1. What Are Technical Indicators?
✓ Leading Indicators
Attempt to signal a move before it confirms in price. Examples: RSI, Stochastic RSI, Williams %R. They generate earlier entries but produce more false signals — particularly during strong trends, when oscillators can stay overbought or oversold for weeks (BTC's RSI held above 70 for most of February–March 2024 around the spot ETF launch).
✓ Lagging Indicators
Confirm a move after it has started. Examples: Moving Averages, MACD, Bollinger Bands. They produce fewer false signals but enter later — the 50/200 SMA 'golden cross' on BTC in October 2023 fired roughly 8 weeks after the local low near $25,000.
2. Moving Averages (SMA & EMA)
✓ Simple Moving Average (SMA)
Arithmetic mean of the last N closing prices, with each period weighted equally. Formula: SMA = (P₁ + P₂ + … + Pₙ) / n. Best for: identifying long-term trends. The 200-day SMA is the most widely tracked trend filter on BTC daily charts; price has historically spent roughly 60–70% of bull-cycle time above it.
✓ Exponential Moving Average (EMA)
Weights recent prices more heavily, reacting faster than the SMA. Formula: EMA = Price × k + EMA_prev × (1 − k), where k = 2 / (N+1). Best for: short-term trading on 1H–4H charts. The 21 EMA is a common dynamic support level traders watch on BTC and ETH during trending phases.
✓ Key Moving Average Signals
Golden Cross: 50 SMA crosses above the 200 SMA — historically associated with bullish phases. Death Cross: 50 SMA crosses below the 200 SMA — historically associated with bearish phases. Price above the 200 SMA is often used as a coarse bull/bear filter. Note: both crosses are lagging, and both produced whipsaws during BTC's 2019 and 2023 ranges.
3. Relative Strength Index (RSI)
✓ What Is RSI?
The Relative Strength Index, developed by J. Welles Wilder in 1978, measures the magnitude of recent gains versus losses on a 0–100 scale over a default 14-period lookback. Readings above 70 are conventionally labelled overbought; readings below 30, oversold. In strong trends these thresholds frequently fail — BTC daily RSI stayed above 70 for most of November 2024 as price ran from $70k to $108k.
✓ RSI Divergence
Bearish divergence: price prints a higher high while RSI prints a lower high — momentum is fading. Bullish divergence: price prints a lower low while RSI prints a higher low. Divergence is a context tool, not an entry trigger; it can persist for weeks before price reacts. ETH's daily chart in mid-2021 showed three consecutive bearish divergences before the May 2021 drawdown.
4. MACD (Moving Average Convergence Divergence)
✓ What Is MACD?
The MACD (Moving Average Convergence Divergence), introduced by Gerald Appel in the late 1970s, shows the relationship between two EMAs. It has three components: the MACD Line (12 EMA − 26 EMA), the Signal Line (9 EMA of the MACD line), and the Histogram (MACD − Signal). Default settings are 12/26/9 — most charting platforms including TradingView, Binance, and Bybit use these out of the box.
✓ Bullish MACD Cross
MACD line crosses above the signal line, often with the histogram flipping positive. Historically associated with building upward momentum, though it lags price — by the time the cross prints, the move is typically several candles old. Most reliable when it occurs above the zero line in an established uptrend.
✓ Bearish MACD Cross
MACD line crosses below the signal line. Historically associated with weakening momentum. False crosses are common in sideways ranges; many traders ignore signals when the MACD line is hovering near zero or when ATR is unusually low.
5. Bollinger Bands
✓ What Are Bollinger Bands?
Developed by John Bollinger in the 1980s, Bollinger Bands consist of a middle band (typically the 20-period SMA) and two outer bands placed 2 standard deviations above and below. Roughly 95% of price action falls inside the bands under a normal distribution — though crypto returns have fatter tails, so band breaks happen more often than the model implies. Bands expand during high volatility and contract during consolidation.
✓ Bollinger Band Squeeze
When the bands narrow to a multi-month low (a 'squeeze'), realised volatility has compressed and a larger range expansion typically follows. The squeeze does not predict direction — only that the prevailing low-volatility regime is unsustainable. BTC's August 2023 squeeze near $26k preceded a sharp move in either direction; traders generally wait for the breakout candle and volume confirmation before acting.
6. Volume
✓ Why Volume Matters
Volume measures the units traded in a given period and contextualises price moves. High volume on a breakout suggests broad participation; low volume suggests thin liquidity and a higher chance of a fade. Crypto volume varies dramatically by venue — Binance spot typically accounts for 40–55% of centralised BTC/USDT volume, so reading volume from a single illiquid pair can mislead.
✓ Volume Patterns
Rising price + rising volume: trend has participation. Rising price + falling volume: trend is thinning, raising reversal odds. Falling price + high volume: distribution or capitulation — both extremes have appeared near major BTC lows (e.g. November 2022 post-FTX) and tops. Volume alone doesn't determine direction; pair it with a price-structure read.
7. Stochastic RSI
✓ What Is Stochastic RSI?
Created by Tushar Chande and Stanley Kroll in 1994, the Stochastic RSI applies the Stochastic oscillator formula to RSI values instead of price. It oscillates between 0 and 1 (or 0–100) and is markedly more sensitive than standard RSI. Readings above 0.8 are conventionally overbought; below 0.2, oversold. Because it whipsaws on lower timeframes, it's most informative on the 4H or daily.
✓ Reading Stochastic RSI
Crossovers of the %K and %D lines inside extreme zones are the standard reference points. The indicator can pin at 0 or 100 for extended periods during strong trends — treating every crossover as an entry produces poor results in trending crypto markets. Most setups combine it with a higher-timeframe trend filter such as the 50 or 200 SMA.
8. Combining Indicators
Establish the Trend
Use Moving Averages (50 SMA and 200 SMA on the daily) to determine direction. Trades aligned with the higher-timeframe trend have historically had better risk/reward profiles than counter-trend setups. If the two MAs are flat and intertwined, the market is ranging — different tools (Bollinger Bands, support/resistance) apply.
Gauge Momentum
Add RSI or MACD to check whether momentum supports the trend. In an uptrend, RSI pullbacks into the 40–50 zone are common reset points; in a downtrend, rallies into 50–60 are common. Watch for divergences as a heads-up that the prevailing trend is losing strength.
Check Volume
Confirm the move with volume. Breakouts or reversals on volume well above the 20-period average are more reliable than those on flat volume. On Binance, OKX, and Bybit, perpetual futures volume often leads spot — a divergence between the two can flag positioning-driven moves rather than organic flow.
Time the Entry
Use Bollinger Bands or Stochastic RSI to refine entry timing within the higher-timeframe trend. In an uptrend, pullbacks toward the lower band with Stochastic RSI in oversold territory are common entry zones. Define the invalidation level (stop loss) and position size before placing the order, not after.

Derivatives & Leveraged Products — Important Risk Warning
Derivatives are complex financial instruments that carry a high risk of rapid capital loss. Leveraged trading (futures, perpetual contracts, margin trading, options) can result in losses that exceed your initial investment. The majority of retail investor accounts lose money when trading derivatives.
You should carefully consider whether you understand how derivatives work and whether you can afford to take the high risk of losing your money. This content is for educational purposes only and does not constitute financial advice, investment advice, or a recommendation to trade derivatives.
In the European Union, crypto derivatives are classified as financial instruments under MiFID II. Only platforms with appropriate MiFID II authorization may offer these products to EU residents. Regulatory treatment varies by jurisdiction — verify the legal status of derivatives trading in your country before participating.
