable volume data.
7. Stochastic RSI
The Stochastic RSI applies the Stochastic oscillator formula to RSI values instead of price. It's an indicator of an indicator — more sensitive than standard RSI, generating signals faster (but with more noise).
How It Differs from RSI

- more_sensitive_reaches_extremes_more
- better_for_identifying_short_term
- more_false_signals_than_standard

- below_20 oversold_zone_watch_for_bullish
- K crosses above D: bullish_signal_especially_from_oversold
- K crosses below D: bearish_signal_especially_from_overbought
8. Combining Indicators
The real power of indicators comes from confluence — when multiple independent signals align. Here are three beginner-friendly combinations:
Trend + Momentum
Reliability: combo_strength_high50 EMA + RSI
combo_trend_momentum_logic
Volatility + Momentum
Reliability: combo_strength_medium_highBollinger Bands + RSI
combo_volatility_momentum_logic
Trend + Trend Confirmation
Reliability: combo_strength_highEMA Crossover + MACD
combo_ema_macd_logic
Avoid redundancy: Don't combine indicators that measure the same thing. RSI + Stochastic RSI is redundant (both measure momentum). Instead, pair a trend indicator with a momentum indicator and volume for three independent confirmations.
